Ukraine's air force said on Tuesday that it had destroyed a major Russia landing ship stationed in the Crimean waters, after the Russian-installed governor of Crimea said that Kyiv's assault sparked a fire in the port of Feodosia. "And the fleet in Russia is getting smaller and smaller! Thanks to the Air Force pilots and everyone involved for the filigree work!" the commander of Ukraine's air force, Mykola Oleshchuk, said on the Telegram messaging app, without providing evidence.
