Dutch authorities are expected to publish a preliminary report into the shooting down of Malaysia Airlines flight MH17 later.
The Netherlands is co-ordinating criminal investigations into the July 17 disaster by multiple countries, including Ukraine, Malaysia, Australia and Belgium.
The report will set out what is believed to have happened, but will not apportion blame.
All 298 passengers and crew on board the plane were killed when the aircraft, which was flying from Amsterdam to Kuala Lumpur over an area in eastern Ukraine controlled by pro-Russian separatists.
The rebels in Ukraine have publicly denied responsibility for shooting down the aircraft.
Only 193 of those on board have been positively identified, including Newcastle United fans Liam Sweeney, 28, and John Alder, 63, who were travelling to New Zealand to watch their team play.
Forensic teams are still trying to identify remains found in the wreckage of the aircraft.
Most of those on board were Dutch, but there were also people from Canada, Germany, Indonesia, New Zealand, the Philippines and the UK.
Rebels in Ukraine prevented medical personnel from recovering the bodies of victims as fighting erupted with Ukrainian forces.
The crash occurred just months after the still-unexplained disappearance of Malaysia Airlines flight MH370.
