On 24 February 2022,

After the

After taking part in Georgian Civil War and military conflicts in Ossetia, Abkhazia and Moldova in the beginning of the 1990s, Russian forces invaded Georgia in August 2008 and took control of the breakaway regions of Abkhazia and South Ossetia, demonstrating Russia's willingness to use military force to attain its political objectives.^[26] US administration "was accused of appeasement and naivete" on their reaction to the invasion.^[27]

In 2013,

Because of Russia's occupation of Crimea and its invasion of the Donbas, Ukraine's parliament voted in December 2014 to remove the neutrality clause from the Constitution and to seek Ukraine's membership in NATO.^[46][47] However, it was impossible for Ukraine to join NATO at the time, as any applicant nation must have no "unresolved external territorial disputes".^[48] In 2016, President of the European Commission, Jean-Claude Juncker, said that it would take 20–25 years for Ukraine to join the EU and NATO.^[49]

Negotiations started in 2014 and the Minsk agreements was reached, signed in September 2014 and February 2015, aiming for a resolution of the conflict, but ceasefires and further negotiations repeatedly failed.^[51]

There was a large Russian military build-up near the Ukraine border in March and April 2021,^[52] and again in both Russia and Belarus from October 2021 onward.^[53] Members of the Russian government, including Putin, repeatedly denied having plans to invade or attack Ukraine, with denials being issued up to the day before the invasion.^[54][55][56] The decision to invade Ukraine was reportedly made by Putin and a small group of war hawks or siloviki in Putin's inner circle, including national security adviser Nikolai Patrushev and defence minister Sergei Shoigu.^[57] Reports of an alleged leak of Russian Federal Security Service (FSB) documents by US intelligence sources said that the FSB had not been aware of Putin's plan to invade.^[58]

In July 2021, Putin published an essay "

Western leaders vowed that heavy sanctions would be imposed should Putin choose to invade rather than to negotiate.[72] French President Emmanuel Macron^[73] and German Chancellor Olaf Scholz met Putin in February 2022 to dissuade him from an invasion. According to Scholz, Putin told him that Ukraine should not be an independent state.^[74] Scholz told Ukrainian President Volodymyr Zelenskyy to declare Ukraine a neutral country and renounce its aspirations to join NATO. Zelenskyy replied that Putin could not be trusted to abide by such a settlement.^[75] Ukraine had been a neutral country in 2014 when Russia occupied Crimea and invaded the Donbas.^[76][77] On 19 February, Zelenskyy made a speech at the Munich Security Conference, calling for Western powers to drop their policy of "appeasement" towards Moscow and give a clear time-frame for when Ukraine could join NATO.^[78] As political analysts Taras Kuzio and Vladimir Socor agree, "when Russia made its decision to invade Ukraine, that country was more remote than ever not only from NATO membership but from any track that might lead to membership."^[66]

On 21 February, Putin

Before 5 a.m. Kyiv time on 24 February, Putin, in another speech, announced a "special military operation", which "effectively declar[ed] war on Ukraine."^[81][82] Putin said the operation was to "protect the people" of the Russian-controlled breakaway republics. He falsely claimed that they had "been facing humiliation and genocide perpetrated by the Kyiv regime."^[83] Putin said that Russia was being threatened: he falsely claimed that Ukrainian government officials were neo-Nazis under Western control, that Ukraine was developing nuclear weapons, and that a hostile NATO was building up its forces and military infrastructure in Ukraine.^[84] He said Russia sought the "demilitarization and denazification" of Ukraine, and espoused views challenging the legitimacy of the Ukrainian state.^[85][61] Putin said he had no plans to occupy Ukraine and supported the right of the Ukrainian people to self-determination.^[84]

The invasion began within minutes of Putin's speech.^[81]

The invasion began at dawn on 24 February.

Immediately after the invasion began, Zelenskyy declared martial law in Ukraine in a first video speech.^[96] The same evening, he ordered a general mobilisation of all Ukrainian males between 18 and 60 years old,^[97] prohibiting them from leaving the country.^[98] Wagner Group mercenaries and Kadyrovites contracted by the Kremlin reportedly made several attempts to assassinate Zelenskyy, including an operation involving several hundred mercenaries meant to infiltrate Kyiv with the aim of killing the Ukrainian president.^[99] The Ukrainian government said anti-war officials within Russia's FSB shared the plans with them.^[100] Zelenskiy appeared defiant in his first and following video message, showing in another on 25 February, that he and his cabinet is still in Kiyv. On 26 February NATO met and its countries pledged military aid for Ukraine and on 27 February Germany called the invasion a historic watershed.^[101] That day in the evening Putin put Russia's nuclear deterrence into alert.^[102]

The Russian invasion was unexpectedly met by fierce Ukrainian resistance.^[103] In Kyiv, Russia failed to take the city and was repulsed in the battles of Irpin, Hostomel, and Bucha. The Russians tried to encircle the capital, but its defenders under Oleksandr Syrskyi held their ground, effectively using Western Javelin anti-tank missiles and Stinger anti-aircraft missiles to thin Russian supply lines and stall the offensive.^[104]

On the southern front, Russian forces had captured the regional capital of

Ukraine's reliance on Western-supplied equipment constrained operational effectiveness, as supplying countries feared that Ukraine would use Western-made matériel to strike targets in Russia.^[112] Military experts disagreed on the future of the conflict; some suggested that Ukraine should trade territory for peace,^[113] while others believed that Ukraine could maintain its resistance due to Russian losses.^[114]

By 30 May, disparities between Russian and Ukrainian artillery were apparent, with Ukrainian artillery being vastly outgunned, in terms of both range and number.

On 29 June, Reuters reported that US Intelligence Director Avril Haines, in an update of past US intelligence assessments on the Russian invasion, said that US intelligence agencies agree that the invasion will continue "for an extended period of time ... In short, the picture remains pretty grim and Russia's attitude toward the West is hardening."^[117] On 5 July, BBC reported that extensive destruction by the Russian invasion would cause immense financial damage to Ukraine's reconstruction economy, with Ukrainian Prime Minister Denys Shmyhal telling nations at a reconstruction conference in Switzerland that Ukraine needs $750bn for a recovery plan and Russian oligarchs should contribute to the cost.^[118]

The invasion began on 24 February, launched out of Belarus to target Kyiv, and from the northeast against the city of Kharkiv. The southeastern front was conducted as two separate spearheads, from Crimea and the southeast against Luhansk and Donetsk.

Russian efforts to capture Kyiv included a probative spearhead on 24 February, from Belarus south along the west bank of the

Russian forces advanced into

On 4 March, Frederick Kagan wrote that the Sumy axis was then "the most successful and dangerous Russian avenue of advance on Kyiv", and commented that the geography favoured mechanised advances as the terrain "is flat and sparsely populated, offering few good defensive positions."^[88] Travelling along highways, Russian forces reached Brovary, an eastern suburb of Kyiv, on 4 March.^[89][88] The Pentagon confirmed on 6 April that the Russian army had left Chernihiv Oblast, but Sumy Oblast remained contested.^[144] On 7 April, the governor of Sumy Oblast said that Russian troops were gone, but had left behind rigged explosives and other hazards.^[145]

On 24 February, Russian forces took control of the

The Russian 22nd Army Corps approached the Zaporizhzhia Nuclear Power Plant on 26 February^[151] and besieged Enerhodar. A fire began,^[152][153] but the Ukrainian military said that essential equipment was undamaged.^[154] A third Russian attack group from Crimea moved northwest and captured the bridge over the Dnieper.^[155] On 2 March, Russian troops took Kherson; this was the first major city to fall to Russian forces.^[156] Russian troops moved on Mykolaiv and attacked it two days later. They were repelled by Ukrainian forces.^[157]

After renewed missile attacks on 14 March in Mariupol, the Ukrainian government said more than 2,500 had died.

