The US envoy to the UN has condemned the reported cease-fire violations in southern Syria.
In a statement Friday, Ambassador Nikki Haley said "The Syrian regime's violations of the ceasefire in southwest Syria need to stop. We expect Russia ... to use the influence it has to stop the Syrian regime's violations and any further destabilizing actions in the southwest and throughout Syria.
"Russia will ultimately bear responsibility for any further escalations in Syria," added Haley.
The statement said the US had negotiated southwest area de-escalation ceasefire with Russia "to de-escalate the conflict, save lives, create conditions for the safe and voluntary return of the displaced, and ultimately to move toward a peaceful political settlement in accordance with UN Security Council Resolution 2254."
