An accident aboard a nuclear-powered submarine in a training exercise has killed more than 20 people, Russian news agencies are reporting. State-run RIA-Novosti cites navy spokesman Capt. Igor Dygalo as saying a fire-extinguishing system went into operation in error Sunday aboard the submarine during tests in the Pacific Ocean. The reactor is working normally and radiation levels are normal, says Dygalo.
Dygalo is quoted as saying the dead include sailors and shipbuilders. He says 21 others were injured and evacuated to a ship that is escorting the submarine to shore. Russia's navy has been plagued by deadly accidents. In August 2000, the Kursk nuclear sub exploded and sank in the Barents Sea, killing its entire crew of 118.
