Ukraine's Oil Campaign Cuts Fuel Supply to Russian Black Sea Region

Ukrainian forces struck Russian oil facilities in Crimea and Krasnodar Krai on June 21, targeting refineries and export hubs that supply fuel to Russia's military operations and civilian markets. The cumulative campaign has forced Sevastopol to suspend fuel distribution and shut down major refineries. Ukraine aims to degrade Russian logistics capacity ahead of expected summer offensives in the east.
