Rebels 'battling al-Qaida fighters'
Syrian rebels have seized a compound held by al-Qaida-linked fighters in a northern town, amid some of the most serious infighting between rebels battling president Bashar Assad, according to reports.
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 (ISIL).
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 on Friday after residents accused them of killing a popular doctor.
The infighting underscores how complicated the uprising against Mr Assad's regime has become as the uprising enters its third year.
