Ukraine's military conducted an overnight drone strike on a major oil terminal in St Petersburg and a Russian naval base in the surrounding region, located approximately 850 kilometres from Ukraine's border. St Petersburg's governor confirmed the oil terminal was hit and reported that 72 Ukrainian drones were intercepted over the city, with no casualties. Ukraine's president described the terminal as a key source of revenue for Russia's war effort and among the largest in the country, capable of processing 12.5 million tonnes of petroleum annually.

The strike represents an escalation in Ukraine's campaign against Russia's energy infrastructure, which Kyiv claims has disabled nearly 43% of Russian oil refining capacity, though this figure remains unverified. Ukraine argues that such facilities are legitimate military targets because Russia depends heavily on fossil fuel exports to fund its war effort. The attack occurred as Russia faces mounting fuel shortages, prompting President Putin to sign legislation aimed at boosting domestic fuel supply. Additionally, the two nations remained in dispute over control of the eastern town of Kostyantynivka, with Ukraine's military denying Russian claims of full control established in June.
