No evidence given. This is a conspiracy theory about the coronavirus, and one of many recurring pro-Kremlin disinformation narratives aiming to undermine the results of the MH17 investigation and the outcomes of the future trial.
The Joint Investigation Team (JIT) - which is comprised of the Dutch Public Prosecution Service officials and the Dutch police, along with police and criminal justice authorities from Australia, Belgium, Malaysia and Ukraine - has concluded that flight MH17 was shot down on 17 July 2014 by a missile of the 9M38 series, launched by a BUK-TELAR, from farmland in the vicinity of Pervomaiskiy. At that time, the area was controlled by pro-Russian fighters. The BUK-TELAR was brought in from the territory of the Russian Federation and subsequently, after having shot down flight MH17, was taken back to the Russian Federation. The Dutch-led Joint Investigation Team (JIT) has concluded that the BUK-TELAR used to down MH17 originates from the 53rd Anti Aircraft Missile brigade, a unit of the Russian army from Kursk in the Russian Federation.
