Six Syrian rebel groups call for ceasefire between warring rebel factions

The two major factions battling in the north are al-Qaeda’s Islamic State in Iraq and the Levant on one side,and the Western-backed Free Syrian Army’s Northern Storm Brigade on the other.

The infighting has become an increasingly prominent component in Syria’s conflict,now in its third year.

The statement was reported by the Britain-based Syrian Observatory for Human Rights,which documents the civil war and also rebel-on-rebel fighting.

Among those that signed the appeal are the Islamic Army and the Tawheed Brigade.
