During the Yugoslav Wars — in the Srebrenica massacre — about 7,500 people were killed by Bosnian Serb troops in a span of eleven days . It was later found to be an act of genocide by the International Court of Justice . The UK sponsored a resolution which would condemn the genocide and commemorate the 20th anniversary of the massacre . The Russian Federation , after Serbian President Tomislav Nikolić sent a letter to Russian President Vladimir Putin , was the only country on the security council that was against the resolution ( China and three other countries abstained ) : Churkin issued a veto on his country 's behalf at the UN Security Council on 8 July 2015
