At least 52 dead in Russian mine collapse, officials say

A devastating explosion in a Siberian coal mine Thursday left 52 miners and rescuers dead about 820 feet underground, Russian officials said.

Hours after a methane gas explosion and fire filled the mine with toxic fumes, rescuers found 14 bodies but then were forced to halt the search for 38 others because of a buildup of methane and carbon monoxide gas from the fire. Another 239 people were rescued.

The state Tass and RIA-Novosti news agencies cited emergency officials as saying that there was no chance of finding any more survivors in the Listvyazhnaya mine, in the Kemerovo region of southwestern Siberia.
