Malaysian Airlines has confirmed that one of its Boeing 777s has crashed in eastern Ukraine, about 31 miles from the border with Russia. Flight MH17 was en route from Amsterdam to Kuala Lumpur with 280 passengers and 15 crew on board. According to Ukrainian air traffic controllers, they lost contact with the aircraft at around 14.15 UTC almost 20 miles from the waypoint at Tamak. The Ukrainian government has refuted accusations by militia opposed to the Ukrainian government that the country's military shot down the airliner, which was cruising at 33,000 feet. Military experts have said that it would have required a long-range surface-to-air missile or air-to-air weapons to shoot down an aircraft at that altitude. Boeing issued a statement expressing concern over the incident and saying that it is ready to assist authorities as required. Virgin Atlantic Airways, Air France-KLM, Lufthansa, Delta and Russian carrier Transaero issued statements saying that they will re-route flights to avoid over-flying Ukraine. UK transport officials said that several flights flying towards the region have been re-routed.
