Race to rescue crew of Russian submarine

Russia was last nightracing against time to rescue seven sailors stranded in a mini-submarine on the Pacific Ocean floor with as little as 24 hours' air supply - an accident with echoes of the Kursk submarine disaster in which 118 seamen died.
Though on a far smaller scale, the accident came a week before the fifth anniversary of the sinking of the Kursk, a state-of-the-art nuclear submarine.
The Kursk crisis provided an early test for President Vladimir Putin, five months into his first term, when he was deemed to have handled the emergency poorly. The president waited a week before breaking off his holiday, then had a highly uncomfortable meeting with relatives of those lost on the submarine.
The Russian AS-28 mini-submarine, itself a rescue vessel, was taking part in a military exercise off Kamchatka in the Russian far east when its propeller snagged a fishing net. As it tried to pull free, naval officials said, the net became wrapped around the propeller and the submarine came to rest at a depth of 190m.
