Jaysh al-Ahrar (Arabic: جيش الأحرار, lit. 'Army of the Free'), is an armed Salafi Islamist rebel group in northwestern Syria that originated as a clique composed of 16 units in Ahrar al-Sham that opposed involvement in Operation Euphrates Shield, after a fatwa was released by religious clerics in Jabhat Fatah al-Sham, which led to the group's separation from Ahrar al-Sham.
