A Russian Ka-27 helicopter was destroyed in Ukraine's Moscow-occupied Crimea region, Ukrainian Navy spokesman Dmytro Pletenchuk wrote on Facebook on April 10. "Minus [one] Russian Ka-27 in Crimea. Been looking for something. Found it," Pletenchuk wrote without giving further details. "I am not yet ready to provide verified information on this matter," Pletenchuk later told RFE/RL. Russia did not comment on the Ukrainian claim, which could not be independently verified. The Ka-27 is an anti-submarine helicopter developed during Soviet times. In February, the Ukrainian military reported the destruction of a Russian K-52 attack helicopter in the Avdiyivka area of Donetsk. To read the original story by RFE/RL's Ukrainian Service, click here.
