A long-running campaign of Ukraine refinery strikes has disabled 51% of Russia's oil refining capacity, according to an assessment released by Ukraine's Defense Ministry late Sunday. The claim, which could not be independently verified, in a war that has increasingly targeted the energy infrastructure both sides rely on. Recent strikes hit refineries and related facilities in Moscow, Yaroslavl, Ust-Luga, Perm, Saratov and Syzran, the ministry said, as part of a deliberate strategy to bleed Russia's war economy during the fourth year of its full-scale invasion.

The latest estimate represents a sharp escalation in Kyiv's public accounting of the Ukraine refinery strikes. On September 21, Ukraine's General Staff said Russian refining capacity had fallen by about 45% after months of strikes, according to reporting by the Associated Press and The Independent. Ukraine's Defense Ministry added that it had tripled the production and procurement of long-range strike drones this year, giving its forces the reach to hit energy targets deep inside Russian territory. Analysts from Ukraine's intelligence services, the General Staff and the Defense Ministry jointly assessed the cumulative damage, the ministry said.

The strikes come as the ground war has largely frozen in place. With progress along the 1,200-kilometer front line essentially halted, Moscow and Kyiv have both intensified long-range aerial assaults, trading drone and missile barrages aimed at industry, infrastructure and energy sites far from the trenches. For Ukraine, refineries are legitimate military targets: officials argue the Ukraine refinery strikes target facilities that finance Russia's war effort and supply fuel to its forces, a rationale Kyiv has stated openly in government communications.

Fuel crisis deepens inside Russia

Inside Russia, the effects of the Ukraine refinery strikes are already visible at the pump. Repeated Ukrainian attacks on refineries stretching from Moscow to Siberia sparked a widespread fuel crisis earlier this year that forced authorities to restrict gasoline sales, according to the Associated Press. The International Energy Agency estimates that Russian diesel output has fallen by about 30%, while drivers in some regions have faced waits of up to 40 hours at petrol stations, energy analysts report. Some facilities have been struck several times, forcing emergency repairs and operational changes that have kept capacity offline for extended stretches.

Russian officials have not publicly released detailed figures on the damage to the country's oil infrastructure. But in a rare acknowledgment of the Ukraine refinery strikes' economic impact, President Vladimir Putin said at a Valdai Club forum of international foreign policy experts that the campaign had cost Russia roughly one percent of its gross domestic product. They started attacking oil refineries and openly declared the goal of damaging the economy, Putin said in a statement reported by the Associated Press, adding that Kyiv had achieved that goal partially. The admission was striking for a leader who typically minimizes the impact of Ukrainian operations on Russian soil.

Kyiv presses the campaign as retaliation looms

Ukraine showed no sign of slowing the campaign. President Volodymyr Zelenskyy said Ukrainian forces had struck two oil facilities and a training ground in the Perm, Samara and Astrakhan regions over the past day, framing the Ukraine refinery strikes as a direct response to Russian strikes on Ukrainian cities, according to a post on social media. Separately, a Ukrainian drone attack killed one person and injured six in the Moscow region, the regional governor Andrei Vorobyov said on Telegram, after air defenses intercepted most of the drones launched toward the capital overnight. Russia, in turn, has kept up near-daily bombardments of Ukrainian cities, including a massive overnight barrage that Kyiv said killed civilians and damaged energy infrastructure.

The refinery campaign has also become a talking point in American politics. President Donald Trump wrote on Truth Social that Ukraine's strikes on Russian refineries are what is driving up gasoline prices, rather than the separate conflict involving Iran, and claimed that Democratic-led states are compounding the problem by closing domestic refineries. The statement drew pushback from energy analysts, who said broader forces, including the war in Iran and disruptions in global oil markets, remain the primary drivers of fuel costs. Ukraine refinery strikes have nonetheless entered the domestic debate over pump prices in the United States.

Whether the pressure will force negotiations remains an open question. Zelenskyy has advocated for a United States-mediated energy ceasefire that would halt the Ukraine refinery strikes and Russian attacks on both countries' energy infrastructure, but Putin has shown little interest in such talks, analysts say. Ukrainian military analyst Mykola Bielieskov told reporters there is no rationale for Kyiv to exercise restraint while its cities are under bombardment, arguing that depriving Russia of revenue-generating resources is strategically necessary. Russia has historically ranked as the world's third-largest producer of refined fuel products after the United States and China, so prolonged damage to its refining base could reshape global diesel and gasoline markets well beyond the battlefield.
