The investigation into the MH17 crash is conducted by Dutch prosecutors and the Dutch-led Joint Investigation Team (JIT). The international group of investigators claims that the plane was downed by a Buk missile belonging to the Russian armed forces, something Moscow categorically denies.
Russia conducted its own investigation and said it had provided the JIT with evidence, including radar data, showing that the plane had been shot down by a Ukrainian Buk missile. However, Moscow was denied any access to the probe.
