A car bomb exploded at a checkpoint manned by Turkey-backed opposition fighters in northeast Syria killing at least four people Thursday, local officials and Syrian opposition activists said.
The governor's office of Turkey's southern Sanliurfa region said in a statement on its website that one gendarmerie corporal and three local security personnel were killed in the attack.
It blamed Kurdish militants for the blast on the road leading to the Syrian town of Ras al-Ayn Thursday afternoon.
