Ukraine strikes Russia's largest refinery at Omsk again

Ukraine's Special Operations Forces said its Deep Strike units attacked Gazprom Neft's Omsk refinery, Russia's largest, on Wednesday for the third time this year, and Omsk's governor confirmed a drone attack on the region during an alert that lasted more than eight hours.

Why it matters: Omsk processes about 22 million tonnes of crude a year, roughly 440,000 barrels a day, some 2,500 kilometres from Ukraine's border, and a third hit on the plant extends a refinery campaign that has already taken a large share of Russian processing capacity offline at points this year.

Data as of Bloomberg report of November 12, 2026, opening paragraphs read via the estate browser route (the rest is paywalled), corroborated by The Kyiv Independent's report of November 11, 2026 on the eight hour attack, the fire reported near the refinery and Governor Vitaly Khotsenko's confirmation of an attack on the region. The strike claim is Ukraine's and the extent of damage at the plant is not yet confirmed, so the item ships at grade C. Developing item.

Ukraine said it attacked Russia’s largest oil refinery for a third time on Wednesday. The Special Operations Forces said its Deep Strike units hit the Omsk plant in western Siberia, giving no details of damage, Bloomberg reported, and the city spent more than eight hours under a drone alert on November 11, with residents reporting a fire near the refinery and the independent Russian channel Astra’s analysis confirming a blaze near the site, The Kyiv Independent reported.

Omsk governor Vitaly Khotsenko confirmed Ukrainian drones were attacking the region and said emergency workers were sent to sites hit by falling drone debris, without naming the facilities struck. The Gazprom Neft refinery, which processes over 21 million tonnes of crude a year, was previously hit in July and October 2026, and the precise extent of damage from this strike is not yet clear.
