Al Qaeda’s rebranded guerrilla army in Syria is fighting alongside other jihadists, Islamists and Free Syrian Army-branded rebels in an offensive intended to break the Assad regime’s siege of Aleppo. Most of the participating groups belong to two coalitions: Jaysh al Fath (“Army of Conquest”) and Fatah Halab (“Aleppo Conquest”). These same two alliances tried and failed to break the siege earlier this year.