Putin told Emmanuel Macron in a phone call on 29 March that the bombardment of Mariupol would only end when the Ukrainians surrendered.[163] On 1 April, Russian troops refused safe passage into Mariupol to 50 buses sent by the United Nations to evacuate civilians, as peace talks continued in Istanbul.^[164] On 3 April, following the retreat of Russian forces from Kyiv, Russia expanded its attack on southern Ukraine further west, with bombardment and strikes against Odesa, Mykolaiv, and the Zaporizhzhia Nuclear Power Plant.^[165][166]

In the east, Russian troops

Amid the heightened Russian shelling of Kharkiv on 31 March, Russia reported a helicopter strike against an oil supply depot approximately 35 kilometres (22 mi) north of the border in Belgorod, and accused Ukraine of the attack.^[177] Ukraine denied responsibility.^[178] By 7 April, the renewed massing of Russian invasion troops and tank divisions around the towns of Izium, Sloviansk, and Kramatorsk prompted Ukrainian government officials to advise the remaining residents near the eastern border of Ukraine to evacuate to western Ukraine within 2–3 days, given the absence of arms and munitions previously promised to Ukraine by then.^[179]

By 17 April, Russian progress on the southeastern front appeared to be impeded by opposing Ukrainian forces in the large, heavily fortified Azovstal steel mill and surrounding area in Mariupol.^[180]

On 19 April, The New York Times confirmed that Russia had launched a renewed invasion front referred to as an "eastern assault" across a 480-kilometre (300 mi) front extending from Kharkiv to Donetsk and Luhansk, with simultaneous missile attacks again directed at Kyiv in the north and Lviv in western Ukraine.^[181] As of 30 April, a NATO official described Russian advances as "uneven" and "minor."^[182] An anonymous US Defence official called the Russian offensive "very tepid", "minimal at best", and "anaemic."^[183] In June 2022 the chief spokesman for the

Russian Ground Forces started recruiting volunteer battalions from the regions in June 2022 to create a new 3rd Army Corps within the Western Military District, with a planned strength estimated at 15,500–60,000 personnel.^[186] Its units were deployed to the front around the time of Ukraine's 9 September Kharkiv oblast counteroffensive, in time to join the Russian retreat, leaving behind tanks, infantry fighting vehicles, and personnel carriers: the 3rd Army Corps "melted away" according to Forbes, having little or no impact on the battlefield along with other irregular forces.^[187]

On 13 April, Russian forces intensified their attack on the Azovstal Iron and Steel Works in Mariupol, and the remaining Ukrainian personnel defending it.^[188] By 17 April, Russian forces had surrounded the factory. Ukrainian prime minister Denys Shmyhal said that the Ukrainian soldiers had vowed to ignore the renewed ultimatum to surrender and to fight to the last soul.^[180] On 20 April, Putin said that the siege of Mariupol could be considered tactically complete, since the 500 Ukrainian troops entrenched in bunkers within the Azovstal iron works and estimated 1,000 Ukrainian civilians were completely sealed off from any type of relief.^[189]

After consecutive meetings with Putin and Zelenskyy, UN Secretary-General Guterres on 28 April said he would attempt to organise an emergency evacuation of survivors from Azovstal in accordance with assurances he had received from Putin on his visit to the Kremlin.^[190] On 30 April, Russian troops allowed civilians to leave under UN protection.^[191] By 3 May, after allowing approximately 100 Ukrainian civilians to depart from the Azovstal steel factory, Russian troops renewed their bombardment of the steel factory.^[192] On 6 May, The Daily Telegraph reported that Russia had used thermobaric bombs against the remaining Ukrainian soldiers, who had lost contact with the Kyiv government; in his last communications, Zelenskyy authorised the commander of the besieged steel factory to surrender as necessary under the pressure of increased Russian attacks.^[193] On 7 May, the Associated Press reported that all civilians were evacuated from the Azovstal steel works at the end of the three-day ceasefire.^[194]

After the last civilians evacuated from the Azovstal bunkers, nearly two thousand Ukrainian soldiers remained barricaded there, 700 of them injured. They were able to communicate a plea for a military corridor to evacuate, as they expected summary execution if they surrendered to Russian forces.^[195] Reports of dissent within the Ukrainian troops at Azovstal were reported by Ukrainska Pravda on 8 May indicating that the commander of the Ukrainian marines assigned to defend the Azovstal bunkers made an unauthorised acquisition of tanks, munitions, and personnel, broke out from the position there and fled. The remaining soldiers spoke of a weakened defensive position in Azovstal as a result, which allowed progress to advancing Russian lines of attack.^[196] Ilia Somolienko, deputy commander of the remaining Ukrainian troops barricaded at Azovstal, said: "We are basically here dead men. Most of us know this and it's why we fight so fearlessly."^[197]

On 16 May, the Ukrainian General staff announced that the Mariupol garrison had "fulfilled its combat mission" and that final evacuations from the Azovstal steel factory had begun. The military said that 264 service members were evacuated to Olenivka under Russian control, while 53 of them who were "seriously injured" had been taken to a hospital in

A Russian missile attack on Kramatorsk railway station in the city of Kramatorsk took place on 8 April, reportedly killing at least 52 people^[201] and injuring as many as 87 to 300.^[202] On 11 April, Zelenskyy said that Ukraine expected a major new Russian offensive in the east.^[203] American officials said that Russia had withdrawn or been repulsed elsewhere in Ukraine, and therefore was preparing a retraction, resupply, and redeployment of infantry and tank divisions to the southeastern Ukraine front.^[204][205] Military satellites photographed extensive Russian convoys of infantry and mechanised units deploying south from Kharkiv to Izium on 11 April, apparently part of the planned Russian redeployment of its northeastern troops to the southeastern front of the invasion.^[206]

On 18 April, with Mariupol almost entirely overtaken by Russian forces, the Ukrainian government announced that the second phase of the reinforced invasion of the Donetsk, Luhansk and Kharkiv regions had intensified with expanded invasion forces occupying of the Donbas.^[207]

On 22 May, the BBC reported that after the fall of Mariupol, Russia had intensified offensives in Luhansk and Donetsk while concentrating missile attacks and intense artillery fire on Sievierodonetsk, the largest city under Ukrainian control in Luhansk province.^[208]

On 23 May, Russian forces were reported entering the city of Lyman, fully capturing the city by 26 May.^[209][210] Ukrainian forces were reported leaving Sviatohirsk.^[211] By 24 May, Russian forces captured the city of Svitlodarsk.^[212] On 30 May, Reuters reported that Russian troops had breached the outskirts of Sievierodonetsk.^[213] By 2 June, The Washington Post reported that Sievierodonetsk was on the brink of capitulation to Russian occupation with over 80 per cent of the city in the hands of Russian troops.^[214] On 3 June, Ukrainian forces reportedly began a counter-attack in Sievierodonetsk. By 4 June, Ukrainian government sources claimed 20% or more of the city had been recaptured.^[215]

On 12 June, it was reported that possibly as many as 800 Ukrainian civilians (as per Ukrainian estimates) and 300–400 soldiers (as per Russian sources) were besieged at the Azot chemical factory in Severodonetsk.^[216][217] With the Ukrainian defences of Severodonetsk faltering, Russian invasion troops began intensifying their attack upon the neighbouring city of Lysychansk as their next target city in the invasion.^[218] On 20 June it was reported that Russian troops continued to tighten their grip on Severodonetsk by capturing surrounding villages and hamlets surrounding the city, most recently the village of Metelkine.^[219]

On 24 June, CNN reported that, amid continuing scorched-earth tactics being applied by advancing Russian troops, Ukraine's armed forces were ordered to evacuate the Severodonetsk; several hundred civilians taking refuge in the Azot chemical plant were left behind in the withdrawal, with some comparing their plight to that of the civilians at the Azovstal steel works in Mariupol in May.^[220] On 3 July, CBS announced that the Russian defence ministry claimed that the city of Lysychansk had been captured and occupied by Russian forces.^[221] On 4 July, The Guardian reported that after the fall of the Luhansk oblast, that Russian invasion troops would continue their invasion into the adjacent Donetsk Oblast to attack the cities of Sloviansk and Bakhmut.^[222]

On 14 April, Ukrainian troops reportedly blew up a bridge between Kharkiv and Izium used by Russian forces to redeploy troops to Izium, impeding the Russian convoy.^[223]

On 5 May, David Axe writing for Forbes stated that the Ukrainian army had concentrated its 4th and 17th Tank Brigades and the 95th Air Assault Brigade around Izium for possible rearguard action against the deployed Russian troops in the area; Axe added that the other major concentration of Ukraine's forces around Kharkiv included the 92nd and 93rd Mechanised Brigades which could similarly be deployed for rearguard action against Russian troops around Kharkiv or link up with Ukrainian troops contemporaneously being deployed around Izium.^[224]

