A local resident stands among the wreckage at the site of the crash of a Malaysia Airlines plane carrying 298 people from Amsterdam to Kuala Lumpur in Grabove, in rebel-held east Ukraine, on July 19, 2014. Ukraine and pro-Russian insurgents agreed on July 19 to set up a security zone around the crash site of a Malaysian jet whose downing in the rebel-held east has drawn global condemnation of the Kremlin. Outraged world leaders have demanded Russia's immediate cooperation in a prompt and independent probe into the shooting

GILZE-RIJEN, NETHERLANDS - OCTOBER 13:  A general view of the cockpit wreckage at the Gilze-Rijen Military Base on October 13, 2015 in Gilze-Rijen, Netherlands. The reports focus on four subjects: the cause of the crash, the issue of flying over conflict areas, the question why Dutch surviving relatives of the victims had to wait two to four days before receiving confirmation from the Dutch authorities that their loved ones were on board flight MH17, and lastly the question to what extent the occupants of flight MH17 were consciously of the crash.

Story highlights

Dutch-led group of prosecutors is gathering evidence for a potential criminal trial

Russia has denied any involvement in the incident

(CNN) —  

Malaysia Airlines Flight 17 was downed over eastern Ukraine by a Buk missile brought in from Russia and fired from a village under the control of pro-Russian separatists, a team of international prosecutors said Wednesday.

Speaking at a press conference in the Dutch city of Nieuwegein, Wilbert Paulissen, the head of the Dutch National Detective Force, said there was conclusive evidence that a missile from the Russian-made Buk 9M38 missile system downed the passenger flight on July 17, 2014, killing all 298 people on board.
