**Deck**: Ukrainian drones reportedly hit an oil refinery in Ufa, more than 1,500 km from the border, and set fuel tanks ablaze at the Poltavskaya depot in Russia’s Krasnodar region in the second strike there this month. The expanding reach of Kyiv’s drone campaign is turning Russian energy assets far from the front into a battlefield, with implications for supply, insurance and Moscow’s sense of rear-area security.

Russia’s oil network is learning a lesson Ukraine has known for years: distance from the front line is no longer a guarantee of safety. Reported Ukrainian drone strikes on facilities in both Bashkortostan and Krasnodar show that energy infrastructure deep inside Russia can now find itself on the edge of the war.

On 25 June, regional emergency officials in the Russian republic of Bashkortostan said an explosion occurred at the Novoil oil refinery in Ufa after a drone attack, adding that no one was injured. Separate footage and reports circulating the same morning described a Ukrainian long‑range drone strike on a refinery in Ufa, more than 1,500 kilometers from the Ukrainian border. While attribution from Kyiv was not immediately available, the geography points to a deliberate attempt to demonstrate extended reach into Russia’s industrial heartland.

At nearly the same time, officials in Russia’s southern Krasnodar region reported that Ukrainian drones had struck the Poltavskaya oil depot for the second time this month, igniting at least three fuel tanks. Russia’s Defense Ministry claimed overnight that its air defenses had shot down 269 drones, but acknowledged multiple attacks and fires at energy facilities. The scale of the claimed shootdowns suggests a large‑scale effort by Ukraine to saturate Russian air defenses with unmanned systems, accepting some losses to ensure that enough drones reach high‑value targets.

For Russian workers and communities around these sites, the immediate concern is straightforward: fires, explosions, and the risk of toxic smoke. Even when officials report no casualties, refinery and depot staff are operating in conditions where alarms can signal not just industrial accidents but incoming enemy drones. Residents in nearby neighborhoods see flames on horizons that were once industrial but not military.

Operationally, each damaged refinery unit or destroyed fuel tank forces Russia to adjust logistics. Oil companies must reroute crude, shift product flows or lean on alternate depots, raising transport costs and straining rail and pipeline capacity. Military planners face a parallel problem: fuel destined for air bases, armored units or logistics hubs must still move, often along routes increasingly monitored — and targeted — by Ukraine.

Strategically, the strikes fit a broader Ukrainian effort to impose costs on Russia well beyond the trenches, targeting assets that support both the economy and the war machine. Oil refineries and storage depots are especially attractive because they are fixed, difficult to hide and essential to keeping both civilian transport and military operations supplied. Hitting facilities more than a thousand kilometers from the border also sends a message to Russian society and investors that the war’s perimeter is porous.

For global markets, the near‑term impact of a handful of refinery or depot fires remains limited, especially while crude prices are easing and more tankers are traversing the Strait of Hormuz. But the risk premium is creeping in elsewhere: insurers must reassess exposure on Russian energy infrastructure, and some buyers will weigh the reliability of supplies refined or shipped from repeatedly targeted regions.

Ukraine’s use of long‑range drones also carries a signaling function toward its backers. By demonstrating the ability to strike strategic assets deep inside Russia, Kyiv reinforces its argument that relatively inexpensive, domestically produced systems can produce outsized strategic leverage — provided it retains political latitude from partners who worry about escalation.

The key indicators to watch now are whether attacks on Russian energy infrastructure become more frequent, whether Moscow visibly hardens defenses around major refineries and export terminals, and whether any of these strikes begins to affect export volumes or domestic fuel availability. A sustained campaign that forces Russia to divert advanced air defenses from the front to the interior could quietly reshape the balance of protection over Ukrainian cities and troops.
