International investigators say there are strong indications that Russian President Vladimir Putin decided to supply the missile that brought down Malaysia Airlines flight MH17 in 2014.
The missile struck the aircraft above Ukraine, killing 298 people.
While the evidence points to Putin supplying the weapon, there is no suggestion he directly ordered the aircraft be shot down.
The passenger aircraft was hit by a Russian-made missile over Ukraine, killing nearly 300 people.
The investigation team sighted recorded phone conversations which indicated the decision to supply weapons “rests with the President.”
“There is concrete information that the separatists’ request was presented to the president, and that this request was granted,” the report said.
And, while the “high bar of complete and conclusive evidence” is not reached,” Putin would be immune from prosecution as head of state.
Last year, a Dutch court found two Russians and a Ukrainian guilty of murder in absentia.
A ruling which Putin’s administration described as “scandalous” and politically motivated.
While the investigation had come to the conclusion Putin had made the decision to supply the missile, there was no sufficient evidence to continue the investigation or any criminal proceedings.
The Boeing 777 was hit while flying over the Donbas region of Ukraine while enroute from Amsterdam to Kuala Lumpur.
There were 27 Australians and one New Zealander among those killed in the incident.
The European Court of Human Rights has also launched an investigation into the downing of MH 17.
