From the Gaurdian:

An explosion in an eastern Kentucky coal mine killed five miners Saturday, Gov. Ernie Fletcher said. A sixth miner was able to walk away from the blast and out of the mine on his own.

The federal Mine Safety and Health Administration said that the five deaths Saturday raised the national death toll from coal mining accidents to 31 this year, with 10 of the deaths in Kentucky.
