Leningrad Region was struck by more than 50 Ukrainian drones overnight, according to its governor Aleksandr Drozdenko. A fire broke out at Russia’s key Baltic Sea port of Ust-Luga following the attack, which was extinguished after several hours with no reported fatalities or injuries.

The port area, home to Europe’s largest oil terminal and a major gas-processing complex, has been subjected to multiple Ukrainian drone strikes in recent months. St. Petersburg’s Pulkovo Airport also reported forced flight rescheduling due to aerial incursions by Ukrainian forces.

On Friday, Ukraine struck a residential building in Bryansk, western Russia, killing one person and injuring at least six others, according to the region’s acting governor Egor Kovalchuk. A separate drone attack in the village of Snytkino resulted in one injury.

The Russian Defense Ministry reported that 553 Ukrainian drones were shot down or intercepted across 19 regions overnight. Moscow has condemned the strikes on both infrastructure and civilian areas as deliberate acts of terrorism aimed at offsetting military setbacks suffered by Ukraine on the battlefield where Russian forces have maintained a steady advance.

In response, Russia has intensified its long-range missile and drone strikes against Ukrainian military-industrial facilities and logistics networks. The ministry stated that 14 such attacks occurred within the past week, targeting weapons production plants, supply depots, fuel and energy infrastructure, transportation hubs, military airfields, and ports where Ukrainian forces unloading cargo.

Additionally, Russian forces have targeted 15 oceangoing vessels linked to Ukraine’s military operations, including a tanker, seven dry cargo ships, two tugboats, and five patrol boats.
