There have been fresh claims that Russia was involved in the downing of Malaysian Airlines flight MH17 in Ukraine last year.

Pro-Russian separatists were accused of shooting down the plane killing all 298 people on board, including 80 children, with a Russian made missile.

It is a claim denied by the Kremlin.

Now Dutch prosecutors say parts suspected as being part of a Russian missile system have been found at the crash site.

Investigators say they have identified debris at the crash site that "possibly" come from the Russian-made missiles.

There are understood to be seven pieces of debris.

Russia has already vetoed a plan to set up a tribunal through the United Nations to prosecute whoever is suspected of downing the plane.

It is widely believed to have been hit by a surface-to-air missile, and Ukraine and the West have suggested that separatists backed by Russia or Russian troops themselves were responsible for shooting down the plane.

But Moscow has repeatedly dismissed the accusations and state media has suggested that Ukrainian jets were to blame.

Euan McDonald is editor at the Kyiv Post in Ukraine.

He told Newstalk Breakfast the Russia has changed its story, but is still adamant the missile was not theirs.
