A public inquiry in the U.K. has discovered that thousands of Britons and tourists were put at risk of radioactivity due to the poisoning of Russian spy Alexander Litvinenko in 2006. The spy, then 43, was poisoned with radioactive polonium-210 after meeting two Russian men at the Millennium Hotel in London’s Grosvenor Square. On his hospital bed, Litvinenko said he had “no doubt” Putin had given the order. Russia has always denied involvement in his death. According to the inquiry, there were two other attempts on his life.
