Wreckage of flight MH17 is seen after the presentation of the investigation report on the cause of its crash, at the Gilze-Rijen air base, the Netherlands, on Oct. 13, 2015. The crash of flight MH17 on 17 July last year was caused by the detonation of a 9N314M-type warhead launched from eastern Ukraine using a Buk missile system, said the investigation report published Tuesday by the Dutch Safety Board (DSB).
