On Tuesday, Russian troops overran the last naval vessel still flying the Ukrainian flag on the Black Sea peninsula of Crimea, a regional Ukrainian defence official said. This happened a day after Russian forces took control of the Kostyantyn Olshanskiy, which, like the Cherkasy, had been blocked by Russian ships in western Crimea's Donuzlav Lake, defence ministry spokesman Vladyslav Seleznyov said in a statement published on his Facebook account.
