At least twenty people have died aboard a Russian nuclear submarine after a malfunction with the fire extinguishing system. A further 21 people were injured. A spokesman for the Russian fleet has said the sub’s nuclear reactor is not damaged and that radiation levels were normal.
Unconfirmed reports claim the vessel was an Akula-class submarine named the Nerpa. Its exact whereabouts at the time of the accident have not been revealed but it had been carrying out trials in the Japanese Sea. Some 208 people were said to be onboard.
The accident comes eight years after the sinking of the Kursk nuclear-powered submarine in which all 118 Russian crew members died.
