Ukrainian man, who attended Russia-Ukraine peace talks, found dead amid claims of spying

Denis Kireev, a member of Ukraine's negotiating team during first round of peace talks with Russia, was found dead amid claims he was a spy. Ukraine's Ministry of Defence said the 45-year-old was killed during an operation to "defend the nation" but some Ukrainian MPs claimed he was killed by Ukraine's security service after resisting arrest on suspicion of treason.
