25 dead in W. Virginia mine blast
A mine explosion in West Virginia killed 25 people in the country's worst mining disaster since 1984.
Rescue workers continue to search for four miners still missing from the blast.
Toxic gases forced rescue teams to halt operations as workers drilled holes to ventilate the area.
Kevin Stricklin, an administrator for the federal Mine Safety and Health Administration, says the situation for those missing was dire but rescuers would try to go back after the mine was ventilated.
Massey Energy Co.'s sprawling Upper Big Branch mine about 30 miles south of Charleston has a history of serious violations involving its plan for ventilating combustible methane gas.
