Ukraine strikes St. Petersburg oil terminal and naval base as Putin's economic forum opens

Ukrainian drones struck an oil terminal and a naval base in St. Petersburg on June 3, 2026, hours before Vladimir Putin's flagship economic forum opened. The attack, which hit targets over 1,000 km from Ukraine, caused a large fire and disrupted flights, embarrassing the Kremlin as it sought to project economic strength to international guests. The strike followed a deadly Russian barrage on Ukraine the previous day.
