DEBALTSEVE, Ukraine (Reuters) - Sergei, a tired-looking man in his twenties, loads his bike with a tin of coal, the only thing of value he has salvaged from his destroyed house - now a rubble of grey bricks after Ukrainian forces and pro-Russian rebels fought over his hometown.
Moscow-backed separatists stormed the eastern Ukrainian town of Debaltseve nearly two weeks ago, in one of the most dramatic advances by the rebels since the start of the 10-month-old war.
