In one of the most extensive aerial assaults in recent months, Ukraine launched 221 drones overnight targeting multiple Russian regions, including energy infrastructure and port facilities, Russian defense officials reported on Friday. The attack marks a significant escalation in Kyiv’s use of long-range drone capabilities as the war enters its fourth year.
Russian authorities claimed to have intercepted the majority of the drones, though several reached their targets, including an oil terminal in a key Baltic port. Meanwhile, Russian forces continued offensive operations along the border, killing at least two civilians in Ukraine’s Sumy region with a glide bomb strike.

Large-Scale Drone Offensive
According to the Russian Ministry of Defense, Ukrainian drones targeted at least nine regions, including Bryansk, Smolensk, Leningrad, Kaluga, Novgorod, and areas near Moscow. More than half of the drones were shot down over the Bryansk and Smolensk regions, where energy infrastructure, reportedly including Lukoil facilities, was struck.
In the Leningrad region, 28 drones were intercepted. Authorities confirmed a fire broke out on a vessel at the port of Primorsk, Russia’s largest oil terminal, though it was extinguished without reported casualties or leaks.
Civilian Impact and Russian Response
In Bryansk, a drone struck a bus, injuring seven people, including five civilians and two military personnel, according to regional Governor Alexander Bogomaz. Despite widespread debris falling across several regions, Russian officials stated there were no fatalities on their territory.
The scale of the attack prompted temporary suspensions of operations at St. Petersburg’s Pulkovo Airport and drew significant defensive resources from Russian air units.
Strategic Context and Escalation
Thursday’s assault represents one of Ukraine’s largest drone operations since May 7, when Russia claimed to have downed a record 524 drones. Cross-border drone raids have become increasingly frequent as Ukraine leverages asymmetric capabilities to strike strategic targets deep behind Russian lines, including refineries, logistics hubs, and military infrastructure.
The attack also comes just days after a significant number of Russian drones violated Polish airspace, leading to heightened alert levels across NATO’s eastern flank. In addition, Russia and its ally Belarus are set to begin a major joint military exercise on Friday, held every four years but closely watched this year given regional tensions.
Ongoing Air War
While Ukraine has expanded its use of long-range drones, Russia has also intensified its aerial campaigns against Ukrainian cities and energy targets. Ukrainian officials reported that Russia deployed 818 drones against Ukraine in recent weeks, underscoring the reciprocal and escalating nature of aerial warfare.
As diplomatic efforts remain stalled, both sides are increasingly relying on strategic strikes aimed at damaging military and economic infrastructure, a sign that the conflict is continuing to expand in scope and intensity.
