Syrian Civil War

The Jaysh Halab (Arabic: جيش حلب‎, lit. 'Army of Aleppo'‎) was a coalition of Syrian rebel groups based in rebel-held areas inside the city of Aleppo, Syria. The coalition was created by Hashim al-Sheikh, the former general commander of Ahrar ash-Sham with the intent of unifying various rebel groups in Aleppo. After the announcement, nothing was heard of the group until December 2016.

The joint operations room consisted of both Sunni Islamist and Salafist factions and some Free Syrian Army groups. On its formation in 6 February 2016, the former Ahrar ash-Sham commander issued an ultimatum that ordered 15 rebel factions to join the group within 72 hours.

On 1 December 2016, during the Aleppo offensive, all rebel groups in southeastern Aleppo reportedly merged into the coalition replacing Fatah Halab in southeastern Aleppo. A new commander, Abu Abdul Rahman Noor was named. On 9 December a new emir was named, Abu Ashida'a
