Russia’s Defence Ministry said on Sunday that its air-defence and electronic-warfare units destroyed 300 Ukrainian unmanned aircraft in the previous 24 hours and used warplanes, missiles and drones to strike multiple storage sites for Kyiv’s long-range Sapsan missiles. The ministry also reported improved Russian positions near Zolotyi Kolodiaz in the Donetsk region, where heavy fighting continues. Separately, the Federal Security Service (FSB) announced it had intercepted an aircraft-type drone over the Smolensk nuclear power plant, 330 kilometres southwest of Moscow, averting what it called a Ukrainian attempt to attack the Soviet-era facility. The plant said operations were unaffected and no damage was reported. Earlier in the day a Ukrainian drone struck the Liski railway logistics hub in Russia’s Voronezh region, about 160 kilometres from the border, injuring one rail employee and disrupting train traffic, according to regional governor Aleksandr Gusev. Ukrainian officials have not commented, but the hit marked at least the 16th attack on Russian rail infrastructure in the past month, according to Ukrainian analysts. Battlefield claims from both sides could not be independently verified, yet the incidents underscore the growing scale and reach of drone warfare as the conflict enters its fourth year, with each side seeking to degrade the other’s logistics while defending critical energy and transport assets.
