Ukraine says drones struck Omsk refinery nearly 2,500 km inside Russia

Ukrainian drones struck an oil refinery in Omsk, western Siberia, nearly 2,500 kilometers from Ukrainian territory, according to Ukraine’s military general staff. President Volodymyr Zelenskyy described the attack as a blow to Russia’s oil economy, while local Russian officials said emergency crews were deployed and reported no casualties.

The Omsk facility is close to Russia’s border with Kazakhstan and has an estimated capacity of more than 21 million metric tons of crude oil a year. It produces fuels, lubricants and petrochemical products, making it a significant asset in Russia’s downstream energy system.

Ukraine’s military general staff said Monday that the strike caused a fire at the plant. Omsk regional governor Vitaly Khotsenko confirmed on Telegram that the facility had been attacked by Ukraine and said emergency services were working at the site.

Zelenskyy said in his evening address that Ukraine’s “long-range sanctions” had reached the Omsk refinery, according to a translation of his remarks. He said upgraded Fire Point drones had extended the range of Ukrainian precision strikes into Siberia and called the operation an achievement for Ukraine’s armed forces.

Fire Point, based in Kyiv, is a Ukrainian defense technology company that develops drone and missile systems. Long-range drones allow Ukraine to target infrastructure far from the front line without using aircraft, an approach that can pressure Russia’s energy network while limiting direct exposure of Ukrainian pilots and crews.

Energy assets remain in focus

Ukraine has increased strikes on Russian oil infrastructure in recent months, seeking to reduce the resources available to President Vladimir Putin’s war effort, according to Ukrainian officials. Zelenskyy said Monday that Ukrainian forces had also hit oil facilities in Russia’s Yaroslavl region and other areas.

The Omsk refinery is the largest of Russia’s 11 gasoline producers to have been struck by Ukrainian forces, Ukraine’s military said. Refining capacity matters because plants such as Omsk turn crude oil into transport fuels and industrial products. Damage to processing units, storage or related infrastructure can affect operations even when crude production itself is not hit.

The attack came shortly before a NATO summit in Ankara, where leaders from 32 countries are expected to meet for two days beginning Tuesday. Ukraine’s long-range strike capabilities and Russia’s intensified air campaign are likely to form part of discussions among allies, though the summit agenda was not detailed in the statements cited.

Russia launched a separate wave of missiles and drones against Kyiv in the early hours of Monday, killing at least 19 people, authorities said. The attack followed another deadly strike on Ukraine’s capital last week.

Diplomacy around NATO summit

U.S. President Donald Trump held separate calls with Putin and Zelenskyy over the weekend. Trump said Monday that a resolution to the conflict was “getting closer than people realize.”

Trump is expected to meet Zelenskyy on the sidelines of the NATO summit in Ankara. The meeting would take place as Ukraine argues for continued Western support and as Russia continues long-range attacks on Ukrainian cities.

The war, now more than four years into Russia’s full-scale invasion of Ukraine, has increasingly included attacks beyond the battlefield. Kyiv’s latest claim places Siberian energy infrastructure within range of Ukrainian-made systems, while Moscow’s missile and drone barrages continue to impose heavy civilian costs in Ukraine’s capital.
