The aerial assault targeted the Primorsk oil port in the Leningrad region, the final station of the Baltic Pipeline System and a crucial hub for Russia's maritime exports, Ukraine's security services told multiple outlets. More than half of the 221 drones sent to Russian territory were intercepted over the Bryansk and Smolensk regions, where Lukoil facilities were also reportedly targeted, the Russian defence ministry said. Meanwhile, officials said two civilians were killed in Ukraine's Sumy region when a Russian glide bomb struck a village near the border. Authorities in the Leningrad region said 28 drones were brought down and that a fire had broken out at a vessel and a pumping station in Primorsk. They added that the blaze was extinguished without casualties or leaks. The port is also central to Russia's so-called "shadow fleet" of ageing tankers used to skirt international sanctions.

The Ukrainian security services said drone strikes also hit several pumping stations feeding the Ust-Luga terminal, near the border with Estonia. Russian state energy firm Rosatom reported a drone attack on a power unit at its Smolensk Nuclear Power Plant, near the Belarussian border. Russian officials said drones were intercepted across at least nine other regions, including Kaluga, Novgorod and the Moscow area, where nine drones were said to have been destroyed. Debris was recorded across several areas, though authorities insisted there had been no casualties. (BBC)
