The Russian military says the missile that shot down Malaysia Airlines Flight 17, killing all 298 people on board, came from the arsenals of the Ukrainian army, not from Russia.
The jet was shot down by a Soviet-made missile over rebel-held eastern Ukraine in July 2014, about 40 kilometres from the Russian border, where fighting had been raging for months between Ukrainian forces and Russian-backed separatists.
There were 27 Australians on board.
The Netherlands and Australia announced in May that they believe the missile was transported to Ukraine from a military unit in the Russian city of Kursk.
Russia has vehemently denied involvement and has over the years come up with various theories as to the cause of the crash, generally laying the blame on the Ukrainian side.
Lt Gen Nikolai Parshin, chief of the Missile and Artillery Directorate at the Russian defence ministry, told reporters on Monday that the military had studied and declassified archives at the research centre outside Moscow that produced the Buk missiles after the Dutch investigators displayed parts of the missile and their serial numbers.
Parshin said the Russian archives show that the missile that was made of these parts was transported to a military unit in western Ukraine in 1986 and to Russia’s knowledge, never left Ukraine.
Asked about the possibility that the separatists may have seized the missile system during fighting in 2014,ministry spokesman Maj Gen Igor Konashenkov conceded that Russia does not have any documents proving otherwise but pointed to the statements of Ukrainian officials who have denied that separatists seized any of their Buks.
The Joint Investigation Team, set up by nations that lost citizens in the MH17 crash, said in a statement that it has “taken note” of the information that the Russian military made public on Monday.
The investigators said they had asked Russia for information regarding the serial numbers before but had not received a reply.
The separatists in the weeks prior to the plane crash bragged on social media about shooting down Ukrainian military aircraft.
On the day that MH17 crashed, a rebel commander posted that his troops had shot down a Ukrainian military plane. He later said his account has been hacked and that the rebels did not shoot down any aircraft that day.
A highly placed rebel, speaking to the AP shortly after the crash, admitted that rebels were responsible.
The rebels believed they were targeting a Ukrainian military plane, the person said.
He did not speculate, however, on a possible role of the Russian military in the attack.
The Russian military did provide material assistance to the rebels, and journalists sighted sophisticated weapons in the separatist-controlled areas that were never in Ukraine’s arsenals.