On 13 May, BBC reported that Russian troops in Kharkiv were being retracted and redeployed to other fronts in Ukraine following the advances of Ukrainian troops into surrounding cities and Kharkiv itself, which included the destruction of strategic pontoon bridges built by Russian troops to cross over the Seversky Donets river and previously used for rapid tank deployment in the region.^[225]

Missile attacks and bombardment of the key cities of Mykolaiv and Odesa continued as the second phase of the invasion began.^[181] On 22 April 2022, Russia's Brigadier General Rustam Minnekayev in a defence ministry meeting said that Russia planned to extend its Mykolaiv–Odesa front after the siege of Mariupol further west to include the breakaway region of Transnistria on the Ukrainian border with Moldova.^[226] The Ministry of Defence of Ukraine called this plan imperialism and said that it contradicted previous Russian claims that it did not have territorial ambitions in Ukraine and also that the statement admitted that "the goal of the 'second phase' of the war is not victory over the mythical Nazis, but simply the occupation of eastern and southern Ukraine."^[226] Georgi Gotev of EURACTIV noted on 22 April that Russian occupation from Odesa to Transnistria would transform Ukraine into a landlocked nation with no practical access to the Black Sea.^[227] Russia resumed its missile strikes on Odesa on 24 April, destroying military facilities and causing two dozen civilian casualties.^[228]

Explosions destroyed two Russian broadcast towers in Transnistria on 27 April that had primarily rebroadcast Russian television programming, Ukrainian sources said.^[229] Russian missile attacks at the end of April destroyed runways in Odesa.^[230] In the week of 10 May, Ukrainian troops began to dislodge Russian forces from Snake Island in the Black Sea approximately 200 kilometres (120 mi) from Odesa.^[231] Russia said on 30 June 2022 that it had withdrawn its troops from the island, once their objectives had been completed.^[232]

On 23 July, CNBC reported a Russian missile strike on the Ukrainian port of Odesa, swiftly condemned by world leaders amid a recent

Russian forces continued to fire missiles and drop bombs on the key cities of

Ukrainian nuclear agency Energoatom called the situation at the Zaporizhzhia nuclear power plant "extremely tense", although it was still operated by its Ukrainian staff. As many as 500 Russian soldiers controlled the plant; Kyiv's nuclear agency said they were shelling nearby areas and storing weapons and "missile systems" there. Almost the entire country went on air raid alert. "They already shell the other side of the river Dnipro and the territory of Nikopol," Energoatom president Pedro Kotin said.^[238] Russia agreed on 19 August to allow IAEA inspectors access to the Zaporizhzhia plant after a phone call from Macron to Putin. As of July 2023, however, access to the plant remained limited and required extensive negotiation.^[239]

Russia reported that 12 attacks with explosions from 50 artillery shells had been recorded by 18 August at the plant and the company town of Enerhodar.^[240] Tobias Ellwood, chair of the UK's Defence Select Committee, said on 19 August that any deliberate damage to the Zaporizhzhia nuclear plant that could cause radiation leaks would be a breach of Article 5 of the North Atlantic Treaty, under which an attack on a member state of NATO is an attack on them all. US congressman Adam Kinzinger said the following day that any radiation leak would kill people in NATO countries, an automatic activation of Article 5.^[241][242]

Shelling hit

Incoming power was still available across the 330 kV line to the substation at the coal-fired station, so the diesel generators were not essential for cooling reactor cores and spent fuel pools. The 750 kV line and reactor 6 resumed operation at 12:29 p.m., but the line was cut by fire again two hours later. The line, but not the reactors, resumed operation again later that day.^[243] On 26 August, one reactor restarted in the afternoon and another in the evening, resuming electricity supplies to the grid.^[244] On 29 August 2022, an IAEA team led by Rafael Grossi went to the plant to investigate.^[245] Lydie Evrard and Massimo Aparo were also on the team. No leaks had been reported at the plant before their arrival, but shelling had occurred days before.^[246]

On 6 September 2022, Ukrainian forces launched a surprise counteroffensive in the Kharkiv region, beginning near Balakliia, led by General Syrskyi.^[247] An emboldened Kyiv launched a counteroffensive 12 September around Kharkiv successful enough to make Russia admit losing key positions and for The New York Times to say that it dented the image of a "Mighty Putin". Kyiv sought more arms from the West to sustain the counteroffensive.^[248] On 21 September 2022, Vladimir Putin announced a partial mobilisation and Minister of Defence Sergei Shoigu said 300,000 reservists would be called.^[249] He also said that his country would use "all means" to "defend itself." Mykhailo Podolyak, an adviser to Zelenskyy, said that the decision was predictable and that it was an attempt to justify "Russia's failures."^[250] British Foreign Office Minister Gillian Keegan called the situation an "escalation",^[251] while former Mongolian president Tsakhiagiin Elbegdorj accused Russia of using Russian Mongols as "cannon fodder."^[252]

In late September 2022, Russian-installed officials in Ukraine organised

On 30 September 2022, Vladimir Putin announced the annexation of Ukraine's Donetsk, Luhansk, Kherson and Zaporizhzhia regions in an address to both houses of the Russian parliament.^[254] Ukraine, the United States, the European Union and the United Nations all denounced the annexation as illegal.^[255]

An

On 29 August, Zelenskyy advisedly vowed the start of a full-scale counteroffensive in the southeast. He first announced a counteroffensive to retake Russian-occupied territory in the south concentrating on the Kherson-Mykolaiv region, a claim that was corroborated by the Ukrainian parliament as well as Operational Command South.^[259]

On 4 September, Zelenskyy announced the liberation of two unnamed villages in Kherson Oblast and one in Donetsk Oblast. Ukrainian authorities released a photo showing the raising of the Ukrainian flag in Vysokopillia by Ukrainian forces.^[260] Ukrainian attacks also continued along the southern frontline, though reports about territorial changes were largely unverifiable.^[261] On 12 September, Zelenskyy said that Ukrainian forces had retaken a total of 6,000 square kilometres (2,300 sq mi) from Russia, in both the south and the east. The BBC stated that it could not verify these claims.^[262]

In October, Ukrainian forces pushed further south towards the city of Kherson, taking control of 1,170 square kilometres (450 sq mi) of territory, with fighting extending to Dudchany.^[263][264] On 9 November, defence minister Shoigu ordered Russian forces to leave part of Kherson Oblast, including the city of Kherson, and move to the eastern bank of the Dnieper.^[265] On 11 November, Ukrainian troops entered Kherson, as Russia completed its withdrawal. This meant that Russian forces no longer had a foothold on the west (right) bank of the Dnieper.^[266]

Map of the Kharkiv front as of 15 October 2024

Ukrainian forces launched another surprise counteroffensive on 6 September in the Kharkiv region near Balakliia led by General Syrskyi.^[247] By 7 September, Ukrainian forces had advanced some 20 kilometres (12 mi) into Russian occupied territory and claimed to have recaptured approximately 400 square kilometres (150 sq mi). Russian commentators said this was likely due to the relocation of Russian forces to Kherson in response to the Ukrainian offensive there.^[267] On 8 September, Ukrainian forces captured Balakliia and advanced to within 15 kilometres (9.3 mi) of Kupiansk.^[268] Military analysts said Ukrainian forces appeared to be moving towards Kupiansk, a major railway hub, with the aim of cutting off the Russian forces at Izium from the north.^[269]

On 9 September, the Russian occupation administration of Kharkiv Oblast announced it would "evacuate" the civilian populations of Izium, Kupiansk and Velykyi Burluk. The Institute for the Study of War (ISW) said it believed Kupiansk would likely fall in the next 72 hours,^[270] while Russian reserve units were sent to the area by both road and helicopter.^[271] On the morning of 10 September, photos emerged claiming to depict Ukrainian troops raising the Ukrainian flag in the centre of Kupiansk,^[272] and the ISW said Ukrainian forces had captured approximately 2,500 square kilometres (970 sq mi) by effectively exploiting their breakthrough.^[273] Later in the day, Reuters reported that Russian positions in northeast Ukraine had "collapsed" in the face of the Ukrainian assault, with Russian forces forced to withdraw from their base at Izium after being cut off by the capture of Kupiansk.^[274]

By 15 September, an assessment by

After the end of the twin Ukrainian counteroffensives, the fighting shifted to a semi-deadlock during the winter,^[277] with heavy casualties but reduced motion of the frontline.^[278] Russia launched a self-proclaimed winter offensive in eastern Ukraine, but the campaign ended in "disappointment" for Moscow, with limited gains as the offensive stalled.^[277][279] Analysts variously blamed the failure on Russia's lack of "trained men", and supply problems with artillery ammunition, among other problems.^[277][279] Near the end of May, Mark Galeotti assessed that "after Russia's abortive and ill-conceived winter offensive, which squandered its opportunity to consolidate its forces, Ukraine is in a relatively strong position."^[280]

On 7 February, The New York Times reported that Russians had newly mobilised nearly 200,000 soldiers to participate in the offensive in the Donbas, against Ukraine troops already wearied by previous fighting.^[281] The Russian private military company Wagner Group took on greater prominence in the war,^[282] leading "grinding advances" in Bakhmut with tens of thousands of recruits from prison battalions taking part in "near suicidal" assaults on Ukrainian positions.^[279]

In late January 2023, fighting intensified in the southern Zaporizhzhia region, with both sides suffering heavy casualties.

