At least 21 people have been killed and dozens more injured, according to the Aleppo Media Center activist group.


A car bomb explosion ripped through the busy centre of a rebel-held town near Syria’s border with Turkey caused deaths and wounded dozens on Saturday, a monitor, local resident and rebel group said.

Dozens more had severe injuries, the Britain-based war monitor said.
