Russian authorities say an aircraft with six people on board has disappeared from radar in the Far Eastern region of Khabarovsk.
Communication was lost with the Antonov An-26 aircraft while it was flying “38 kilometers from the Khabarovsk city airport, presumably in the area of Khekhtsir Nature Reserve."
The Russian Emergencies Ministry said the plane was carrying a crew of six people, according to preliminary data, adding that the aircraft was performing a technical flight.
"Searches are complicated by the dark time of the day and unfavorable weather conditions," the ministry said.
A group of rescuers and an Mi-8 helicopter have been dispatched to the area.
The An-26 is a civilian and military transport plane equipped with two turboprop engines designed and produced in the Soviet Union from 1969 to 1986.
