Ukraine Launches Drone Strike on Donetsk Building, Russian Forces Advance in Kostiantynivka

Ukrainian forces conducted a targeted drone attack on a building in occupied Donetsk, deploying eight drones against what appears to have been a high-value target, possibly linked to Russia's Federal Security Service (FSB). The precision of the operation and unusual silence from Russian authorities suggest the target held significant strategic importance. Meanwhile, Russian forces are making gradual advances into the eastern Ukrainian city of Kostiantynivka, where Ukrainian defenders report a shortage of drone operators. The developments come on the 1,520th day of the war, as fighting continues across multiple fronts in eastern Ukraine. Russian military reports acknowledge ongoing combat operations but claim limited territorial gains, while Ukrainian forces maintain their strategy of targeted strikes against military and intelligence infrastructure in occupied territories.
