The Russian government tried to effectively block or prevent any kind of international prosecution of its role in suspected war crimes by an international court, using even its seat at the Security Council to veto resolutions which called for an investigation and bringing accountability of the downing the Malaysia Airlines Flight 17 over Donetsk Oblast and for crimes being committed in Syria. It even denied that a chemical attack had taken place in Douma on 7 April 2018, but this was nonetheless confirmed in a report by the UN-backed Organisation for the Prohibition of Chemical Weapons.
