ALEPPO, Syria — A lonesome darkness hangs over this war-ravaged city. It is as if time has gone hundreds of years back, to an era when electricity was not yet discovered. Near the rubble of destroyed buildings, among dozens of desolate buildings, light emanates from some balconies that are still inhabited, which gives you the feeling that there is still life here. You are in Aleppo, the economic capital and second-largest city in Syria.
