In recent days, unacceptable violations of Syria’s cessation of hostilities and the rules of international law have threatened to doom the initiative in its entirety. Numerous strikes on civilians, including several targeting medical facilities and rescue workers, have killed dozens. This must stop now.
Just weeks ago, the US and Russia helped secure the CoH, providing a glimpse of what a respite from violence means for people in Syria. Fewer people died in the first month of Syria’s ceasefire than at almost any other time since the war began. For many, it was the first time in years that they could walk the streets without fear. This was a first glimpse of hope. That hope that now hangs in the balance. Syria is yet again on the brink of humanitarian disaster and the need for action is urgent.

President Obama and President Putin: these atrocities are happening on your watch. Please heed the call of the UN Special Envoy to Syria to take urgent steps to rescue Syria's cessation of hostilities and end attacks on civilians. Please act now to keep hope alive for Syrians.
