14:59 update: Tweep @multiple1902@ is now heading out live to the scene of the blast.

First, tragedy:

A powerful blast likely caused by a gas leak rocked a plastics factory in eastern China on Wednesday, killing at least six people and injuring hundreds, state media reported.

The explosion happened about 10 a.m. in downtown Nanjing, the capital of’ Jiangsu province in eastern China, the official Xinhua News Agency reported.

Xinhua said six people were reported as dead at hospitals treating victims of the blast, and that buildings and vehicles with 100 yards of the blast were badly damaged.

And this (typical here in China):

Officials who answered telephone calls at the Nanjing health department and city government would not comment. An official from the local Communist Propaganda Department said a statement would be released later.

Apparently, according to the Chinese-language twitterverse, the head of the Communist Propaganda Department, Ye Hao (叶皓) got pretty upset when live TV crews poured in — in no time. Media were treated to what could well be yet another 2010 catchphrase on the Chinese Interwebs: Who let you broadcast it live!? (谁让你做直播的)

There’s also footage of the explosion, as well as photos. Needless to say, there’s an increasing number of tweets coming out of this as even a few of the Twitterati head to the scene, live.
