A fire broke out on the flagship of the Russian Navy, according to local media reports. The blaze started on the Admiral Kuznetsov, Russia's only aircraft carrier, while it was docked at the Zvyozdochka shipyard in the Barents Sea port city of Murmansk, located in the far north-west of Russia, news agency Tass said. An emergency services source told the agency on Thursday morning that 20 people had been evacuated, the fire was extinguished and that "there were no casualties."
