Separately, Robert Brovdi (“Madyar”), commander of Ukraine’s Unmanned Systems Forces, said drone units struck 13 vessels near Russian-occupied Crimea overnight. According to Brovdi, the targets included 10 tankers, one cargo ship, one ferry and one tugboat, adding that all of the tankers had been identified as part of Russia’s sanctioned shadow fleet. The General Staff also reported strikes on several fuel infrastructure facilities inside Russia, including the Ilsky oil refinery in Russia’s Krasnodar region, where explosions triggered a fire. The refinery is one of southern Russia’s largest oil-processing facilities, with an annual processing capacity of up to 6.6 million metric tons. Ukrainian officials said it produces gasoline, diesel fuel and other petroleum products used to support Russia’s military logistics.
