Malaysia Airlines Flight 17 (MH17/MAS17)[a] was a scheduled international passenger flight from Amsterdam to Kuala Lumpur that crashed on 17 July 2014, presumed to have been shot down, killing all 283 passengers and 15 crew on board.[2] 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,[3] over territory controlled by pro-Russian separatists.[4] 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 US intelligence sources, intelligence assembled in the five days after the crash pointed overwhelmingly to pro-Russian separatists having shot down the plane using a Buk surface-to-air missile fired from the territory which they controlled. The Russian government however blamed the Ukrainian Government.[5] and the Russian defence minister has said that Ukraine "bears full, total responsibility" for the crash because it happened in Ukrainian airspace.[6] The Dutch Safety Board is now leading an investigation into the incident and issued a preliminary report on 9 September while a final accident report is expected within one year.[2]
