A massive explosion late Wednesday rocked the Chinese port city of Tianjin, killing at least 17 people, including nine firefighters, and injuring hundreds of others.

The death toll came from China's state-run People's Daily. The Associated Press also reported 17 people dead, citing police officials.

People's Daily attributed the explosion to “combustible and explosive goods” at the city’s container terminal, and said the company where the blast occurred “handles the transport of hazardous goods.” It quoted the Tianjin Public Security Bureau for the information.

State-run media reported the impact of the blast could be felt miles away. People's Daily reported that China’s Earthquake Network Center measured two blasts, 30 seconds apart.

CCTV-America, the U.S. arm of the Chinese state-run broadcaster, added:

The National Business Daily newspaper also reported that two firefighters battling the blaze are missing and six are slightly wounded. Six fire brigades are on the scene and the fire is nearly out. The newspaper also reported that 300-400 people are wounded.

Xinhua, the official news agency, said the fire caused by the explosion was “under control.” The Guardian subsequently reported that firefighting efforts had been temporarily called off due to safety fears over potentially toxic chemicals in the warehouses.
