Ukrainian drones targeted Russia’s largest oil refinery in Omsk on November 11, striking the facility approximately 2,500 kilometers from the Ukrainian border.
The massive drone attack on the Siberian city lasted for several hours, according to The Kyiv Independent. Local officials and monitoring channels reported explosions and fires near the refinery, which is owned by Gazprom Neft.
The strike comes as a series of long-range drone campaigns has significantly impacted the Russian energy sector. The Atlantic Council reported that these attacks have reduced Russia’s oil refining capacity by around 30 percent.
Widespread infrastructure damage
Beyond the Omsk region, Ukrainian forces launched a broad assault against multiple targets. Earlier on November 11, drones struck the Ust-Luga port in Leningrad Oblast, an attack confirmed by Yahoo News. Ukraine’s General Staff said that Ukrainian drones struck the Novatek-Ust-Luga complex, damaging key components of an oil-processing unit and other technological equipment.
The scale of recent precision strikes has caused significant economic disruption. The New York Post reported that Ukraine’s Military Intelligence (HUR) agency estimated the strikes have knocked 15 of Russia’s 38 major oil refineries out of operation, causing more than $23.2 billion in damage.
The HUR agency estimated that only 12 refineries are currently running at reduced capacity. These precision strikes have reportedly wiped out nearly all of Moscow’s oil sector income from 2025. The agency said that five facilities hit as of September, including the Ryazan Oil Refining Company, accounted for 33% of Russia’s total volumes.
Omsk attack details
In Omsk, the drone threat alert was declared by Governor Vitaly Khotsenko at 12:40 p.m. Moscow time on November 11, remaining in effect until at least 8:10 p.m. Local reports from the monitoring channel Exilenova+ indicated that drones struck the Gazprom Neft refinery, causing a fire to spread through the industrial zone.
The independent Telegram channel Astra also confirmed a blaze near the site via OSINT analysis, though the exact extent of the damage and specific targets were not independently verified.
The Omsk refinery is the largest in Russia, with a processing capacity exceeding 21 million metric tons of crude annually. The facility is responsible for one out of every six liters of Russian gasoline and diesel fuel and provides supplies to the Russian military. This marks the fourth drone threat alert declared in Omsk since the beginning of October, and the second for the nearby city of Novosibirsk.
During the attack, air raid sirens sounded for over eight hours. Authorities in Omsk canceled several scheduled events for November 11, including theater and ballet performances, the Dostoevsky theater festival, and the Sila Sibiri “Power of Siberia” figure skating Grand Prix.
Governor Khotsenko also said that authorities restricted internet and mobile communication access, while residents reported blackouts in some districts. Khotsenko said that emergency crews were sent to locations affected by “falling drone debris,” but he did not specify which facilities were hit.
Refining outages trigger fuel shortages and rationing
The disruption to refining capacity has triggered fuel shortages across several Russian regions. The Atlantic Council said that these outages have prompted petrol rationing in some areas. Similar restrictions occurred during summer 2026, an earlier aerial offensive that was credited with causing the largest fuel crisis in Russia since the Soviet Union collapsed.
The cumulative effect of the strikes has altered Russia’s processing capabilities. According to the HUR, the strikes have cut Russia’s processing volumes by 55.4 percent compared to the beginning of the year.
Recent attacks since late October have disrupted operations at nine of Russia’s 35 largest refineries. These affected plants represent approximately 300,000 metric tons per day of nameplate capacity—roughly 2.2 million barrels per day—out of a total primary capacity of about 930,000 tons per day.
Russian Foreign Minister Sergei Lavrov said on Tuesday that a recent diesel supply arrangement was already helping to lower fuel prices, despite reports from Oilprice that domestic shortages have returned to several regions. This follows an October agreement announced by President Donald Trump for Russia to supply 300,000 metric tons of diesel to the United States and international markets.
In response to the shortages, Igor Ananskikh, a State Duma deputy from the “Fair Russia” party and member of the Energy Committee, attributed fuel sale restrictions to consumer panic buying rather than the strikes.

Ananskikh said that Rosneft has imposed restrictions in some regions to manage demand, comparing the situation to the summer when Russians bought buckwheat and sausage in bulk. He also acknowledged that massive airstrikes involving approximately 150 drones make damage to facilities inevitable.
Ukraine offers energy ceasefire if attacks stop
As the drone campaign continues, Ukraine has expressed willingness to negotiate regarding energy infrastructure. The Atlantic Council reported that Ukrainian officials remain open to an “energy ceasefire” if Russia stops attacking Ukraine’s civilian infrastructure.
President Volodymyr Zelensky expressed that Russia continues to hit critical energy infrastructure, including equipment that nuclear power plants depend on.
Russians are using Shahed drones and missiles to hit even the energy equipment that our nuclear power plants depend on.

The current escalation follows a period of tension regarding an “energy ceasefire” proposed by Donald Trump. While President Zelensky initially supported the proposal, he insisted any truce must be bilateral. Following the collapse of the ceasefire in October, Ukraine resumed strikes on October 30 after Russia continued bombing Ukraine’s civilian power grid.
While peace talks were scheduled for November 10–11 in Abu Dhabi, the two nations remain divided. U.S. envoy Jared Kushner spoke regarding potential progress in Moscow, stating:
I believe that hopefully tomorrow in Moscow, Steve (Witkoff) and I will be successful, and President Putin will give the blessing for that to occur.
