Death toll rises to 158 in chemical warehouse explosions in Chinese port of Tianjin

Authorities say the death toll has risen to 158 in massive warehouse explosions in the Chinese port of Tianjin. Some 15 people remain missing.

The Tianjin government's official microblog said the confirmed toll rose from 150 last week, but it wasn't clear how the tally increased. Calls to the city's information center rang unanswered.

Among the dead were 94 firefighters, 11 policemen and 53 civilians.

The Aug. 12 series of blasts at warehouses storing hazardous chemicals was one of China's worst industrial accidents in years, and has exposed lax enforcement of safety regulations.

Authorities have detained 12 company officials, as well as 11 government officials in an investigation.
