Analysis of information sources in references of the Wikipedia article "Murder of Pentecostals in Sloviansk" in English language version.
That pro-Russia separatists kidnapped and murdered four members of a Pentecostal church in Slaviansk seems sure. But very little else about the incident is [...] In mid-July, for example, state-run Voice of Russia reported that the "mutilated bodies" of two priests had been found in the Slaviansk grave. It purported to quote Anton Gerashchenko, an adviser to Ukraine's Minister of Internal Affairs, saying the churchmen "were tortured and killed by the Ukrainian nationalists." He was misquoted, however, and told the Monitor in Kyiv that the "terrorist" killers were in fact pro-Russian separatists, not Ukrainians.
