China Mine Blast Traps 50

Chinese officials say a gas explosion has trapped at least 50 coal miners deep underground.

Officials say the blast occurred before dawn Thursday at a mine in northern Hebei province.

The condition of the miners is not immediately known.

The latest accident in China's notoriously dangerous mines comes one week after an accidental explosion killed 21 miners in Sichuan province in southwestern China.
