Three people were killed and another one was injured in a helicopter crash on April 16 in the Perm Territory in Russia's Urals, Gazpromavia air company said.

"We confirm that three people -- two crewmembers and a passenger -- have been killed and the survivor, the other passenger, was taken to hospital," a spokesman for Gazpromavia said.

The Mi-2 helicopter with four people aboard lost contact with air traffic control earlier on April 16. Its wreckage was later found some 16 kilometers south of the village of Kalino, near Perm.

A spokesman for the Russian Emergency Situations Ministry said the helicopter crashed after colliding with electric power lines.
