An explosion ripped through a warehouse storing "dangerous goods" in north China's Tianjin City late Wednesday night, injuring at least 50 people.

The blast started at around 11:30 p.m. Wednesday in the Binhai New Area. The fireballs erupted from it then ignited further explosions in companies nearby.

The shockwaves were felt kilometers away, with some residents claiming their window glass and fish tanks shattered. People in neighborhoods nearby said flames lit up the sky and the blasts with big noises blew up dust of dozens of meters high.

Lu Yun, head of the nearby Taida Hospital, said they have received more than 50 wounded people, and more are coming. The injuries were mainly from broken glass or stones. Some of the injuries are serious.
