The United States said it was “deeply troubled” Wednesday after the world’s chemical watchdog confirmed the systematic use of chlorine as a weapon in war-torn Syria.

President Bashar al-Assad’s regime and the rebels fighting it have both accused the other of using chemical agents, including chlorine, in the bloody uprising that began in March 2011.

Damascus promised to hand over all its chemical arms, and tonnes of chemical agents have been destroyed by international monitors.
