The Dutch Safety Board will publish a final report on why Malaysian Airlines Flight MH17 broke up over Ukraine in 2014, killing all 298 on board.
The preliminary report said that the aircraft was hit by a high-energy object from outside, fuelling speculation that a surface-to-air missile was responsible.
The West and Ukraine alleged that Russian-backed rebels brought down the Boeing 777, while Russia blames Ukraine. But the report will not say who was to blame.
The plane – flying from Amsterdam to Kuala Lumpur – crashed in rebel-held eastern Ukraine on 17 July 2014 at the height of the conflict between government troops and the pro-Russian separatists.
There were 193 Dutch nationals among the victims.
