Moscow ? A short-circuit sparked a fire aboard a Russian nuclear submarine in the Barents Sea, killing two seamen and injuring one other in the latest accident to plague the nation’s struggling navy, officials said Thursday.

There was no radiation leak and the vessel, the St. Daniil Moskovsky, also known as B-414, returned safely to its Arctic home base, officials said.

The blaze happened Wednesday night when a control panel in one of its sections caught fire, Russian navy chief Adm. Vladimir Masorin said in televised remarks.

The submarine’s two nuclear reactors were shut down by an automatic safety system when the fire erupted, and there was no radiation danger, navy officials said.
