A blaze has broken out during repair works on the Russian Navy's sole aircraft carrier, the Admiral Kuznetsov. Two servicemen have been injured, while two more people are reportedly missing.

The ship was undergoing repairs while docked at the Barents Sea port of Murmansk when fuel caught fire.

The blaze was sparked by welding in the first power section on the ship's deck, after which the fire spread to a space of 600 square meters (6,460 square feet), according to emergency services sources.

The Northern Fleet's press office later clarified that there was "a release of smoke into one of the compartments during welding works," and the source of the smoke was "localized." It added that there were no munitions on board.

All workers have been evacuated from the vessel. Two servicemen, who were helping to put out the fire, were treated for smoke inhalation, a spokesperson for Russia's Northern Fleet said.

Sources from the emergency services, meanwhile, told reporters that six people were injured. One shipyard worker is said to have sustained a head trauma.

Aleksey Rakhmanov, head of the state-run United Shipbuilding Corporation, told Interfax that "a human factor" could be the cause of the fire.

There were also reports that two people have gone missing but that so far this has not been officially confirmed.

Admiral Kuznetsov is Russia's only aircraft carrier. It has been undergoing repairs and maintenance since 2017, after completing a mission in the eastern Mediterranean, where the vessel took part in the country's campaign in Syria.
