Gas poisoning kills four in China

Beijing: Four workers were killed by an unknown gas when they were repairing heating pipelines in north China`s Inner Mongolia autonomous region, the local work safety watchdog said Wednesday.
The accident happened around 11 a.m. when two workers cut off a pipe in a well and were poisoned by the gas which leaked out of the pipe at Ulan Qab city`s Jining New District, Xinhua reported.

Another two workers who entered the well to rescue them were also poisoned and died later despite medical efforts, said a statement from the watchdog.

The cause of the accident is being probed.
