The aircraft – which had 43 passengers, including five children, and six crew on board – was flying from the city of Blagoveshchensk on the Russian-Chinese border to the town of Tynda, regional governor Vasily Orlov said.
“All necessary forces and means have been deployed to search for the plane,” Mr Orlov said on Telegram.

Burning fuselage was found by a rescue helicopter, emergency officials said.
The An-24 passenger jet, operated by a Siberia-based airline called Angara, disappeared from radar over the area, local officials said earlier.
