"During the fire response, one of the soldiers of the Northern Fleet was killed. The search for an officer from the ship's vital service continues," the statement says.
Earlier in the day, regional emergency services said that 10 people were injured in the fire aboard the vessel, which is docked in the northern city of Murmansk for repairs. The head of the United Shipbuilding Corporation (USC), Alexei Rakhmanov, said that the fire broke out during welding works near the first energy compartment, as a spark fell into a hold space where fuel was spilt.
The officer of the ship's emergency service rushed immediately to the welding area to ensure the safe evacuation of the workers of the enterprise, it added.
