Malaysia Airlines Flight 17 (MH17/MAS17) was a scheduled international passenger flight from Amsterdam to Kuala Lumpur that crashed on 17 July 2014 after being shot down, killing all 283 passengers and 15 crew on board. The Boeing 777-200ER airliner lost contact about 50 km (31 mi) from the Ukraine–Russia border and crashed near Torez in Donetsk Oblast, Ukraine, 40 km (25 mi) from the border, over territory controlled by pro-Russian separatists. The crash occurred during the Battle in Shakhtarsk Raion, part of the ongoing war in Donbass, in an area controlled by the Donbass People’s Militia. According to American and German intelligence sources, the plane was shot down by pro-Russian separatists using a Buk surface-to-air missile fired from the territory which they controlled. The Russian government blamed the Ukrainian government. The Dutch Safety Board is currently leading an investigation into the incident and issued a preliminary report on 9 September 2014; a final accident report is expected in August 2015.
