The head of the opposition Syrian National Coalition called for a suspension of the US-led air campaign against Islamic State in Syria while reports of dozens of civilian deaths from air strikes around the northern city of Manbij are investigated.
Air strikes on rebel-held neighbourhoods in Syria's second city Aleppo on Friday killed at least 18 civilians and wounded more than a dozen, the local civil defence told AFP.
Syrian troops on Sunday seized the key Islamic State group bastion of Al-Qaryatain, dealing the jihadists a new blow in the country's centre a week after expelling them from Palmyra, state television said.
