証拠 > 証人陳述書と被害者の症状

Syrian human rights lawyer Razan Zaitouneh, who was present in Eastern Ghouta, stated, "Hours [after the shelling], we started to visit the medical points in Ghouta to where injured were removed, and we couldn't believe our eyes. I haven't seen such death in my whole life. People were lying on the ground in hallways, on roadsides, in hundreds." Several medics working in Ghouta reported the administration of large quantities of atropine, a common antidote for nerve agent toxicity, to treat victims.
Doctors Without Borders said the three hospitals it supports in Eastern Ghouta reported receiving roughly 3,600 patients with "neurotoxic symptoms" over less than three hours during the early morning of 21 August. Of those, 355 died. The Local Coordination Committees of Syria claimed that of the 1,338 victims, 1,000 were in Zamalka, of which 600 bodies were transferred to medical points in other towns and 400 remained at a Zamalka medical center. Some of the fatalities were rebel fighters. The deadliness of the attack is believed to have been increased due to civilians reacting to the chemical attack as if it was typical government bombardment. For conventional artillery and rocket attacks, residents usually went to the basements of buildings, where in this case the heavier-than-air sarin sank into these below-ground, poorly ventilated areas. Some of the victims died while sleeping.
Abu Omar of the Free Syrian Army told The Guardian that the rockets involved in the attack were unusual because "you could hear the sound of the rocket in the air but you could not hear any sound of explosion" and no obvious damage to buildings occurred. Human Rights Watch's witnesses reported "symptoms and delivery methods consistent with the use of chemical nerve agents." Activists and local residents contacted by The Guardian said that "the remains of 20 rockets [thought to have been carrying neurotoxic gas] were found in the affected areas. Many [remained] mostly intact, suggesting that they did not detonate on impact and potentially dispersed gas before hitting the ground."
Doctors Without Borders also reported seeing a "large number of victims arriving with symptoms including convulsions, excessive saliva, pinpoint pupils, blurred vision and respiratory distress." Symptoms reported by Ghouta residents and doctors to Human Rights Watch included "suffocation, muscle spasms and frothing at the mouth."
Witness statements to The Guardian about symptoms included "people who were sleeping in their homes [who] died in their beds," headaches and nausea, "foam coming out of [victims'] mouths and noses," a "smell something like vinegar and rotten eggs," suffocation, "bodies [that] were turning blue," a "smell like cooking gas" and redness and itching of the eyes. Richard Spencer of The Telegraph summarised witness statements, stating, "The poison ... may have killed hundreds, but it has left twitching, fainting, confused but compelling survivors."
On 22 August, the Center for Documentation of Violations in Syria published numerous testimonies. It summarised doctors' and paramedics' descriptions of the symptoms as "vomiting, foamy salivation, severe agitation, [pinpoint] pupils, redness of the eyes, dyspnea, neurological convulsions, respiratory and heart failure, blood out of the nose and mouth and, in some cases, hallucinations and memory loss".
