Ukraine launched one of its largest deep-strike operations of the war overnight Saturday, striking an oil terminal and a nearby naval facility in and around St. Petersburg, Russia's second-largest city and President Vladimir Putin's hometown. St. Petersburg Governor Alexander Beglov said drones hit an oil terminal in the city's Kirovsky district and that one drone crashed within the grounds of the historic Peterhof Palace complex, while air defenses shot down 72 drones over the city and surrounding region. President Volodymyr Zelenskyy confirmed the operation, describing it as part of Ukraine's "long-range sanctions" campaign against Moscow. "The Ukrainian defense forces hit the port oil infrastructure, which earns money for the Russian war, and there were also hits on Kronstadt β€” an important military target," he wrote on Telegram, referring to a naval base on an island just off St. Petersburg. Ukraine's Special Operations Forces said the strikes, conducted jointly with the Unmanned Systems Forces, military intelligence and the security service, reached targets located more than 850 kilometers from the Ukrainian border and set off a fire at the terminal, which has an annual processing capacity of 12.5 million tons and serves as a major Baltic export hub for Russian oil. Drone debris also fell near the Baltic port of Vysotsk, close to the Finnish border, according to Leningrad region Governor Alexander Drozdenko. Elsewhere, Russian forces struck the Crimean peninsula, killing one person and injuring two others, including a 10-year-old child, according to Moscow-installed officials, while Russia separately reported casualties in Bryansk and disruptions to power and water in Belgorod. In response, Russia struck a Ukrainian gas production facility in the central Poltava region, sparking a fire and forcing a suspension of operations there, according to state energy firm Naftogaz, which said the attack was part of a deliberate effort to curb Ukraine's domestic gas output ahead of the coming heating season. According to Ukraine's General Staff, the sustained campaign against Russian energy infrastructure has now disabled nearly 43% of the country's oil refining capacity as of early July, with eight refineries struck and more than 60 storage tanks destroyed or damaged over the past month alone, contributing to cumulative industry losses Kyiv estimates at $13.5 billion since August 2025. Putin has dismissed the strikes as "not critical" to the war's trajectory, characterizing them as an attempt to distract from Ukrainian losses on the battlefield. Russia separately claimed Saturday to have captured four villages in Ukraine's Kharkiv region and one in Donetsk, along with the strategic eastern town of Kostiantynivka a day earlier β€” a claim Zelenskyy has firmly denied, calling it "another Russian lie." The exchange comes just ahead of a NATO summit in Ankara next week, where member states are expected to pledge roughly €70 billion in further military assistance to Ukraine.
