Ukraine is intensifying strikes on Russia's energy infrastructure, targeting refineries, fuel depots and oil tankers in a campaign aimed at undermining the economic engine that has sustained Moscow's war effort. The strategy is piling pressure on Russia's fuel supply chain, with reports of shortages, rising prices and growing public frustration as the conflict enters its fifth year. Kyiv Hits the Kremlin Where It Hurts Analysts say Russia's vast energy sector has long financed its military campaign despite Western sanctions and mounting battlefield losses. Reuters analyst Mike Dolan argues that Ukraine is now attacking that critical vulnerability. Drone strikes on refineries and logistics hubs have disrupted fuel distribution, while reports suggest Russia has even turned to imports from countries including India and Kazakhstan to ease supply pressures. Economic Pressure Begins to Build The fuel disruptions have yet to dent Russia's military operations, but they are increasing strain on the wider economy. Dolan points to recent polling indicating Russians have become more pessimistic about their economic prospects than at any point in the past two decades. Whether that domestic pressure translates into political consequences for the Kremlin remains uncertain. Tankers Come Under Fire Ukraine has also expanded its campaign at sea, claiming to have struck multiple Russian oil tankers in the Sea of Azov over successive nights. According to Ukraine's Unmanned Systems Forces, drones damaged several vessels transporting fuel towards occupied Crimea. Ukrainian special operations forces said some of the tankers caught fire during the attacks, although the claims have not been independently verified. Crimea's Fuel Network Under Pressure If Ukraine's assessment proves accurate, the strikes could significantly disrupt fuel deliveries to Crimea, where supplies have already been tightened by earlier attacks on refineries and transport routes. The campaign highlights Kyiv's growing focus on logistics rather than territory alone. By targeting the fuel network that powers Russia's military machine, Ukraine appears determined to increase the economic and operational cost of the war, even as Moscow responds with intensified missile and drone attacks across Ukrainian cities. With neither side showing signs of backing down, the battle over energy infrastructure is emerging as one of the conflict's most consequential fronts, carrying implications far beyond the battlefield for regional security and global energy markets. Ukraine has found Russia's Achilles' heel — and is now targeting it relentlessly
