Syrian rebels battle each other north of Aleppo

BEIRUT - Syrian insurgents clashed in a town near the Turkish border on Monday as inter-rebel tensions spilled over, playing to President Bashar Assad's advantage with the government tightening its grip on rebel-held eastern Aleppo.
The confrontation in Azaz pitted a prominent Free Syrian Army (FSA) rebel group, the Levant Front, against factions that also fight under the FSA banner and the Islamist Ahrar al-Sham, sources on both sides and a group that reports on the war said.
The Syrian Observatory for Human Rights said headquarters and checkpoints held by the Levant Front had been seized in the fighting, which a Levant Front official said had forced the group to withdraw some fighters from a battle with Islamic State in the nearby city of al-Bab.
The fighting in Azaz, some 60 km (35 miles) north of Aleppo, also prompted Turkey, which backs a number of FSA rebel groups, to close the border crossing at Oncupinar. Adjacent to Bab al-Salam in Syria, it is a major conduit for traffic between opposition-held northern Syria and Turkey.
