Ukraine Strikes St. Petersburg and Kronstadt for Second Time in a Week — Russia Claims 376 Drones Intercepted Overnight — Day 1,563

On June 6, 2026 — Day 1,563 of Russia's full-scale invasion — Ukraine launched its largest single drone campaign of the war against the St. Petersburg area, striking the Kronstadt naval base, an oil complex, and other naval facilities for the second time in four days (the first strike on June 3 was timed to the opening of SPIEF, Russia's Davos; the June 6 strike came as the forum was closing with ~20,000 guests from 130+ countries still present). Russia's defense ministry and regional governor Aleksandr Beglov claimed 376 Ukrainian drones were intercepted overnight across 16 Russian regions, including 86 in the Leningrad region alone — numbers suggesting the largest single Ukrainian drone offensive of the war to date. St. Petersburg residents were told to stay indoors; explosions were reported near Kronstadt and in the city's northeast industrial districts. Videos circulating on Telegram showed large fires at oil and port facilities. Separately, Ukrainian drones reached approximately 500 km into Krasnodar region, striking an oil depot and causing large fires. By June 2026, Ukraine's 2026 drone campaign had struck 174 Russian air defense systems at an estimated cost to Moscow of $5.4 billion. The dual strike on St. Petersburg — Russia's second-largest city and cultural capital — during the closing of SPIEF represented a deliberate strategic messaging operation: demonstrating that no Russian city is safe regardless of how prominent an event is taking place.
