Ахрар аш-Шам
In late November 2015, there were clashes between the Army of Revolutionaries, supported by the YPG, and the FSA-dominated Mare' Operations Room in the northern Aleppo Governorate, backed by Ahrar ash-Sham and the al-Nusra Front. However, both the YPG and al-Nusra denied involvement in the conflict.
