Russia's defence ministry said in a briefing on Friday that Russian forces had destroyed two British-supplied Harpoon anti-ship missile systems in Ukraine's Odesa region overnight.
Reuters was unable to independently verify the claim.
The U.S.-designed missile systems are one of several weapons supplied to Ukraine by NATO countries since Russia sent its armed forces into the country on Feb. 24.
