BEIRUT– Eighteen fighters were killed in a car bomb blast that hit a Syrian insurgent group in the southern province of Quneitra on Wednesday, a monitoring group reported, and a rebel source said the attack was likely carried out by hardline Islamists.
The Syrian Observatory for Human Rights said the explosion took place in the village of al-Isha, hitting a base belonging to Jabhat Thuwwar Souria, a Free Syrian Army group.
