Over 30 Syrian opposition fighters killed in an IS bus suicide blast

Over 30 Syrian rebel fighters are reported to have been killed in a suicide bombing on a bus near the Atmeh border crossing with Turkey.

Sources told Turkish media that the attacker detonated an explosive vest on the bus at the entrance to a camp for displaced people late on Sunday.

The death toll was likely to rise, activists monitoring the conflict said.

A news agency linked to the jihadist group Islamic State reported that one of its militants was behind the attack.

Syrian opposition Orient TV reported that those killed were from “numerous” rebel factions, all of which are opposed to IS.
