A drone attack triggered a fire at Russia’s Baltic Sea port of Ust-Luga, a major hub for oil and oil-products exports, after Russian authorities said 51 drones were shot down over the Leningrad region overnight. Governor Alexander Drozdenko said authorities first declared a drone threat across the region as air defense operations began, later reporting successive counts of 15, then 37, and finally 51 drones downed. He said damage from the attack caused a fire at the port of Ust-Luga, where specialists began extinguishing the blaze before the governor later said the drone threat had been eliminated. The extent of the damage was not immediately clear. The strike fits Ukraine’s broader campaign of targeting Russian oil processing and export facilities, as well as grain shipping routes, to cut revenue to Moscow and increase pressure over the war. The wider regional security impact was visible the same day: Latvia said a drone was shot down after entering its airspace, and Finland temporarily restricted parts of the Baltic Sea as a precaution. In Moscow, Mayor Sergei Sobyanin said more than a dozen drones heading toward the capital were also downed overnight.
