Five people were dead after a Flixbus veered to the right of the busy A9 motorway, local media reports
The plane had been carrying a group of parachute jumpers onboard, the Emergencies Ministry said, according to the TASS news agency. Seven people were pulled alive from the wreckage, it said.
The plane was a Let L-410 Turbolet, which is a twin-engine short-range transport aircraft.
Russian aviation safety standards have improved in recent years but accidents, especially involving ageing planes in far-flung regions, are not uncommon.
An ageing Antonov An-26 transport plane crashed in the Russian far east last month killing six people. All 28 people on board an Antonov An-26 twin-engine turboprop died in a crash in Kamchatka in July.
