Ukraine launched a daring long-range drone strike that hit the Petersburg Oil Terminal in St. Petersburg, Russia, producing visible fire and thick black smoke plumes during the opening of Russia's St. Petersburg International Economic Forum on June 3, 2026. The Ukrainian drone flew over 1,000 km to strike the Baltic Sea petroleum hub, marking a major escalation in attacks on energy infrastructure deep inside Russian territory.

Officials confirmed fires at the terminal and related disruptions including temporary flight suspensions, underscoring Ukraine's growing ability to strike high-value targets far behind enemy lines. The attack targets Russia's economic lifeline while sending a powerful message that no part of the Russian homeland is safe from Ukraine's defensive counteroffensive.
