A Swedish reconnaissance aircraft is actively monitoring the Russian border, focusing on the area near St. Petersburg, data from the flight-tracking platform Flightradar24 confirmed.


Observers noted that the surveillance flight was launched immediately following a Ukrainian drone strike on the port of Ust-Luga in Russia’s Leningrad region.


Ukrainian drones struck Russia's Baltic Sea port of Ust-Luga for the fifth time in 10 days, and industry sources said an oil loading terminal was hit, likely adding ​to Russia's difficulties in exporting crude.


Kyiv has stepped up attacks on Russia's ​oil export infrastructure over the past month, launching its heaviest drone ⁠strikes of the more than four-year war against the Baltic ports of Ust-Luga ​and Primorsk.
