FOUR miners trapped underground in a coal pit were named last night as rescue efforts continued.

US authorities said crews found the bodies of four miners missing nearly a week since an explosion at a coal mine, bringing the death toll to 29.

Drilling was being carried out today in a bid to release toxic gas from a mine where four people were feared trapped following an explosion in which 25 were killed.

Twenty-five workers have been killed and at least four are unaccounted for after an explosion rocked a remote coal mine in the US.
