An explosion at a coal mine in southern West Virginia killed 25 miners and left four others missing on Monday.

The accident is the worst mine disaster in the country since a mine fire in Utah killed 27 people in 1984.

Mine deaths are relatively not common in the United States. Last year, the number of U.S. miners killed on the job was 34, 18 of them died in coal mines. Notable accidents in recent years include West Virginia's Sago Mine methane explosion, which killed 12 miners in 2006. Six also died in Utah's Crandall Canyon mine cave-in in 2007. Full Story >>
