Dutch investigators want Russia to hand over radar data that Russia says proves a Ukrainian jet was in the vicinity of flight MH17 when it was downed.

Speaking to Der Spiegel magazine on Monday, Dutch chief investigator Fred Westerbeke said his team was preparing a request for assistance.

Russia maintains a Ukrainian fighter jet shot down flight MH17 on 17 July.

But Ukraine and the West blame pro-Russian separatists armed with a Russian BUK surface-to-air missile.

Mr Westerbeke told the magazine (in German) that investigators had ruled out the possibility of an accident or a terrorist attack.

He said Malaysia Airlines flight MH17 may have been shot down by a surface-to-air missile or another aircraft, though the former suggestion is more likely.

A July report by Dutch investigators found that the Boeing-777 "broke up in the air probably as the result of structural damage caused by a large number of high-velocity objects that penetrated the aircraft from outside".

The report added that there was "no evidence of technical or human error".

Iron pieces

The investigators are also waiting for satellite images from the US that might give more details about the flight's crash.

Mr Westerbeke urged patience with the investigation, saying it will take the entirety of next year and possibly longer.

Investigators have been carrying out forensic tests on iron pieces found in the plane's wreckage that might prove it was hit by a surface-to-air missile.

Flight MH17 was flying from Amsterdam to Kuala Lumpur when it crashed in rebel-held territory in eastern Ukraine.

All 298 people aboard, mostly Dutch citizens, were killed.

Consequently the Netherlands announced it would take the lead in investigating the causes of the incident.
