Russia's only aircraft carrier, the Admiral Kuznetsov, caught fire on Thursday during maintenance work in Russia's Arctic port in Murmansk, with three people unaccounted for, one injured and six saved, Eurasia Diary reports citing Russian news agencies.
The fire had started on the upper deck and that thick, black smoke was billowing from the vessel.
"According to preliminary data, the fire hit the first power unit and a thick plume of black smoke is seen from the upper deck. Three were injured," the source said.
Firefighting effort is underway. The fire could have started due to violating safety rules during the repair works.
