Survivors recall panic on deadly Russian submarine

Survivors recalled the terrifying seconds after toxic gas was accidentally pumped into their nuclear submarine in an accident in which 20 people were killed, Russian media reported Tuesday.  The submarine was overcrowded, locked cabin doors had to be smashed down and some of the sleeping crew were too dazed to put on gas masks, they said, after the biggest Russian naval disaster since the sinking of the Kursk in 2000.
