Ukrainian forces launched a large-scale drone assault on Russian energy infrastructure overnight on 10 July, striking the Ilsky and Kapotnya refineries, oil storage depots in the Rostov region, the port of Taganrog, and multiple tankers in the Sea of Azov. Russian authorities confirmed fires at several sites, evacuated residents from Taganrog, and reported that air defences downed 376 drones across 13 regions. The Ukrainian General Staff claimed hits on the Ust-Luga refining complex in the Leningrad region and said nearly 50 fuel-transport vessels had been damaged in the Azov Sea over the past week.

Kyiv frames the strikes as part of a “long-range sanctions” campaign, according to President Volodymyr Zelensky, designed to curtail fuel supplies to Russian forces and isolate occupied Crimea. Moscow, through Defence Ministry statements and regional governors, described the attacks as terrorist acts and insisted that most drones were intercepted. The Kremlin acknowledged that the strikes are causing fuel shortages, with President Vladimir Putin stating they aim to divide Russian society. In Washington, the White House announced a licence for Ukraine to manufacture Patriot air-defence systems, a move the Kremlin called “ambivalent” but said it appreciated US peace efforts.

The attacks have deepened a nationwide fuel crisis. Long queues formed at petrol stations in Moscow, and several regions imposed rationing. Russia’s government banned diesel exports earlier in the week to safeguard domestic supply for military vehicles. The International Energy Agency (IEA) revised down its forecast for Russian oil output, explicitly citing the “ongoing attacks on refineries, storage and transport infrastructure.” In the Azov Sea, the targeting of tankers—including vessels from the so-called shadow fleet used to circumvent sanctions—has disrupted logistics for fuel deliveries to Crimea and the southern front.

The strikes are the latest in a months-long Ukrainian campaign that has repeatedly hit Russian refining capacity. According to Ukrainian military sources, the Ilsky refinery alone has been attacked seventeen times. Despite the tactical successes, Ukraine’s commander-in-chief Oleksandr Syrsky cautioned that a turning point in the war “is still a long way off.” US-mediated negotiations remain stalled, with Moscow linking any progress to the establishment of a “security zone” around Kyiv. The next known step is the expected delivery of US-made interceptor missiles for Patriot systems to Ukraine in the coming days, while domestic production of the systems is projected to take at least a year.
