Video: Tianjin Blast kills 50, watch as it happens.

Huge, fiery blasts at a warehouse for hazardous chemicals killed at least 50 people and turned nearby buildings into skeletal shells in the Chinese port of Tianjin, raising questions on Thursday about whether the materials had been properly stored.Hundreds of people were injured in the explosions shortly before midnight on Wednesday, which sent out massive fireballs that turned the night sky into day and shattered windows several kilometers away. Twelve of the dead were from among the more than 1 000 firefighters sent to the mostly industrial zone to fight the ensuing blaze.
"I thought it was an earthquake, so I rushed downstairs without my shoes on," said Tianjin resident Zhang Siyu, whose home is several kilometers from the blast site. "Only once I was outside did I realise it was an explosion. There was the huge fireball in the sky with thick clouds. Everybody could see it."
Zhang said she could see wounded people weeping. She said she did not see anyone who had been killed, but "I could feel death."
The municipal government in Tianjin, a key port and petrochemical processing hub about 120km east of Beijing, said 701 people were injured, including 71 in serious condition. It gave no figure for the missing.
