Aleppo-based rebel groups reportedly unite behind Ahrar al Sham’s former top leader
Several rebel groups in Syria’s Aleppo province have united under the leadership of Hashem al Sheikh, who was the emir of Ahrar al Sham from September 2014 to September 2015. The alliance doesn’t include Al Nusrah Front, al Qaeda’s official branch in Syria, but its constituents will almost certainly continue to cooperate with al Qaeda’s men.
