(New York, February 13, 2017) – Syrian government forces conducted coordinated chemical attacks in opposition-controlled parts of Aleppo during the final month of the battle for the city, Human Rights Watch said today. 

Through phone and in-person interviews with witnesses and analysis of video footage, photographs, and posts on social media, Human Rights Watch documented government helicopters dropping chlorine in residential areas on at least eight occasions between November 17 and December 13, 2016. The attacks, some of which included multiple munitions, killed at least nine civilians, including four children, and injured around 200.
