Fatah Halab (Arabic: فتح حلب, lit. 'Conquest of Aleppo'), or Aleppo Conquest, was a joint operations room of Syrian rebel factions operating in and around Aleppo, Syria. Succeeding the Aleppo Liberation operations room, its establishment was announced on 26 April 2015. It stated that its aim was to conquer Aleppo City from Syrian government forces.
In an October 2015 publication, the Washington D.C.-based Institute for the Study of War considered Aleppo Conquest as one of the "powerbrokers" in Aleppo Governorate, being both "anti-regime" and "anti-ISIS."
Since the inter-rebel conflicts, defections and mergers which started in December 2016, Fatah Halab has become largely defunct.
The operations room included both US-backed groups and Sunni Islamist groups. It included some groups which also participated in the Sunni Islamist Ansar al-Sharia operations room, but not others, such as al-Nusra Front. Previously al-Nusra coordinated with other groups through the Aleppo Operations Room.
