Al-Qaeda-linked rebels have allegedly pulled out of strategic areas in northern Syria after clashes with another Islamist opposition force, according to Reuters. 
The Islamic State of Iraq and the Levant (ISIL)  pulled out of its stronghold Al Dana in Idlib Sunday after clashing with other Islamist rebel groups, including the Al Nusra Front as well as secular rebel groups such as the Western-backed Free Syrian Army. ISIL also reportedly pulled out of Atma, a town located on a key rebel supply route. No clashes predecessed ISIL's withdraw from Atma.
"The Islamic State is pulling out without a fight. Its fighters are taking their weapons and heavy guns. They appear to be heading in the direction of Aleppo," an activist told Reuters.
The area has been key in the fight against the regime as it has been a main supply route for various rebel groups.
