Several people have been wounded in Ukrainian drone attacks on St. Petersburg on the opening day of Russia’s largest investment forum, local governor Aleksandr Beglov reported Wednesday.

UAVs targeted infrastructure in the Kirovsky and Krasnoselsky districts as well as the port of Kronstadt, which is part of St. Petersburg, Beglov wrote on Telegram. Response teams have been deployed to facilities damaged by the attacks.

The 29th St. Petersburg International Economic Forum (SPIEF 2026), often referred to as the “Russian Davos,” runs from June 3 to June 6. This year’s event will gather approximately 20,000 businesspeople, politicians, and public figures from more than 100 nations. Russian President Vladimir Putin is scheduled to address the gathering on Friday.

In the Leningrad Region surrounding St. Petersburg, at least 59 Ukrainian drones were shot down overnight, local governor Aleksandr Drozdenko stated. Several private homes suffered minor damage from falling debris, but no injuries were reported.

The Russian Defense Ministry confirmed a total of 345 Ukrainian UAVs were intercepted across Russia during the night as part of another large-scale attack. The strikes occurred over Moscow, Leningrad, Belgorod, Bryansk, Voronezh, Kaluga, Kursk, Novgorod, Orel, Pskov, Rostov, Smolensk, Tver, Tula, and Krasnodar regions, as well as Crimea and the Sea of Azov.

In Russia’s Donetsk People’s Republic, seven civilians were killed and 11 others wounded when a Ukrainian drone struck a passenger bus traveling from Crimea to Moscow.

Ukrainian UAVs have repeatedly targeted Leningrad Region energy facilities in recent months, with explosive-laden drones often reaching northwestern Russia via Latvia, Estonia, Lithuania, and Finland—some crashing within NATO territories. Russian Security Council Secretary Sergey Shoigu previously warned that if the Baltic States and Finland “deliberately provide their airspace” to Ukrainian UAVs, Moscow retains the right to self-defense under Article 51 of the UN Charter.
