Ukrainian Drones Set Fire to St Petersburg Oil Terminal Ahead of Putin Economic Forum Visit

Ukrainian drones set fire to an oil terminal in St Petersburg overnight ahead of a planned visit by President Vladimir Putin to the annual St Petersburg International Economic Forum (SPIEF) being hosted in the city. The drones flew approximately 1,000 km to reach the target. The strike is the latest in Ukraine’s long-running deep-strike campaign against Russian oil infrastructure and is operationally timed to embarrass the Kremlin during the showcase economic-diplomatic event. Russian forces continued large-scale missile and drone barrages on Ukrainian cities overnight.

The St Petersburg International Economic Forum (SPIEF) is the Kremlin’s flagship annual economic-diplomatic event, designed to showcase Russian openness to foreign investment despite Western sanctions. A Ukrainian drone strike on the host city’s oil terminal during the forum is calibrated for maximum embarrassment and indicates Ukrainian intelligence-led targeting of high-prestige Russian events. Ukrainian deep-strike operations against Russian refining and storage infrastructure have measurably affected Russian fuel availability through 2026, with Russian wholesale petrol prices spiking after multiple strikes. The strike follows the weekend hits on the Saratov Oil Refinery, a Caspian military base and a Rosneft refinery.
