Syria war: Air strikes on market 'kill more than 50'
At least 53 people are reported to have been killed in air strikes in Syria.
The Syrian Observatory for Human Rights war monitoring group said on Monday that air strikes on a market had killed at least 50 people in a rebel-held area of northwest Syria.
Three air raids hit the town of Atareb, west of the city of Aleppo, the Britain-based observatory said. It said the death toll was likely to rise.
Atareb is inside what is known as a “de-escalation” zone under a deal agreed between Turkey, Russia and Iran to reduce violence in the area.
Footage on social media shows rubble on the streets and frightened people tending to and carrying away those injured in the attack.
It is not clear who carried out the strike.
