Ukrainian drones strike Russia's largest oil refinery in Omsk, fire breaks out
On 8 October, Ukrainian drones attacked the Omsk oil refinery, Russia's largest, located roughly 2,500 km from the Ukrainian border. A fire broke out at the Gazprom Neft facility, which produces about one sixth of Russia's gasoline and diesel. Ukraine's General Staff confirmed the strike, and the same day its forces also hit a refinery in Bashkortostan.
Key points
- Omsk Oblast governor Vitaliy Khotsenko reported a Ukrainian drone attack on the region on 8 October, with air defence forces repelling the strike.
- A fire broke out at the Omsk oil refinery after the drone hit, according to Khotsenko and video published by the OSINT channel Exilenova+.
- The Omsk refinery is Russia's largest oil refinery and is owned by Gazprom Neft, a Gazprom subsidiary; it has an annual processing capacity of about 22 million tonnes of oil.
- The refinery produces roughly every sixth litre of Russian gasoline and Euro-5 diesel and is involved in supplying the Russian army.
- The General Staff of Ukraine's Armed Forces confirmed that Ukrainian Defence Forces struck the Omsk refinery, and domestic drone maker Fire Point said its modernised FP-1 drones were used.
- It was the second drone strike on the Omsk refinery in three months; the first hit on 6 July 2026, attributed to the SSO's Deep Strike unit, damaged primary processing units and forced a halt to operations.
- On the same day, Ukrainian forces also struck the Gazprom Neftekhim Salavat petrochemical complex in Bashkortostan.
Why it matters
The Omsk refinery is Russia's largest, producing around one sixth of the country's gasoline and Euro-5 diesel and supplying the Russian military, so a successful strike on it affects both civilian fuel markets and military logistics. The attack demonstrates that Ukrainian drones can now reach targets more than 2,500 km inside Russia, well beyond previously known strike ranges. Coming on the same day as a strike on the Salavat refinery in Bashkortostan, it signals a coordinated campaign of long-range, multi-target operations against Russian oil infrastructure deep inside the country.
What happened
On 8 October, Ukrainian drones struck the Omsk oil refinery, owned by Gazprom Neft and located roughly 2,500 km from the Ukrainian border. Omsk Oblast governor Vitaliy Khotsenko reported the attack and said air defence forces were continuing to repel it, describing the situation as under control. A fire broke out at the refinery after the strike, with footage circulated by the OSINT channel Exilenova+ showing the blaze and Russian air defence attempts to intercept the drones. Ukraine's General Staff confirmed that its Defence Forces had hit the refinery, and domestic drone maker Fire Point said the strike was carried out using its modernised FP-1 drones. Before the attack, local authorities had restricted mobile internet in the region and closed Omsk airport, and residents reported hearing explosions near the refinery and queuing at petrol stations after air-raid sirens. The Omsk refinery had previously been hit on 6 July 2026, in a strike attributed to the Special Operations Forces' Deep Strike unit, which damaged primary processing units and forced the plant to halt operations. On the same day as the October strike, Ukrainian forces also struck the Gazprom Neftekhim Salavat petrochemical complex in Salavat, Republic of Bashkortostan.
How Ukrainian sources describe it
Ukrainian sources uniformly frame the strike as a deliberate long-range operation by Ukraine's Defence Forces, highlighting the involvement of the General Staff, the Special Operations Forces' Deep Strike unit, and the domestic drone maker Fire Point. They emphasise the strategic significance of hitting Russia's largest refinery, its ownership by Gazprom Neft, its location more than 2,500 km from Ukraine, and its role in supplying the Russian army, portraying the attack as a demonstration of Ukrainian drone capabilities and a blow to Russian fuel and military logistics. Ukrainian reporting also foregrounds the second-strike nature of the event — following the July attack — and the same-day strike on the Salavat refinery, presenting a pattern of escalating, multi-target strikes deep inside Russia.
Where reporting differs
Sources give slightly different figures for the Omsk refinery's annual processing capacity: some state up to 22 million tonnes, others over 21 million tonnes, and one specifies 22.23 million tonnes. There is also disagreement on the distance covered by the drones: most sources describe the refinery as roughly 2,500 km from the Ukrainian border, while the General Staff of Ukraine's Armed Forces and Fire Point say the drones covered up to 3,000 km to reach the target.
Background
The Omsk oil refinery, operated by Gazprom Neft, has been operating since 1955 and has an annual processing capacity of around 22 million tonnes. It was first hit by Ukrainian drones on 6 July 2026, in an attack attributed to the Special Operations Forces' Deep Strike unit; the strike damaged primary processing units and forced the plant to halt operations, and Russian oil refining reportedly fell to its lowest level since 2002 in the aftermath. On the morning of 8 October, Omsk authorities restricted mobile internet and closed Omsk airport in anticipation of a drone attack, before residents reported multiple explosions near the refinery and queued at petrol stations after air-raid sirens.
