Ukrainian drones struck the St. Petersburg area early Friday, the same day President Vladimir Putin is scheduled to address the city's flagship economic forum, an event designed to attract foreign investment. Black plumes of smoke were seen rising over Russia's second-largest city as dawn broke.

Authorities reported that air defense systems shot down 59 drones overnight, with impacts occurring in three different districts of St. Petersburg. While no fatalities were reported, the strikes occurred just hours before the opening of the St. Petersburg International Economic Forum (SPIEF), a crucial event for Russia's economic outreach.

Kremlin spokesman Dmitry Peskov stated that Moscow would retaliate, describing potential responses as "systemic in nature." Mobile internet services experienced disruptions, and Pulkovo Airport in St. Petersburg was temporarily closed. Air raid alerts were also issued in parts of neighboring Latvia and Estonia.

Ukrainian President Volodymyr Zelensky confirmed the drone operations, stating that Ukrainian drones had successfully targeted "several locations in Russia," including an oil terminal and a naval base in the nearby town of Kronstadt. He described the action as part of Ukraine's "long-range sanctions" plan to "bring peace closer."

Kronstadt serves as the primary base for the Russian Navy's Baltic Fleet. Social media channels associated with Ukrainian military figures shared unverified videos purportedly showing drones en route to military ships. Robert Brovdi, commander of Ukraine's unmanned systems, claimed on Telegram that the corvette Boikiy had been struck.

The St. Petersburg International Economic Forum, often referred to as the "Russian Davos," has historically been a significant platform for Russia to showcase its economic potential and attract international partners. Prior to Russia's full-scale invasion of Ukraine in 2022, the forum regularly saw participation from high-profile Western business leaders and government officials.

This year's forum marks a notable shift, with a U.S. delegation participating for the first time in nearly a decade. The delegation is reportedly led by Rodney Mims Cook Jr., head of the U.S. Commission of Fine Arts, who has been involved in overseeing projects at the White House.

The strikes highlight Ukraine's expanding reach in targeting Russian territory, demonstrating capabilities that extend to key industrial and military sites far from the front lines, even as Russia prepares to host an event intended to project stability and economic confidence.
