Russian authorities reported that Ukraine launched a large-scale drone attack on the Leningrad region surrounding St. Petersburg on June 6, 2026, the final day of the St. Petersburg International Economic Forum (SPIEF). Governor Alexander Drozdenko stated that over 140 drones were shot down, calling the assault 'unprecedented' in scale. No casualties or major damage were immediately reported.
The attack targeted areas near the city, which is hosting the annual economic forum attended by Russian officials and international delegates. This marks one of the deepest and most significant drone strikes inside Russian territory since the conflict began, highlighting Ukraine's expanding drone capabilities.
Ukrainian officials have not officially commented on the operation, but sources suggest it was aimed at disrupting the forum and demonstrating Kyiv's ability to strike far from the front lines. The Russian Defense Ministry confirmed the interception of the drones, emphasizing that air defense systems were activated across the region.
The incident underscores the ongoing escalation in the war, with both sides increasingly relying on drone warfare. The attack occurred as SPIEF concluded, with Russian President Vladimir Putin having addressed the forum earlier in the week, focusing on economic resilience despite Western sanctions.