Following defeat in Kherson and Kharkiv, Russian and Wagner forces focused on taking the city of Bakhmut and breaking the half year long stalemate that prevailed there since the start of the war. Russian forces sought to encircle the city, attacking from the north via Soledar. After taking heavy casualties, Russian and Wagner forces took control of Soledar on 16 January 2023.^[286][287] By early February 2023, Bakhmut was facing attacks from north, south and east, with the sole Ukrainian supply lines coming from Chasiv Yar to the west.^[288]

On 3 March 2023, Ukrainian soldiers destroyed two key bridges, creating the possibility for a controlled fighting withdrawal from eastern sectors of Bakhmut.^[289] On 4 March, Bakhmut's deputy mayor told news services that there was street fighting in the city.^[290] On 7 March, despite the city's near-encirclement, The New York Times reported that Ukrainian commanders were requesting permission from Kyiv to continue fighting against the Russians in Bakhmut.^[291]

On 26 March, Wagner Group forces claimed to have fully captured the tactically significant Azom factory in Bakhmut.^[292] Appearing before the House Committee on Armed Services on 29 March, General Mark Milley, Chairman of the Joint Chiefs of Staff, reported that, "for about the last 20, 21 days, the Russia have not made any progress whatsoever in and around Bakhmut." Milley described the severe casualties being inflicted upon the Russian forces there as a "slaughter-fest."^[293]

By the beginning of May, the ISW assessed that Ukraine controlled only 1.89 square kilometres (0.73 sq mi) of the city, less than five percent.^[294] On 18 May 2023, The New York Times reported that Ukrainian forces had launched a local counteroffensive, taking back swathes of territory to the north and south of Bakhmut over the course of a few days.^[295] On 20 May 2023, the Wagner Group claimed full control over Bakhmut, and a victory in the battle was officially declared by Russia the next day,^[296] following which Wagner forces retreated from the city in place of regular Russian units.^[297]

In June 2023, Ukrainian forces gradually launched a series of counteroffensives on multiple fronts, including Donetsk Oblast, Zaporizhzhia Oblast, and others.

On 24 June, the Wagner Group launched a brief rebellion against the Russian government, capturing several cities in western Russia largely unopposed before marching towards Moscow.^[304] This came as the culmination of prolonged infighting and power struggles between Wagner and the Russian Ministry of Defence.^[305] After about 24 hours, the Wagner Group backed down^[306] and agreed to a peace deal in which Wagner leader Yevgeny Prigozhin would go into exile in Belarus, and his forces would be free from prosecution.^[304] On 27 June, the UK's Ministry of Defence reported that Ukraine were "highly likely" to have reclaimed territory in the eastern Donbas region occupied by Russia since 2014 among its advances. Pro-Russian bloggers also reported that Ukrainian forces had made gains in the southern Kherson region, establishing a foothold on the left bank of the Dnipro river after crossing it.^[307]

In August, The Guardian reported that Ukraine had become the most mined country in the world, with Russia laying millions of mines attempting to thwart Ukraine's counteroffensive. The vast minefields forced Ukraine to extensively de-mine areas to allow advances. Ukrainian officials reported shortages of men and equipment as Ukrainian soldiers unearthed five mines for every square metre in certain places.^[308]

Following Russia pulling out of the Black Sea Grain Initiative, the conflict on the Black Sea escalated with Ukraine targeting Russian ships. On 4 August, Ukrainian security service sources reported that the Russian landing ship Olenegorsky Gornyak had been hit and damaged by an unmanned naval drone. Video footage released by Ukraine's security services appeared to show the drone striking the ship, with another video showing the ship seemingly listing to one side.^[309] On 12 September, both Ukrainian and Russian sources reported that Russian naval targets in Sevastopol had been struck by unconfirmed weaponry, damaging two military vessels, one of them reportedly a submarine.^[310] Ukraine also reported that several oil and gas drilling platforms on the Black Sea held by Russia since 2015 had been retaken.^[311]

In September 2023, Ukrainian intelligence estimated that Russia had deployed over 420,000 troops in Ukraine.^[312]

On 21 September, Russia began missile strikes across Ukraine, damaging the country's energy facilities.

In October 2023, it was reported that there was a growth of mutinies among Russian troops due to large amount of losses in Russian offensives around Avdiivka with a lack of artillery, food, water and poor command also being reported.^[318] By November, British intelligence said that recent weeks had "likely seen some of the highest Russian casualty rates of the war so far."^[319]

In mid-to-late October 2023, Ukrainian marines—partly guided by defecting Russian troops—crossed the

On 1 December 2023, Volodymyr Zelenskyy stated that the Ukrainian counter-offensive was not successful, citing slower than expected results.[322] Zelenskyy also stated that it will be easier for Ukraine to regain the Crimean peninsula than the Donbas region in the east of the country, because the Donbas is heavily militarised and there are frequent pro-Russian sentiments.^[323] In December 2023, multiple international media outlets described the Ukrainian counteroffensive as having failed to regain any significant amount of territory or meet any of its strategic objectives.^{[322][324][325]}

On 17 February 2024, Russia captured Avdiivka, a longtime stronghold for Ukraine that had been described as a "gateway" to nearby Donetsk.^{[326][327][328]} ABC News stated that Russia could use the development to boost morale with the war largely at a stalemate close to its second anniversary.^[329] Described by Forbes journalist David Axe as a pyrrhic Russian victory, the Russian 2nd and 41st Combined Arms Armies ended up with 16,000 men killed, tens of thousands wounded and around 700 vehicles lost before seizing the ruins of Avdiivka.^[330]

Ukraine's shortage of ammunition caused by political deadlock in the US Congress and a lack of production capacity in Europe contributed to the Ukrainian withdrawal from Avdiivka, and was "being felt across the front" according to Time. The shortage resulted in Ukraine having to ration its units to fire only 2,000 rounds per day, compared to an estimated 10,000 rounds fired daily by Russia.^[331]

On 10 May 2024, Russia began a renewed offensive in Kharkiv Oblast. Russia managed to capture a dozen villages, and Ukraine had evacuated more than 11,000 people from the region since the start of the offensive by 25 May. Ukraine said on 17 May that its forces had slowed the Russian advance, and by 25 May Zelenskyy said that Ukrainian forces had secured "combat control" of areas where Russian troops entered the northeastern Kharkiv region. Russian officials meanwhile said that they were "advancing in every direction" and that the goal was to create a "buffer zone" for embattled border regions.^[332][333] The White House said on 7 June that the offensive had stalled and was unlikely to advance further.^[334]

Following the Russian success in the battle of Avdiivka, their forces advanced northwest of it to form a salient, and by mid-April 2024 reached the settlement of

On 6 August 2024, Ukraine launched their first direct offensive into Russian territory, the largest of any pro-Ukrainian incursion since the invasion's inception, into the bordering Kursk Oblast.^[346] The main axis of the initial advance centred in the direction of the town of Sudzha, located 10 kilometres (6.2 mi) from the border,^[347] which was reported by President Zelenskyy to have been captured on 15 August.^[348] Ukraine, taking advantage of the lack of experienced units and defenses along the border with Kursk Oblast, was able to quickly seize territory in the opening days of the incursion.^[349] The incursion caused Russia to divert thousands of troops from occupied Ukrainian territory to counter the threat,^[350][351] though not from Donetsk Oblast.^[351] Russian troops continued advancing in eastern Ukraine, notably at a faster pace than prior to the Kursk offensive,^[352] including towards the strategically important city of Pokrovsk, where their number of forces had instead been increased.^{[353][354][355]}

