Ukraine Strikes Russia’s Largest Oil Refinery in Western Siberia

July 6, 2026 Black smoke rising above the Gazprom Neft Omsk Refinery on July 6, 2026. Social media The Ukrainian military said Monday that its drones struck Russia’s largest oil refinery in the western Siberian region of Omsk, marking one of the deepest attacks on Russian territory since the full-scale invasion of Ukraine. The Gazprom Neft-operated refinery is located on the northern outskirts of the city of Omsk, around 2,500 kilometers (1,550 miles) from the border with Ukraine. NASA satellites recorded multiple fire hotspots at the facility on Monday evening. “An impact with subsequent fire was recorded on the territory [of the refinery]. The extent of the damage is being verified,” Ukraine’s General Staff said in a statement on Facebook. “This is the last of the 11 largest gasoline producers in Russia that have been hit.” Omsk region Governor Vitaly Khotsenko confirmed that “several drones” had broken through layers of Russian air defense to reach the city’s “northern industrial hub.” Without specifying what, if anything, was hit, Khotsenko said that emergency services were dispatched to the area. The strikes mark the first time the Omsk region has come under a Ukrainian drone attack since the 2022 invasion. Sources told Reuters that the Omsk refinery processed around 23 million metric tons, or 460,000 barrels, of oil daily last year. Meanwhile, Ukraine’s HUR military intelligence agency said Monday that it carried out a deep-strike operation that hit one of Russia’s five largest refineries, the Slavneft-Yanos refinery in the Yaroslavl region, some 700 kilometers (435 miles) from the border with Ukraine. Ukraine’s General Staff said in a separate statement that it documented “explosions and smoke” at the refinery. In northwestern Russia’s Leningrad region, Ukraine said it struck the Novatek natural gas producer’s Ust-Luga complex on the Baltic Sea and the deployment point of a Russian missile brigade. Ukrainian forces said they also carried out multiple attacks in Russian-controlled parts of Ukraine, including one of annexed Crimea’s largest petroleum storage and shipment facilities in the port city of Kerch, as well as a key transport corridor and a drone warehouse in the occupied Luhansk region.
