The submarine is lying on the ocean floor after it lost power in some kind of an accident. Bill Gasparini has the latest from Moscow. Russian Navy officials say that all 116 crewmembers on board the submarine are alive. However, they are not sure if any of the men are injured. Crewmembers have been tapping on the vessel's hull using coded signals.
Officials say they are hoping for a break in the weather.
Even with better weather, experts say any evacuation will be risky. The Kursk was involved in some kind of accident on Sunday, which forced the vessel down to the ocean floor. Russia's senior Navy commander said Monday the submarine was involved in a collision with an unknown object. But, later, officials said there may have been an explosion on the vessel. Officials say there are no nuclear weapons on board the Kursk, and that its two nuclear reactors have been shut down.
