Vitaly Churkin
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.Churkin died in New York City on 20 February 2017, the eve of his 65th birthday. The immediate cause was heart failure, according to Russian diplomat Sergei Ordzhonikidze. The Russian Foreign Ministry noted that Churkin died while at work and expressed condolences to Churkin's family. India's Permanent Representative to the UN, Syed Akbaruddin, also expressed his condolences, calling Churkin a "friend" and a "stalwart diplomat". Former President Barack Obama's UN Ambassador, Samantha Power, tweeted that she was "devastated" and described Churkin as a "diplomatic maestro" who did all he could to bridge U.S.-Russia differences. Britain's ambassador to the UN, Matthew Rycroft, tweeted that he was "absolutely devastated", describing Churkin as "a diplomatic giant & wonderful character".
