Russian officials said Saturday there were no survivors in the crash of a helicopter with five people onboard in the mountains of Russia's Far East, according to UPI. The MI-8 helicopter went down Thursday in the Khabarovsk Territory for reasons that were still unknown. "The bodies of all five who died have been found," an official with the Emergencies Ministry told Russia's RIA Novosti news agency. The copter belonged to Russia's Voluntary Association of Assistance to the Army, Air Force and Navy. An investigation into the crash was begun and search crews at the scene were looking for the aircraft's flight recorder.
