Tourist helicopter crashes in Russian lake
A helicopter carrying tourists has plunged into a deep volcanic crater lake on the Kamchatka Peninsula in Russia's Far East, with rescue workers searching for up to eight people missing, officials have said.
At least eight others reportedly survived.
The Mi-8 helicopter crashed in the Kronotsky nature reserve, and the regional administration said rescuers were searching for survivors in Kurile Lake, which was formed in a volcano caldera and crater.
Russia's Emergencies Ministry said 13 tourists and three crew members were aboard the helicopter and eight people survived, according to the state RIA Novosti news agency.
Two of the survivors were badly injured and have been taken to the intensive care unit at a local hospital, the Interfax news agency reported.
Kronotsky reserve spokespeople said the lake was only 5C to 6C warm and the eight survivors had to swim about nine metres up to the surface from the crashed helicopter.
Russian news reports did not list the nationalities of the tourists aboard the helicopter, but said most of them were from Moscow and St. Petersburg.
Regional prosecutors were investigating a possible violation of flight safety rules.
The helicopter reportedly is lying at a depth of about 100 metres in the lake, which is up to 316m deep with an area of 77 square kilometres.
The helicopter, manufactured during the Soviet era 37 years ago, was operated by Vityaz-Aero, a local private carrier. Its director said it had recently undergone maintenance and was in good shape.
The Mi-8 is a two-engine helicopter designed in the 1960s. It has been used widely in Russia, ex-Soviet countries and many other nations.
The area where the crash occurred can only be reached by helicopter, and fog complicated rescue efforts, the RIA Novosti reported.
A total of 15 rescuers, including six divers, were involved in the rescue operation, according to Interfax.
Kamchatka, the pristine peninsula which is home to numerous volcanoes, is known for its rugged beauty and rich wildlife.
The Kronotsky reserve, which has Russia's only geyser basin, is a major tourist attraction on Kamchatka and helicopters regularly carry tourists there.
Quickly changing weather often makes flights risky. Last month, an An-26 passenger plane crashed on Kamchatka while approaching an airport in bad weather, killing all 28 people on board.
