Russia-Ukraine war: List of key events, day 723

Ukraine said it critically damaged the Caesar Kunikov, a Russian landing warship, off occupied Crimea, in a drone attack, the latest blow to the Russian navy's Black Sea Fleet. Ukraine said the ship, one of Russia's newest vessels, had a crew of 87 and had taken part in wars in Georgia and Syria as well as Ukraine. There was no official comment from Russia on the attack. Newly-appointed Ukrainian armed forces chief Oleksandr Syrskyii visited troops fighting around the key flashpoint of Avdiivka on the eastern front line, and described the situation as "extremely complex and stressful". Syrskyii, who was accompanied by Defence Minister Rustem Umerov, said Russian forces had "a numerical advantage in personnel".