In late August, Russian forces seized the city of Novohrodivka, southeast of Pokrovsk, bringing them within 8 kilometres of the city,^[352] while capturing Krasnohorivka^[356] and Ukrainsk,^[357] near Pokrovsk and west of Donetsk city, in early September.^[357] In late September, a Russian assault on the long-held city of Vuhledar began,^[358] leading to its fall on 1 October.^[359] Ukraine's 72nd Mechanised Brigade had defended the city for over two years, and said that the Russians had suffered ″numerous losses″ as they stormed the elevated city. Following the Russian capture, the city with a pre-war population of about 14,000 was described as a ″sprawling ruin″.^[360]

The supreme commanders-in-chief are the heads of state of the respective governments: President Vladimir Putin of Russia and President Volodymyr Zelenskyy of Ukraine. Putin has reportedly meddled in operational decisions, bypassing senior commanders and giving orders directly to brigade commanders.^[361]

US general Mark Milley said that Ukraine's top military commander in the war, commander-in-chief of the Armed Forces of Ukraine, General Valerii Zaluzhnyi, "has emerged as the military mind his country needed. His leadership enabled the Ukrainian armed forces to adapt quickly with battlefield initiative against the Russians."^[362] Russia began the invasion with no overall commander. The commanders of the four military districts were each responsible for their own offensives.^[363]

After initial setbacks, the commander of the Russian Southern Military District, Aleksandr Dvornikov, was placed in overall command on 8 April 2022,^[364] while still responsible for his own campaign. Russian forces benefited from the centralisation of command under Dvornikov,^[365] but continued failures to meet expectations in Moscow led to multiple changes in overall command:^[363]

• commander of the Eastern Military District Gennady Zhidko (Eastern Military District, 26 May – 8 October 2022)
• commander of the southern grouping of forces
  Sergei Surovikin
  (early October 2022 – 11 January 2023)
• commander-in-chief of the Russian Armed Forces
  Valerii Gerasimov
  (from 11 January 2023)

Russia has suffered a remarkably large number of casualties in the ranks of its officers, including 12 generals.^[366]

Aerial warfare began the first day of the invasion. Dozens of missile attacks were recorded across both eastern and western Ukraine,^[88][89] reaching as far west as Lviv.^[168]

By September 2022, the Ukrainian air force had shot down about 55 Russian warplanes.^[367] In mid-October, Russian forces launched missile strikes against Ukrainian infrastructure, intended to knock out energy facilities.^[368] By late November, hundreds of civilians had been killed or wounded in the attacks,^[369] and rolling blackouts had left millions without power.^[370]

In December 2022, drones launched from Ukraine allegedly carried out several attacks on

On 31 July 2022, Russian Navy Day commemorations were cancelled after a drone attack reportedly wounded several people at the Russian

Since fall of 2022, Russia has carried out waves of strikes on Ukrainian electrical and water systems.

The Russian cruiser Moskva, the flagship of the Black Sea Fleet, was, according to Ukrainian sources and a US senior official,^[414] hit on 13 April by two Ukrainian Neptune anti-ship cruise missiles, setting the ship afire. The Russian Defence Ministry said the warship had suffered serious damage from a munition explosion caused by a fire, and that its entire crew had been evacuated.^[415] Pentagon spokesman John Kirby reported on 14 April that satellite images showed that the Russian warship had suffered a sizeable explosion onboard but was heading to the east for expected repairs and refitting in Sevastopol.^[416] Later the same day, the Russian Ministry of Defence stated that the Moskva had sunk while under tow in rough weather.^[417] On 15 April, Reuters reported that Russia launched an apparent retaliatory missile strike against the missile factory Luch Design Bureau in Kyiv where the Neptune missiles used in the Moskva attack were manufactured and designed.^[418] On 5 May, a US official confirmed that the US gave "a range of intelligence" (including real-time battlefield targeting intelligence)^[419] to assist in the sinking of the Moskva.^[420]

On 1 June, Russian Foreign Minister Sergey Lavrov asserted that Ukraine's policy of mining its own harbours to impede Russian maritime aggression had contributed to the food export crisis, saying: "If Kyiv solves the problem of demining ports, the Russian Navy will ensure the unimpeded passage of ships with grain to the Mediterranean Sea."^[421] On 30 June 2022, Russia announced that it had withdrawn its troops from the island in a "gesture of goodwill."^[232] The withdrawal was later confirmed by Ukraine.^[422]

On 26 December 2023, Ukraine's air force attacked the Russian landing ship Novocherkassk docked in Feodosia. Ukraine said it was destroyed—unlikely to sail again. Russian authorities confirmed the attack, but not the loss, and said two attacking aircraft were destroyed. Independent analysts said the ship's loss could hamper future Russian attacks on Ukraine's coast.^{[423][424][425]} On 31 January 2024, Ukrainian sea drones struck the Russian Tarantul-class corvette Ivanovets in the Black Sea, causing the ship to sink.^[426][427] Two weeks later on 14 February, the same type of Ukrainian sea drones struck and sank the Russian landing ship Tsezar Kunikov.^[428][429]

Four days into the invasion, President Putin placed Russia's nuclear forces on high alert, raising fears that Russia could use tactical nuclear weapons against Ukraine, or a wider escalation of the conflict could occur.^[430] Putin alluded in April to the use of nuclear weapons, and Russian foreign minister Sergei Lavrov said there was a "real" danger of a World War III.^[431] On 14 April 2022, CIA director William Burns said that "potential desperation" in the face of defeat could encourage President Putin to use tactical nuclear weapons.^[432] In response to Russia's disregard of safety precautions during its occupation of the disabled former nuclear power plant at Chernobyl and its firing of missiles in the vicinity of the active Zaporizhzhia Nuclear Power Plant, Zelenskyy called on 26 April for an international discussion on Russia's use of nuclear resources, saying: "no one in the world can feel safe knowing how many nuclear facilities, nuclear weapons and related technologies the Russian state has ... If Russia has forgotten what Chernobyl is, it means that global control over Russia's nuclear facilities, and nuclear technology is needed."^[433]

In August 2022, shelling around Zaporizhzhia power plant became a crisis, prompting an emergency inspection by the IAEA. Ukraine described the crisis nuclear terrorism by Russia.^[434] On 19 September, President Biden warned of a "consequential response from the US" if Russia were to resort to using nuclear weapons in the conflict.^[435] Before the United Nations on 21 September Biden criticised Putin's nuclear sabre-rattling, calling Putin "overt, reckless and irresponsible... A nuclear war cannot be won and must never be fought."^[436] In March 2023, Putin announced plans to install Russian tactical nuclear weapons in Belarus.^[437]

Ukrainian civilians resisted the Russian invasion by volunteering for territorial defence units, making Molotov cocktails, donating food, building barriers like Czech hedgehogs,^[438] and helping to transport refugees.^[439] Responding to a call from Ukravtodor, Ukraine's transportation agency, civilians dismantled or altered road signs,^[440] constructed makeshift barriers, and blocked roadways.^[441] Social media reports showed spontaneous street protests against Russian forces in occupied settlements, often evolving into verbal altercations and physical standoffs with Russian troops.^[442] By the beginning of April, Ukrainian civilians began to organise as guerrillas, mostly in the wooded north and east of the country. The Ukrainian military announced plans for a large-scale guerrilla campaign to complement its conventional defence.^[443]

People physically blocked Russian military vehicles, sometimes forcing them to retreat.^[442][444] The Russian soldiers' response to unarmed civilian resistance varied from reluctance to engage the protesters,^[442] to firing into the air, to firing directly into crowds.^[445] There have been mass detentions of Ukrainian protesters, and Ukrainian media has reported forced disappearances, mock executions, hostage-taking, extrajudicial killings, and sexual violence perpetrated by the Russian military.^[446] To facilitate Ukrainian attacks, civilians reported Russian military positions via a Telegram chatbot and Diia, a Ukrainian government app previously used by citizens to upload official identity and medical documents. In response, Russian forces began destroying mobile phone network equipment, searching door-to-door for smartphones and computers, and in at least one case killed a civilian who had pictures of Russian tanks.^[447]

As of 21 May 2022, Zelenskyy indicated that Ukraine had 700,000 service members on active duty fighting the Russian invasion.^[448] Ukraine withdrew soldiers and military equipment back to Ukraine over the course of 2022 that had been deployed to United Nations peacekeeping missions like MONUSCO in the Democratic Republic of the Congo.^[449]

