A Mi-8 helicopter crash landed in Russia's Urals on Tuesday, killing at least one person, emergencies services said.
The helicopter, which had four people on board, crash landed some 90 kilometers to the west of the city of Yekaterinburg at around 7:20 a.m. local time (03:20 GMT).
It is not immediately clear whether the other three people on board the crashed helicopter survived.
A helicopter carrying nine rescuers is expected to arrive at the site of the crash in a short time.
This is the third reported crash landing involving Mi-8 helicopters in just a week. On Sunday, a Mi-8 helicopter crash landed in the Western Siberian Krasnoyarsk region after its engine failed. There were four people and 2 tons of cargo on board the aircraft, which was not damaged.
Another Mi-8 helicopter crash landed on July 12 in the northern Komi Republic with no casualties.
The production of multipurpose Mi-8 helicopters started in 1965 in the city of Kazan. As of 2010, more than 10,000 Mi-8 helicopters have been produced, and more than 2,000 exported to some 40 countries.
