A United Nations envoy has warned Syria’s civil war has not yet ended, despite the removal of President Bashar al-Assad by opposition fighters. On Tuesday, U.N. Syria envoy Geir Pedersen told the U.N. Security Council that Turkish-backed armed groups are continuing to battle Kurdish groups for control of several areas of northern Syria. Meanwhile, the U.S. State Department said it had brokered an extension of a ceasefire deal between Turkey and the U.S.-backed Kurdish Syrian forces around the northern Syrian city of Manbij.