The invasion received widespread international condemnation from

According to the Economist Intelligence Unit in 2023, 31 percent of the world's population live in countries that are leaning towards or supportive of Russia, 30.7 percent live in neutral countries, and 36.2 percent live in countries that are against Russia in some way.[465]

By October 2022, three countries—Latvia, Lithuania and Estonia—had declared Russia a "terrorist state."^[466] On 1 August, Iceland became the first European country to close its embassy in Russia as a result of the invasion of Ukraine.^[467]

The invasion prompted Ukraine,^[468] Finland and Sweden to officially apply for NATO membership.^[469] Finland became a member of NATO on 4 April 2023,^[470] followed by Sweden on 7 March 2024.^[471]

A documentary film produced during the siege of Mariupol, 20 Days in Mariupol, won the Oscar for best documentary in 2024.^[472]

Foreign involvement in the invasion has been worldwide and extensive, with support ranging from military sales and aid, sanctions, and condemnation.^[473] Western and other countries imposed limited sanctions on Russia in the prelude to the invasion and applied new sanctions when the invasion began, intending to cripple the Russian economy;^[474] sanctions targeted individuals, banks, businesses, monetary exchanges, exports, and imports.^[473] From January 2022 to January 2024, $380 billion in aid to Ukraine was tracked by the Kiel Institute, including nearly $118 billion in direct military aid.^[475] NATO is coordinating and helping its member states provide military equipment and financial aid to the country.^[476]

The United States has provided the most military assistance to Ukraine,^[477] having committed over $46 billion from the start of the invasion to January 2024,^[475][e] though adopting a policy against sending troops.^[480] NATO members such as Germany reversed policies against providing offensive military aid to support Ukraine, and the European Union supplied lethal arms for the first time in its history, providing over €3 billion to Ukraine.^[481] Bulgaria has supplied more than €2 billion worth of arms and ammunition to Ukraine, including over one third of the ammunition needed in the early phase of the invasion and a plurality of needed fuel.^[482] In September 2023, Poland said it would cease sending arms to Ukraine after a dispute between the two countries over grain.^[483] Although India has maintained a neutral stance in the conflict, reports indicate that artillery shells produced by Indian manufacturers were sold to European countries and subsequently diverted to Ukraine. Indian officials have not intervened despite objections from Russia.^[484]

Belarus has allowed Russia to use its territory to stage part of the invasion, and to launch Russian missiles into Ukraine.^[485] Belarus airspace was used by Russia, including for radar early warning and control missions, until 2023, when a Russian Beriev A-50 surveillance plane was damaged by drones.^[486] Because of its active involvement, Belarus is considered a co-belligerent^[487][488] (but not a co-combatant^[489]) in this invasion, as contrasted to non-belligerent states, which have "a wide range of tools available to non-belligerent actors without reaching the threshold of warfighting".^[490]

In February 2024, a Reuters report indicated that Iran sent ballistic missiles to the Russian military.^[500] In April 2024, China was reported to have supplied Russia with geospatial intelligence, machine tools for tanks, and propellants for missiles.^[501] Russia imports sensitive electronics, machinery, auto parts, and defense equipment from India.^[502] Trade like oil sales has surged since 2022, boosting revenue for Russian state-owned companies. To bypass sanctions and manage its currency surplus, Russia pays in rupees, supporting both civilian and military needs.^[503][504]

Casualties

Further information: Casualties of the Russo-Ukrainian War § Russian invasion of Ukraine, and List of deaths during the Russian invasion of Ukraine

Russian and Ukrainian sources have both been said to inflate the casualty numbers for opposing forces and downplay their own losses for the sake of morale.^[505] Leaked US documents say that "under-reporting of casualties within the [Russian] system highlights the military's 'continuing reluctance' to convey bad news up the chain of command."^[506] Russian news outlets have largely stopped reporting the Russian death toll.^[507] Russia and Ukraine have admitted suffering "significant"^[508] and "considerable" losses, respectively.^[509][510]

The numbers of civilian and military deaths have been as always

iStories, citing sources close to the Kremlin, reported that more than 90,000 Russian soldiers had been killed, seriously wounded, or gone missing in Ukraine.^[513]

While combat deaths can be inferred from a variety of sources, including

Ukrainian Minister of Defence told CNN that he believed that tens of thousands of Ukrainians had died, adding that he hoped the total death toll was below 100,000.^[514] By the end of June 2024, about 20,000 Ukrainians had lost limbs.^[515] In the destroyed city of Mariupol alone, Ukrainian officials believe that at least 25,000 have been killed,^[516][517] and bodies were still being discovered in September 2022.^[518] The mayor said over 10,000 and possibly as many as 20,000 civilians died in the siege of Mariupol and that Russian forces had brought mobile cremation equipment with them when they entered the city.^[519][520] Researcher Dan Ciuriak from C. D. Howe Institute in August 2022 estimates the number of killed Mariupol civilians at 25,000,^[521] and an investigation by AP from the end of 2022 gives a number of up to 75,000 killed civilians in Mariupol area alone.^[522][523] AFP says that "a key gap in casualty counts is the lack of information from Russian-occupied places like the port city of Mariupol, where tens of thousands of civilians are believed to have died".^[524] According to a recent study by Human Rights Watch and two other organizations, there were at least 8,034 excess deaths in Mariupol between March 2022 and February 2023.^[525] The Office of the United Nations High Commissioner for Human Rights (OHCHR) reports similar issues and believed that the true civilian casualty numbers were significantly higher than it has been able to confirm.^[526]

In the Russian military during the invasion, Russia's ethnic minorities have been suffering disproportionately high casualties. In October 2022, the Russian regions with the highest death tolls were Dagestan, Tuva and Buryatia, all minority regions. In February 2024, six out of ten Russian regions with the highest mortality rates in Ukraine were located in Siberia and the far east, and ethnic minorities continuing outsized casualty rates prompted analysts to warn that the situation will lead to long-term destructive impacts on these communities.^{[527][528][529][530][531]} According to Western officials, about 1,200 Russian soldiers were killed or wounded in Ukraine every day in May and June 2024.^[532] Latvia-based news outlet Meduza estimated that up to 140,000 Russian soldiers had died in the war by the end of June 2024.^[533]

In August 2024,

Wall Street Journal reported that there were now one million Ukrainians and Russians who were killed or wounded.^[535] The Journal took note of how the number of casualties impacts the two countries' shrinking prewar populations.^[535]

Official and estimated numbers of

74th Guards from Kemerovo Oblast had surrendered, saying they were unaware that they had been brought to Ukraine and ordered to kill Ukrainians.^[557] Russia claimed to have captured 572 Ukrainian soldiers as of 2 March 2022,^[558] while Ukraine said it held 562 Russian soldiers as of 20 March.^[559] It also released one soldier for five of its own and exchanged another nine for the detained mayor of Melitopol.^[560]

On 24 March 2022, 10 Russian and 10 Ukrainian soldiers, as well as 11 Russians and 19 Ukrainian civilian sailors, were exchanged.^[561] On 1 April, 86 Ukrainian servicemen were exchanged^[562] for an unknown number of Russian troops.^[563] The Independent on 9 June 2022 cited an intelligence estimate of more than 5,600 Ukrainian soldiers captured, while the Russian servicemen held prisoner fell from 900 in April to 550 after several prisoner exchanges.

