Eighteen people have died in a Russian helicopter crash in north-western Siberia, officials say.

The oil field is operated by Russian national oil company Rosneft through its subsidiary Vankorneft.

A UTair ATR 72 crashed in Siberia in 2012, killing 33 of the 43 people aboard, after failing to be de-iced before takeoff.

The two aircraft were owned by UTair-Helicopter Services, a unit of Russian airline UTair.

The crew of the cargo-carrying helicopter were not injured and there was no adverse weather conditions, said Rosaviatsia.

The helicopter was manufactured in 2010.

The country's Investigative Committee said it opened a criminal investigation into the crash.
