ALEPPO, Syria – Entire neighborhoods of Syria's largest city bear battle scars: buildings toppled by government shells, charred tanks blown up by rebels and trash-strewn no-man's lands where neither side has full control after nearly a month of deadly street battles.

Ruin and tragedy can come in an instant. On Friday, a government fighter jet blasted the top three floors of a five-story apartment building, killing a mother, father and their three boys. Buried in the rubble was a newlywed couple who moved in on their wedding night two months ago.

Rebel fighters crawled through collapsed debris and punched holes in walls while searching the building for Mohammed Ezzo, his wife Ola, and anyone else that might be there. Across the street, the groom's father gazed at the building and wailed into his hands.
