An armed pro-Russian separatist takes pictures at the site of a Malaysia Airlines Boeing 777 plane crash, MH17, near the settlement of Grabovo in the Donetsk region on 17 July 2014. According to the JIT, "the BUK-TELAR that was used to down MH17, originates from the 53rd Anti-Aircraft Missile brigade (hereinafter 53rd brigade), a unit of the Russian army from Kursk in the Russian Federation".
It was subsequently shipped to a military unit numbered 20152 in what is now Ukraine in December 29, 1986.
The Russian authorities have proposed several theories for the tragedy to explain the causes of the crash, among which the involvement of a fighter aircraft in Ukrainian.
Lt. Gen. Nikolia Parshin, the ministry of defence's chief of the Missile and Artillery Directorate, told reporters that they were able to track down the Buk missile's paper trail using two serial numbers found on fragments of the rocket.
Russian General Nikolay Parshin said the number 8868720 was traced to a missile manufactured at a military plant in Dolgoprudny, near Moscow.
A part of the BUK-TELAR rocket that was sacked on the MH17 flight is displayed on a table during the conference of the Joint Investigation Team (JIT), in Bunnik on May 24, 2018.
In May, prosecutors investigating the downing of MH17 over eastern Ukraine in 2014 said they had identified the missile used to shoot down the plane as coming from Russia's armed forces.
Asked about the possibility that the separatists may have seized the missile system during fighting in 2014, Defense Ministry spokesman Maj.
The missile with this serial number was given number 886847379 in the military.
On the day that MH17 came down, a rebel commander posted that his troops had shot down a Ukrainian military plane.
A highly placed rebel, speaking to the AP shortly after the crash, admitted that rebels were responsible.
The Russian Foreign Ministry has said it expects relations between Moscow and Kiev to normalize sooner or later, but added that close ties would most likely be restored following a change of government in Ukraine.
Oleksandr Turchynov, secretary of Ukraine's Security and Defence Council, said on Monday that Russia's claim is "yet another failed fake report that the Kremlin made up in order to cover up their crime that has been proven by the official investigation as well as independent experts".
It cited factors such as the way light fell on the moving vehicle and claimed it is shown driving in reverse.
