Ukrainian drone strikes set a major oil refinery ablaze in Russia’s Krasnodar region over the weekend, part of a sustained campaign to undermine Moscow’s war revenue and fuel supply. The attack, which killed at least one person, hit a facility that processes millions of tons of crude annually and supplies Black Sea exports. Fuel shortages have followed, with Crimea suspending gasoline sales to civilians and Siberian gas stations rationing purchases. Speaking at a ruling party conference, Russian President Vladimir Putin acknowledged the country faces a challenging period but insisted the government would meet all its commitments to citizens, without explicitly mentioning the strikes. He said domestic development programs, including housing and infrastructure, would continue as planned. The assault reflects Ukraine’s strategy to pressure the Kremlin toward negotiations by disrupting Russian energy and logistics.
