On the evening of Wednesday, November 11, Omsk Region came under attack by Ukrainian drones. Governor Vitaly Khotsenko said the region was under attack by unmanned aerial vehicles and that air defense forces were attempting to intercept the drones.
Residents of Omsk described explosions in different parts of the city that caused windows to shake. Eyewitness videos showed a glow and smoke over the industrial zone where the Omsk Oil Refinery is located. OSINT expert ASTRA said the glow was rising specifically near the refinery, while local residents wrote that a fire had broken out near the facility.

Airspace closed and communications restricted
NGS55 reported that the airspace over Omsk was closed after Khotsenko’s statement. Governor’s press secretary Mina Akhverdieva announced restrictions on cellular communications and mobile internet; air-raid sirens sounded in the city, while the local airport stopped accepting and dispatching flights, Ukrainska Pravda wrote, citing The Moscow Times.
The attack also affected the sporting calendar: the Russian Figure Skating Federation canceled the junior Grand Prix events scheduled for November 11 in Omsk “for safety reasons,” Kommersant reported. TASS said that the region’s emergency services continued operating at a heightened state of readiness that evening.
A short video published by ASTRA shows an orange glow over the industrial zone on the horizon from the outskirts of Omsk.
The country’s largest refinery
The Omsk Oil Refinery belongs to Gazprom Neft and is considered Russia’s largest oil refinery, with an annual capacity of about 22 million tonnes of crude oil. The facility is located approximately 2,500 km from the Ukrainian border. The Insider and ASTRA reported that the refinery had already been struck in July, after which it suspended operations, and in October 2026.
Ukrainian monitoring channels Exilenova+ and Supernova+ identified the refinery as the specific target of the attack. No information about casualties or the extent of damage at the facility had been published when this article was prepared. Reuters previously reported that drone strikes since late October had reduced the capacity of Russian refineries by approximately 30%.