A 25 August 2022 report by the Humanitarian Research Lab of the

Olenivka prison, found two sites featuring disturbed earth consistent with "potential graves."^[564] Kaveh Khoshnood, a professor at the Yale School of Public Health, said: "Incommunicado detention of civilians is more than a violation of international humanitarian law—it represents a threat to the public health of those currently in the custody of Russia and its proxies." Conditions described by freed prisoners include exposure, insufficient access to sanitation, food and water, cramped conditions, electrical shocks and physical assault.^[564]

In late 2022, as Russian casualties exceeded 50,000, the Russian army introduced barrier troops. The U.K. defence ministry stated that these are units that threaten to shoot their own retreating soldiers in order to compel offensives. In March 2023, Russian soldiers filmed a video addressed to President Putin where they stated that after suffering casualties, they attempted to return to their headquarters but their superiors denied them evacuation. They stated that barrier troops were placed behind them threatening to "destroy them".^[565] In particular, Storm-Z units have been reported to be "kept in line" by barrier troops.^[566]

In March 2023, UN human rights commissioner Volker Türk reported that more than 90% of the Ukrainian POWs interviewed by his office, which could only include those who were released from Russia, said in Russia "they were tortured or ill-treated, notably in penitentiary facilities, including through so-called – it is an awful phrase – 'welcoming beatings' on their arrival, as well as frequent acts of torture throughout detention."^[567]

In April 2023, several videos started circulating on different websites purportedly showing Russian soldiers beheading Ukrainian soldiers.^[568] Zelenskyy compared Russian soldiers to "beasts" after the footage was circulated.^[569] Russian officials opened an investigation of the footage shortly thereafter.^[570]

War crimes and attacks on civilians

Main articles: War crimes in the Russian invasion of Ukraine and Attacks on civilians in the Russian invasion of Ukraine

war crimes in the 2022 Russian invasion of Ukraine, some notably involving Russian defence minister Sergei Shoigu.^[571]

During the invasion, the Russian military and authorities have been responsible for deliberate attacks against civilian targets^[572] (including strikes on hospitals and on the energy grid), massacres of civilians, abduction and torture of civilians, sexual violence,^[573] forced deportation of civilians, and torture and murder of Ukrainian prisoners of war. They have also carried out many indiscriminate attacks in densely populated areas, including with cluster bombs.^{[574][575][576]}

According to the Office of the United Nations High Commissioner for Human Rights (OHCHR), by December 2023, about 78% of confirmed civilian casualties had been killed in Ukrainian-controlled territory, while 21% had been killed in Russian-occupied territory.^[577]

Russian forces have reportedly used banned

chemical weapons at least 465 times during the war, usually as tear gas grenades.^[578] The use of tear gas is banned by international Chemical Weapons Convention and considered a chemical weapon if applied by military forces during warfare.^[579] On 6 April 2024, a Daily Telegraph investigation concluded that ″Russian troops are carrying out a systematic campaign of illegal chemical attacks against Ukrainian soldiers″.^[580]

In March 2024, the United Nations issued a report saying Russia may have executed more than 30 recently captured Ukrainian prisoners of war over the winter months. The Office of the United Nations High Commissioner for Human Rights verified three incidents in which Russian servicemen executed seven Ukrainian servicemen. According to the same report, 39 of 60 released Ukrainian prisoners of war also "disclosed that they had been subjected to sexual violence during their internment, including attempted rape, threats of rape and castration, beatings or the administration of electric shocks to genitals, and repeated forced nudity, including during interrogations and to check for tattoos."^[581]

Abduction of Ukrainian children

Main article: Child abductions in the Russo-Ukrainian War

In June 2024, an investigation by the Financial Times identified four Ukrainian children on a Russian government-linked adoption website that had been abducted from state care homes. The children's Ukrainian background was not mentioned. One child was shown with a new Russian name and age that differed from their Ukrainian documents, another was shown using a Russian version of their Ukrainian name. 17 additional matches identified by the Financial Times on the adoption website were also confirmed as Ukrainian children in a recent New York Times investigation. Ukrainian authorities estimate that nearly 20,000 Ukrainian children have been forcibly taken from occupied territories to Russia since the full-scale invasion began. Wayne Jordash, president of humanitarian law firm Global Rights Compliance, described forcibly transferring or deporting children as war crimes, adding that when done as part of a widespread or systematic attack on a civilian population, Russia is also committing crimes against humanity.^[582][583]

The ICC also issued arrest warrants for military officials Sergey Kobylash, Viktor Sokolov, Sergei Shoigu and Valery Gerasimov.^[591][592]

Impacts

Humanitarian impact

Main article:

Humanitarian impact of the Russian invasion of Ukraine

Further information: World food crises (2022–present)

The humanitarian impact of the invasion has been extensive and has included negative impacts on international food supplies and the

Minister of Culture called it cultural genocide.^[596] Deliberate destruction and looting of Ukrainian cultural heritage sites in this way is considered a war crime.^[597]

The Russian attacks on civilians, causing mass civilian casualties and displacement, have been characterised as genocide and democide.^{[18][19][20][21]} On 15 September 2023, a UN-mandated investigative body presented their findings that Russian occupiers had tortured Ukrainians so brutally that some of their victims died, and forced families to listen as they raped women next door.^[598][21] The commission has previously said that violations committed by Russian forces in Ukraine, including the use of torture, may constitute crimes against humanity.^[599]

A report by Physicians for Human Rights described Russian violence against the Ukrainian health care system as being a prominent feature of Russia's conduct during the war, documenting 707 attacks on Ukraine's health care system between 24 February and 31 December 2022. Such attacks are considered war crimes.^[600]

Refugee crisis

Main article:

2022–present Ukrainian refugee crisis

The war caused the largest refugee and humanitarian crisis in Europe since the Yugoslav Wars in the 1990s;^[601][602] the UN described it as the fastest growing such crisis since World War II.^[603] As Russia built up military forces along the Ukrainian border, many neighbouring governments and aid organisations prepared for a mass displacement event in the weeks before the invasion. In December 2021, the Ukrainian defence minister estimated that an invasion could force three to five million people to flee their homes.^[604]

In the first week of the invasion, the UN reported over a million refugees had fled Ukraine; this subsequently reached over eight million by 31 January 2023.^[605][606] On 20 May, NPR reported that, following a significant influx of foreign military equipment into Ukraine, a significant number of refugees are seeking to return to regions in Ukraine which are relatively isolated from the invasion front in southeastern Ukraine.^[607] However, by 3 May, another 8 million people were displaced inside Ukraine.^[608]

Most refugees were women, children, elderly, or disabled.^[609] Most male Ukrainian nationals aged 18 to 60 were denied exit from Ukraine as part of mandatory conscription,^[610] unless they were responsible for the financial support of three or more children, single fathers, or were the parent/guardian of children with disabilities.^[611] Many Ukrainian men, including teenagers, opted to remain in Ukraine voluntarily to join the resistance.^[612]

According to the UN High Commission for Refugees as of 13 May 2022, there were 3,315,711 refugees in Poland, 901,696 in Romania, 594,664 in Hungary, 461,742 in Moldova, 415,402 in Slovakia, and 27,308 in Belarus, while Russia reported it had received over 800,104 refugees.^[605] By 13 July 2022, over 390,000 Ukrainian refugees had arrived in the Czech Republic, where the average refugee was a woman accompanied by one child. These refugees were twice as likely to have a college degree as the Czech population as a whole.^[613] Turkey has been another significant destination, registering more than 58,000 Ukrainian refugees as of 22 March, and more than 58,000 as of 25 April.^[614] The EU invoked the Temporary Protection Directive for the first time in its history, granting Ukrainian refugees the right to live and work in the EU for up to three years.^[615] Britain has accepted 146,379 refugees, as well as extending the ability to remain in the UK for 3 years with broadly similar entitlements as the EU, three years residency and access to state welfare and services.^[616]

According to the

Chechen War of Independence.^[618] For instance, as of 8 April, Russia claimed to have evacuated about 121,000 Mariupol residents to Russia.^[618] Also, on 19 October, Russia announced the forced deportation of 60,000 civilians from areas around the line of contact in Kherson oblast.^[619] RIA Novosti and Ukrainian officials said that thousands were dispatched to various centres in cities in Russia and Russian-occupied Ukraine,^[620] from which people were sent to economically depressed regions of Russia.^[621] In April, Ukraine's National Security and Defence Council secretary Oleksiy Danilov said that Russia planned to build "concentration camps" for Ukrainians in western Siberia, and likely planned to force prisoners to build new cities in Siberia.^[622][h]

Long-term demographic effects

Ukrainian refugees

entering Romania, 5 March 2022

Both Russia and Ukraine faced the prospect of significant population decline even before the war, having among the lowest fertility rates worldwide and considerable emigration. It is the first time that two countries with an average age above 40 have gone to war against each other.^[624] Russia had a fighting-age (18- to 40-year-old) male population more than four times higher than Ukraine's and slightly higher birth rates, while the willingness to fight was more pronounced in Ukraine.^[625]

Several sources have pointed out that the war is considerably worsening Ukraine's demographic crisis, making significant shrinking very likely.

