On 25 August 2013, fighting occurred between Syrian Army soldiers and opposition fighters in Ashrafiyat Sahnaya. At around 18:00, the rebels started to throw objects with a catapult. Around 20:00 an object was thrown at a group of five Syrian Army soldiers. The object landed 10–15 meters from them, and released a badly smelling gas. The five soldiers were immediately taken to a field medical point where they were treated with injections, eye droplets and oxygen. They were then transported to Martyr Yusuf Al Azmah Military Hospital for emergency care, where medical personnel took blood samples of them. The blood samples tested positive for sarin.[3]: 17–18, 71–78 Five days after the incident, the victims were interviewed by the United Nations Mission to Investigate Alleged Uses of Chemical Weapons in the Syrian Arab Republic.[3]: 73
