Several chemical attacks took place at Douma on 7 April 2018.
The French services analysed the testimonies, photos and videos that spontaneously appeared on specialized websites, in the press and on social media in the hours and days following the attack. Testimonies obtained by the French services were also analysed. After examining the videos and images of victims published online, they were able to conclude with a high degree of confidence that the vast majority are recent and not fabricated. The spontaneous circulation of these images across all social networks confirms that they were not video montages or recycled images. Lastly, some of the entities that published this information are generally considered reliable.
French experts analysed the symptoms identifiable in the images and videos that were made public. These images and videos were taken either in enclosed areas in a building where around 15 people died, or in local hospitals that received contaminated patients. These symptoms can be described as follows (cf. annexed images):
Suffocation, asphyxia or breathing difficulties,
Mentions of a strong chlorine odour and presence of green smoke in affected areas,
Hypersalivation and hypersecretions (particularly oral and nasal),
Skin burns and corneal burns.
No deaths from mechanical injuries were visible. All of these symptoms are characteristic of a chemical weapons attack, particularly choking agents and organophosphorus agents or hydrocyanic acid. Furthermore, the apparent use of bronchodilators by the medical services observed in videos reinforces the hypothesis of intoxication by choking agents.
On the basis of this overall assessment and on the intelligence collected by our services, and in the absence to date of chemical samples analysed by our own laboratories, France therefore considers (i) that, beyond possible doubt, a chemical attack was carried out against civilians at Douma on 7 April 2018; and (ii) that there is no plausible scenario other than that of an attack by Syrian armed forces as part of a wider offensive in the Eastern Ghouta enclave. The Syrian armed and security forces are also considered to be responsible for other actions in the region as part of this same offensive in 2017 and 2018. Russia has undeniably provided active military support to the operations to seize back Ghouta. It has, moreover, provided constant political cover to the Syrian regime over the employment of chemical weapons, both at the UN Security Council and at the OPCW, despite conclusions to the contrary by the JIM.
