The mayor of Novorossiisk, a crucial Russian Black Sea port city, issued a sea drone alert on Thursday morning, urging residents to avoid the shoreline due to potential threats from Ukrainian drones. Ukrainian sea drones have previously disrupted Russian ships near the port, impacting traffic. Novorossiisk serves as Russia's largest Black Sea port, vital for exporting crude oil, oil products, and various commodities. The Russian defense ministry reported destroying 10 Ukrainian sea drones approaching Crimea and 33 air drones over the peninsula overnight, intensifying tensions in the region.
