BEIRUT - Activists say that Syrian rebels have seized a compound held by al-Qaida-linked fighters in a northern town, in some of the most serious infighting between rebels battling President Bashar Assad.
The Britain-based Syrian Observatory for Human Rights said that the rebels seized the compound in Manbij belonging to the Islamic State in Iraq and the Levant on Sunday.
The Observatory, which obtains its information from a network of activists in Syria, said ISIL fighters also used car bombs for the first time to defend its territory.
Fighting between the ISIL and other Syrian rebels began Friday after residents accused them of killing a popular doctor.
The infighting underscores how complicated the uprising against Assad has become with the uprising in its third year.
