**Deck**: A refinery fire in Ufa, one of Russia’s key fuel hubs, followed a reported drone strike and came a day after a large attack on the Novokuybyshevsk plant. Ukrainian-linked sources say the strikes mark a renewed campaign against refineries that produce gasoline, diesel, lubricants and aviation fuel for Russia’s military and domestic market.

A fire at a refinery in Ufa, deep inside Russia, has become a fresh marker of Ukraine’s long-range drone campaign against Russian energy infrastructure. The incident adds pressure on a hub that helps supply fuel for Russia’s military operations and for civilian use.

Ukraine-linked and Russian reports on 31 October pointed to overnight drone strikes on targets in Russia, including the Ufa oil refining complex in Bashkortostan. Footage from the scene shows a fire at the plant. Ukraine-focused sources said the L‑35 catalytic reforming unit was burning, describing it as a unit that produces high-octane gasoline components and hydrogen used in other refinery processes.

Observers following the conflict say Ukraine has “clearly restarted” its refinery campaign, noting that the Ufa incident came just one day after a large-scale strike on the Novokuybyshevsk refinery. Ukrainian information channels present these operations as a deliberate effort to disrupt Russia’s capacity to produce gasoline, diesel, lubricants and aviation fuel consumed across Russia and in occupied territory. Russian authorities have acknowledged drone attacks and fires but, by mid-morning, had not detailed the extent of damage at Ufa.

In Bashkortostan and surrounding regions, even a temporary disruption at Ufa can tighten fuel supplies and complicate logistics. Workers at such facilities now face industrial risks that include not only routine safety hazards but also incoming drones and potential secondary explosions. Refined products from hubs like Ufa feed truck transport, agriculture and emergency services in western Russia, so outages force Moscow to adjust internal supply and weigh how to prioritize military needs.

The strikes also stretch Russia’s air defenses. Ufa lies roughly 1,300–1,500 kilometers from Ukraine, depending on where drones are launched. That distance underlines the reach of Ukrainian-made systems. Russia’s Defense Ministry claimed overnight that its forces shot down 433 Ukrainian UAVs over various regions while noting that the Ufa refinery was among the targets. The interception figure indicates the scale of the Ukrainian drone effort and the resources Russia is now committing to defend its own territory.

Each successful hit on a refinery complicates Moscow’s management of fuel flows between the front and the home market. When facilities such as Ufa and Novokuybyshevsk are forced to halt or reduce operations, even briefly, authorities may need to draw on storage, reroute supplies from other regions or adjust export volumes to keep domestic markets supplied. Even limited but repeated damage to key units can unsettle planning in Russia’s energy administration and military logistics.

The refinery strikes have a diplomatic angle. Russian-aligned outlets note that “the U.S. side has made no response” to the deep attacks, hinting that Washington could try to influence Kyiv’s choices. Ukraine-facing commentary, in turn, stresses that U.S. intelligence support has been important for long-range Ukrainian operations since early in the full-scale war. Western governments have generally avoided clear public positions on attacks inside Russia while maintaining support that enables Ukrainian targeting.

The fire in Ufa underlines how energy sites function as both economic infrastructure and part of the wider war effort. As Ukrainian drones reach plants hundreds of kilometers from the border, it becomes harder for Russia to separate the interior of the country from the battlefield.

Key developments to track now include how long affected units at Ufa remain offline, any changes in Russian fuel export rules or domestic pricing, and whether Ukrainian drones continue hitting refineries night after night. Insurance and freight costs for Russian fuel cargoes moving from Black Sea and Baltic ports will offer further clues as to whether markets see refinery-targeted strikes as a lasting feature of the conflict.
