Observers Cry Foul Over Kyiv's Release of Key Witness in Flight MH17 Probe Nataliya Leonova This story originated in [1]VOA's Ukrainian service. Some information is from AP. Some Western observers are criticizing a Ukrainian court's decision Thursday to release Volodymyr Tsemakh, a "person of interest" in the downing of Malaysia Airlines Flight 17 (MH17) five years ago. The decision, handed down by the Kyiv Court of Appeal, comes amid talks between Moscow and Kyiv on a prisoner swap that unconfirmed reports have said includes Tsemakh, a Ukrainian citizen who reportedly oversaw an anti-aircraft unit among Russia-backed rebels stationed near the commercial airliner's crash site in separatist-controlled eastern Ukraine. Shortly after reports of Tsemakh's release circulated, Russian President Vladimir Putin told reporters gathered at the Eastern Economic Forum in Vladivostok that he believes the swap is imminent and will be "rather large-scale, and a good step forward toward normalization [of relations with Ukraine]." In the swap, which is largely viewed as a pre-condition to quadrilateral "Normandy format" peace talks tentatively scheduled for later this month, Kyiv is seeking the return of 24 sailors detained by Russia last year off annexed Crimea, as well as filmmaker Oleg Sentsov and others, whom rights groups and the government in Kyiv say are "political prisoners" in Russia. Moscow is seeking the release of Kirill Vyshinsky, head of Russia's state-run news agency RIA Novosti's office in Ukraine, along with numerous separatist fighters and Russian service members whom, the Kremlin has long maintained, voluntarily fought alongside them.
