Rescuers in the Russian far-east have found no survivors in the wreckage of a helicopter that disappeared while carrying 22 people “ most of them tourists.

Such accidents are relatively frequent in Russias far-east, which is sparsely populated and suffers harsh weather. Three years ago eight people were killed when a tourist helicopter crashed into a lake in Kamchatka.

The Mi-8T helicopter that disappeared from radar on Saturday was carrying 19 tourists and three crew.

The wreckage was found on Sunday morning in a hilly area, Kamchatka Governor Vladimir Solodov said on Telegram.

Footage posted to the messaging app by Russias emergencies ministry showed helicopter debris lying near a slope close to a large wooded hill. Officials said the wreckage was found near the location where the helicopter went off radar.

An emergency ministry official, Ivan Lemikhov, said17 bodies had been found so far and searches for those still missing had been paused, slated to resume at daybreak on Monday.

Russias Interfax news agency reported that pilot error, possibly caused by fog, was the main theory regarding the cause of the crash.

The aircraft was owned by Vityaz-Aero, a Kamchatka-based company that organises flights for tourists.

Designed during the Soviet-era, the Mi-8 helicopter is still widely used in Russia. (BBC)