Vienna Institute for International Economic Studies stated that "regardless of how long the war lasts and whether or not there is further military escalation, Ukraine is unlikely to recover demographically from the consequences of the war. Even in 2040 it will have only about 35 million inhabitants, around 20% fewer than before the war (2021: 42.8 million) and the decline in the working-age population is likely to be the most severe and far-reaching." The study took different scenarios, from a "best case" (end of the war in 2023 without much further escalation) to a "worst case" (end of the war in 2025 with further escalation) into account. Flight from war affected especially the southern and eastern regions and especially educated women of child-bearing age and their children. With an estimate of more than 20% of refugees not returning, study author Maryna Tverdostup concluded that long-term shrinking will significantly impair the conditions for reconstruction.^[627]

The war in Ukraine and the associated emigration, lower

demographic crisis of Russia.^[628] Many commentators predict that the situation will be worse than during the 1990s.^[629] The UN is projecting that the decline that started in 2021 will continue, and if current demographic conditions persist, Russia's population would be 120 million in fifty years, a decline of about 17%.^[630][631]

Since February 2022, hundreds of thousands of

Russians have emigrated; estimates range from 370,000 to over 820,000. Combined with mobilisation, this possibly removed roughly half a million to one million working-age males from Russia's population.^[632] Studies report that this will have a demographic effect, especially in Russia, that lasts much longer than the conflict, and Putin's time in office.^[633]

According to BBC:[634]

They come from different walks of life. Some are journalists like us, but there are also IT experts, designers, artists, academics, lawyers, doctors, PR specialists, and linguists. Most are under 50. Many share western liberal values and hope Russia will be a democratic country one day. Some are LGBTQ+. Sociologists studying the current Russian emigration say there is evidence that those leaving are younger, better educated and wealthier than those staying. More often they are from bigger cities.

According to Johannes Wachs, "The exodus of skilled human capital, sometimes called

brain drain, out of Russia may have a significant effect on the course of the war and the Russian economy in the long run."^[635] According to a survey, around 15 percent of those who left returned to Russia, either permanently or to settle their affairs.^[636]

In November 2023, at the World Russian People's Council, Putin urged Russian women to have eight or more children amid increasing Russian casualties in the invasion.^[637]

In July 2024, Chief of the General Staff of the British Army Roland Walker said that with the current way of fighting, it would take Russia five years to control the four regions of Donetsk, Luhansk, Kherson and Zaporizhia that Russia claims as its own, and it would cost Russia from 1.5 to 1.8 million casualties.^[638] He said there are "no winners" in Russia's invasion, adding "it is an utter devastation for both sides and lost generations."^[639]

Environmental impact

Main article: Environmental impact of the Russian invasion of Ukraine

Based on a preliminary assessment, the war has inflicted

USD 51 billion in environmental damage in Ukraine; according to a report by the Yale School of the Environment, some 687,000 tons of petrochemicals have burned as a result of shelling, while nearly 1,600 tons of pollutants have leaked into bodies of water. Hazardous chemicals have contaminated around 70 acres of soil, and likely made agricultural activities temporarily impossible.^[640] Around 30% of Ukraine's land is now littered with explosives and more than 2.4 million hectares of forest have been damaged.^[641]

According to Netherlands-based peace organisation PAX, Russia's "deliberate targeting of industrial and energy infrastructure" has caused "severe" pollution, and the use of explosive weapons has left "millions of tonnes" of contaminated debris in cities and towns.[642] In early June 2023, the Kakhovka Dam, under Russian occupation, was damaged, causing flooding and triggering warnings of an "ecological disaster."^[643]

The Ukrainian government, international observers and journalists have described the damage as

Margot Wallstrom, Mary Robinson and Greta Thunberg) to discuss the environmental damage and how to prosecute it.^[646]

According to an investigation by NGL Media published in April 2024, Russia has completely destroyed over 60,000 hectares of Ukrainian forests. The investigation stated that long-term ecological consequences may include lowering of the groundwater level, reduction of biodiversity, worsening of air quality, fire outbreaks, and rivers and ponds drying up.[647]

Economic impact

Ukraine

Ukrainian Minister of Economic Development and Trade Yulia Svyrydenko announced that for 2022 Ukraine had a 30.4% loss in their GDP.^[648] The International Monetary Fund predicted that Ukraine's gross domestic product (GDP) would suffer a decrease from a minimum of 10% to a maximum of 35%;^[649] the European Bank for Reconstruction and Development also predicted that the invasion would cause a 20% decrease of Ukraine's GDP.^[650] However, the Ukrainian statistics service said that the GDP of Ukraine in 2023 grew by 5.3%.^[651]

Ukraine began issuing war bonds on March 1, 2022, and the following day the Ukrainian government announced that they had raised 6.14 billion hryvnias.^[652] A ban was placed in May 2022 by the European Commission on grain sales in the countries of: Bulgaria, Poland, Hungary, Romania and Slovakia with the only exception being if they were transiting through those countries with the ban being lifted in September 2023.^[653]

The war has caused a major humanitarian crisis in Ukraine: the United Nations Development Programme calculated in March 2022 that a prolonged conflict would cause 30% of the Ukrainian population to fall below the poverty line, while a further 62% would be at risk of also falling into poverty within a year.^[654]

Russia

The Russian economic ministry said that for 2022 the GDP contracted by 2.1%^[655] and for 2023 Russia's government said the GDP grew by 3.6%.^[656]

A price cap was placed on Russian oil by the Group of 7 (G7) at US$60 on December 5, 2022.^[657] The United States banned all imports of Russia oil on March 8, 2022.^[658] The European Union placed an embargo on oil products from Russia on February 5, 2023.^[657] Other countries that embargoed Russian oil were: Canada, United Kingdom and Australia.^[659] Russia itself issued a ban on foreign diesel sales starting on September 21, 2023, before being lifted on October 6.^[660]

On April 27, 2024, it was reported that Russia was planning increases in personal income taxes and corporate taxes to help pay for the war.^[661]

Peace efforts

Main article: Peace negotiations in the Russian invasion of Ukraine

Peace negotiations between Russia and Ukraine took place on 28 February, 3 March, and 7 March 2022, in the Gomel Region on the Belarus–Ukraine border, with further talks held on 10 March in Turkey and a fourth round of negotiations beginning 14 March.^[663]

On 13 July that year, Ukrainian foreign minister Dmytro Kuleba said that peace talks were frozen and Ukraine must first recover the lost territories in the east of the country before negotiations can begin.^[664] On 19 July, former Russian President and current Deputy head of the Russian Security Council Dmitry Medvedev, said: "Russia will achieve all its goals. There will be peace – on our terms."^[665]

In late September that year, after

Russian annexation of Donetsk, Kherson, Luhansk and Zaporizhzhia oblasts of Ukraine, Zelenskyy announced that Ukraine would not hold peace talks with Russia while Putin was president and in early October signed a decree to ban such talks.^[666][667] In late December that year, Putin's spokesperson Dmitry Peskov and Russian Foreign Minister Sergey Lavrov said that any peace plan could only proceed from Ukraine's recognition of Russia's sovereignty over the regions it annexed from Ukraine in September 2022.^{[668][669][670]} Ukraine counter proposal requires Moscow to return the occupied Ukrainian territories and pay war damages.^[671] In January 2023, Putin's spokesperson Peskov said that "there is currently no prospect for diplomatic means of settling the situation around Ukraine."^[672]

In May 2023, UN Secretary-General António Guterres said peace negotiations to end the Russo-Ukrainian War were "not possible at this moment", saying it was clear that Russia and Ukraine were "completely absorbed in this war" and each "convinced that they can win."^[673]

In June 2023, Ukrainian Defence Minister Oleksii Reznikov said that the peace plans presented by China, Brazil and Indonesia are attempts at mediation on behalf of Russia, and "they all currently want to be mediators on Russia's side. That's why this sort of mediation currently doesn't fit for us at all because they aren't impartial."^[674] He said that Ukraine was willing to accept China as a mediator only if Beijing could convince Russia to withdraw from all the territories it had occupied.^[675]

In December 2023, The New York Times reported that Putin has been signaling through intermediaries since at least September 2022 that "he is open to a ceasefire that freezes the fighting along the current lines." This has been received with skepticism by Ukrainians and their country's supporters, with criticism that it could be an insincere, opportunistic public relations ploy by Russia that would give it time to rebuild its weakened army before renewing the offensive.^[671][676] Such concerns have been raised since 2022.^[677][678] In May 2024, Kremlin sources told Reuters that Putin wanted to avoid unpopular steps such as further nationwide mobilization and increased war spending.^[679]
