Four Colombian Miners Die In Coal Mine Accident

`At the moment, they`re carrying out a rescue operation to retrieve the bodies,` said Adriana Cuevas, an emergency official.

Four coal miners were killed and two injured on Saturday in an accident at a mine in central Colombia, one of the country's worst such incidents in months, an official said.

"At the moment, they're carrying out a rescue operation to retrieve the bodies but by Monday or Tuesday we should have more details about the cause," said Adriana Cuevas, an emergency official.

She said an explosion of gases was the likely cause of the accident at the small mine in the province of Boyaca.

Last August, a methane explosion killed eight miners in an illegally operated coal mine in neighboring Cundinamarca province.

Colombia is among the world's top five coal suppliers.
