Tianjin (China), Aug. 13 (Reuters): Two huge explosions tore through an industrial area where toxic chemicals and gas were stored in the northeast Chinese port city of Tianjin, killing at least 50.

At least 700 people were injured, more than 71 seriously, the Tianjin government said on its Weibo microblog.

Vast areas of the port were devastated, crumpled shipping containers were thrown around like match sticks, hundreds of new cars were torched and port buildings left as burnt-out shells, witnesses said. "I was sleeping when our windows and doors suddenly shook as we heard explosions outside," Guan Xiang, who lives 7km away from the explosion site, said.
