Tired but happy, seven relieved Russian sailors trapped in a mini-submarine finally emerged from the vessel after enduring a three day ordeal unsure if they would live or die. The sub had got its propeller caught up in deep-sea cabling on Thursday and was stuck some 200 metres beneath the ocean surface off Russia’s far eastern coast. As the drama unfolded concern mounted over the men’s oxygen supply. Attempts to drag the vessel to safety failed and hopes were pinned on US and British rescue vehicles which rushed to the scene.Finally this morning a British unmanned underwater vehicle cut the sub free. President Vladimir Putin has come under fire for reacting too slowly to the accident. His Defence Minister arrived to take charge of the operation this morning, Sergei Ivanov came just in time to see the sub surface. The waters where the vessel got stuck are said to have strategic installations and there have been suggestions Russia was not keen on allowing foreign forces into the area.
