Russian helicopter crash kills at least 19 MOSCOW (Reuters) - A helicopter packed with passengers crashed in Siberia on Tuesday, killing at least 19 of the 28 people aboard, Russia's civil aviation commission said. The Mi-8 aircraft operated by Polar Airlines caught fire after crashing in the Sakha region with 25 passengers and three crew on board, the Interstate Aviation Committee said. Citing a surviving crew member, the committee said on its website that 19 people were killed. State-run Itar-Tass later cited a regional government official as saying 23 people were killed and five survived, including a child. Sakha, also known as Yakutia, is a vast region stretching north of the Arctic circle and helicopters are frequently used to transport people to remote areas.
