Two Ukrainian warships have been shot down above the Kerch Bridge, which connects the Russian mainland with the annexed Crimean peninsula, the Russian-appointed governor of the peninsula said.
Governor Sergej Aksyonov writes on social media that the bridge was not damaged in the attempted attack.
Russia claimed earlier on Saturday that it had shot down 20 Ukrainian drones near the Crimean peninsula.
Ukraine has neither commented on the information about the 20 drones nor the two rockets.
