TOPSHOT - Syrian residents of the newly retaken eastern neighbourhoods of Aleppo walk through the Bab al-Hadid district as they go back home under supervision of the Syrian pro-government forces on December 8, 2016. President Bashar al-Assad said victory for his forces in Aleppo would be a "huge step" in ending Syria's war, as government troops battled to retake more rebel ground. Regime forces have retaken about 80 percent of former rebel territory in Aleppo since launching an all-out offensive three weeks ago to recapture Syria's second city. / AFP / GEORGE OURFALIAN (Photo credit should read GEORGE OURFALIAN/AFP/Getty Images)
