Coal mine accident kills 21 in China

A state news agency said 21 workers are dead after an accident at a coal mine in northern China.

Xinhua News Agency said four miners were saved by rescuers, while seven escaped on their own from the Wujiu coal mine outside Datong city in Shanxi province.

The report said a preliminary probe into yesterday’s accident showed it was probably caused by an explosion.

China’s mines are the world’s deadliest, with explosions, cave-ins and floods killing nearly 3,800 people last year.
