Rebel fighters from the Jaish al-Fatah (or Army of Conquest) brigades gather in position on November 3, 2016, at an entrance to Aleppo, in the southwestern frontline near the neighbourhood of Dahiyet al-Assad, during a rebel offensive to break a three-month siege of the opposition-held east of Syria's second city. Syrian rebels launched a new wave of car bombs and rockets on Aleppo's western districts, redoubling their efforts to break the government's three-month siege of the city.
