A video distributed and authenticated by the AP appears to show a Ukrainian drone attack on a naval vessel, forcing the closure of Russia’s commodity export hub of Novorossiysk in the Black Sea for several hours. The overnight assault by two naval drones was repelled without damage to port facilities, according to the Russian Defense Ministry. Ukraine’s state security service was responsible for the attack that targeted and disabled the Russian landing ship Olenegorsky Gornyak, according to a security official familiar with the matter.
