Russian attacks have destroyed an oil refinery in the central Poltava region and struck "critical infrastructure", most likely oil facilities, near the port city of Odesa, local officials said on Sunday.
Russian forces have attacked Odesa, the main base for Ukraine's navy, alongside other Ukrainian Black Sea ports such as Mariupol and Mykolaiv. If taken, it would give Russia a land corridor from Crimea to Transniestria, a Russian-speaking breakaway province of Moldova that hosts Russian troops.
