Syria's commitment to a ceasefire and pledges to allow aid deliveries are slipping, putting the peace process on a more fragile footing, US Ambassador Samantha Power said Tuesday, according to AFP.
UN envoy Staffan de Mistura briefed the Security Council during a closed-door meeting, on the eve of a resumption in Geneva of talks aimed at ending the five-year war.
Power told reporters after the meeting that Russia must put pressure on its Syrian ally to "get the regime back with the program."
"Right now, there are signs that this is slipping and it is a much more delicate environment for De Mistura to convene political talks," said Power.
