ALEPPO, Syria (AP) — The street looks as if it was hit by an earthquake and the bombed-out building in a former rebel-held northeastern neighborhood of Aleppo is deserted — except for the second-floor apartment where Abdul-Hamid Khatib and his family are staying. The apartment windows are covered with nylon sheets and a hole caused by a shell in the sitting room wall is closed with a piece of metal, pierced by the exhaust pipe for the wood-burning heater. Khatib and his family are the only occupants of the six-story building and they keep its main gate locked with a metal chain, fearing looters. The eldest son Mohammed was killed in the bombardment of east Aleppo in 2013 and their granddaughter Hasnaa, 4, was killed a year later by a bullet as she played on the balcony of her parents' apartment. Since rebels fighting to topple President Bashar Assad stormed east Aleppo in July 2012, the family had to leave the house twice to move to safer areas, before returning back home. In late December, government forces and their allies took control of east Aleppo, bringing the whole city under state control in the biggest victory for Assad since the country's conflict began in March 2011.
