A Russian passenger plane has gone missing outside the Siberian city of Tomsk, according to the Interfax news agency.

It was not immediately clear how many people were on board the aircraft but estimates range from 13-17 passengers.

It comes just days after a plane carrying 28 people crashed in the far east of the country.

The Antonov An-26 twin-engined turboprop missed a scheduled communication and disappeared from radar during its flight from the city of Petropavlovsk-Kamchatskiy.

The wreckage was later found on a coastal cliffside and in the sea.

Russian media reported that none of the six crew members or 22 passengers on board had survived.

The weather in the area was cloudy at the time the plane went missing, Russian news agencies reported.

The aircraft involved had reportedly been in service since 1982.

Russian aviation safety standards have improved in recent years but accidents, especially involving ageing planes in far-flung regions, are not uncommon.

The Soviet-era plane type, still used for military and civilian flights in some countries, has been involved in dozens of deadly crashes since it entered service around 50 years ago.

An Antonov-28, a similar plane, slammed into a Kamchatka forest in 2012 in a crash that killed 10 people along the same route.

Investigators said both pilots were drunk at the time of the crash.
