United States Assessment of the Assad Regime’s Chemical Weapons Use 

Key Takeaway
The United States assesses with confidence that the Syrian regime used chemical weapons in the
eastern Damascus suburb of Duma on April 7, 2018, killing dozens of men, women, and
children, and severely injuring hundreds more. This conclusion is based on descriptions of the
attack in multiple media sources, the reported symptoms experienced by victims, videos and
images showing two assessed barrel bombs from the attack, and reliable information indicating
coordination between Syrian military officials before the attack. A significant body of
information points to the regime using chlorine in its bombardment of Duma, while some
additional information points to the regime also using the nerve agent sarin. This is not an
isolated incident—the Syrian regime has a clear history of using chemical weapons even after
pledging that it had given up its chemical weapons program.
