On the evening of November 11, drones attacked the Russian city of Omsk. The presumed target was the Omsk oil refinery — the largest enterprise in the Russian oil refining industry. Local residents reported numerous explosions, and monitoring channels published footage of a suspected fire at the facility.
The attack was reported by the Ukrainian monitoring Telegram channel Exilenova+. Information about the drone raid on the Omsk region was confirmed by Russian regional authorities.
According to Exilenova+, the attack lasted for several hours. Explosions were heard repeatedly in the city, and air defense systems were active. The published videos show a bright glow and columns of smoke, presumably rising from the oil refining facility.
The monitoring channel claims that a large-scale fire broke out at the Omsk refinery as a result of the attack. However, the exact nature of the damage and possible consequences for production have not yet been established.
The Russian outlet The Insider also reported a likely attack on the oil refinery. Journalists reviewed eyewitness videos and determined that they capture a glow in the direction of the industrial zone where the facility is located. However, information about direct hits to equipment requires further confirmation.
Omsk region governor Vitaly Khotsenko confirmed the drone attack on the region and stated that Russian air defense systems were operating. However, he did not specify information about damage to the oil refinery or the scale of possible losses.
During the attack, a drone danger regime was introduced in Omsk. Local authorities temporarily restricted airport operations, causing flight delays. There were also reports of mobile communication restrictions and cancellation of some mass events.
The Omsk refinery is owned by Gazprom Neft and is the largest oil refining enterprise in Russia. Its design capacity exceeds 21 million tons of oil per year. The plant produces automotive gasoline, diesel fuel, aviation kerosene, oils and other petroleum products.
The facility is of great importance for the Russian fuel market. According to industry data, in 2024 it processed about 22 million tons of oil, producing approximately 5 million tons of gasoline and 8 million tons of diesel fuel.
This is not the first drone attack on the Omsk refinery in 2026. In July, after a strike, the enterprise was forced to suspend part of its production processes due to equipment damage. At that time, Reuters sources reported the shutdown of two major primary oil processing units.
In October, the plant was attacked again. The General Staff of the Ukrainian Armed Forces confirmed that the facility was hit, noting that such operations are aimed at reducing Russia's military-economic potential.
The new attack took place amid ongoing strikes on Russian oil refining infrastructure. According to Reuters on November 10, the latest series of attacks affected about 30% of Russia's oil refining capacity, although this does not mean that all affected facilities were shut down simultaneously.
At the time of the first reports of the attack on November 11, there was no official confirmation of damage to equipment at the Omsk refinery or a production halt. Information about the consequences of the strike is being updated.
