China battles fires, contamination at chemical blast site

TIANJIN, China, Aug 14 (AFP): Chinese authorities struggled Friday to extinguish fires and identify dangerous chemicals at a devastated industrial site, two days after giant explosions killed dozens and left residents in fear of being cloaked in a toxic cloud.
Officials in the northern port city of Tianjin, where the blasts killed at least 56 people and injured more than 700, told a news conference they did not yet know what materials were at the hazardous goods storage facility that exploded, or the cause of the blast.
