Malaysia Airlines flight MH17 was shot down by a missile fired from territory controlled by pro-Russian rebels in East Ukraine.
According to international prosecutors investigating the downing of flight MH17 over Eastern Ukraine in 2014, said the aircraft was hit by a Buk missile – a ground-based air defence system.
They said the missile launcher was brought into Ukraine from Russia.
The aircraft was hit during a flight between Amsterdam and Kuala Lumpur on July 17 2014, killing 280 passengers and 15 crew members.
"Based on the criminal investigation, we have concluded that flight MH17 was downed by a Buk missile of the series 9M83 that came from the territory of the Russian Federation," chief Dutch police investigator Wilbert Paulissen said.
The missile launcher was later taken back to Russia, he said.
Both Ukraine and Russia operate Buk systems, and the two countries have repeatedly accused one another of culpability for the crash
The investigation team interviews two hundred witnesses, and half a million videos and photographs were viewed.
The team was drawn from the Netherlands, Australia, Belgium, Malaysia and Ukraine.
