Syrian rebels and residents of Aleppo struggled Saturday to contain a huge fire that destroyed parts of the city's medieval souks, or markets, following raging battles between government troops and opposition fighters there, activists said. Some described the overnight blaze as the worst blow yet to a historic district that helped make the heart of Aleppo, Syria's largest city and commercial hub, a UNESCO world heritage site.
