Ukraine has intensified its drone attacks on critical Russian industrial sites, with recent strikes including significant hits on oil refineries in Ryazan and other regions. The latest offensive resulted in massive fires at key oil industry locations, including a Russian microchip factory that has now halted production. As Ukrainian drones target various military and industrial hubs, reports indicate a pivotal shift in the tactics employed, causing unprecedented damage and prompting emergency responses from Russian defense forces. Videos circulating online show the aftermath of these drone strikes, illustrating the scale of the destruction and the increasing vulnerability of Russian facilities to aerial assaults. Ukrainian military officials claim to have successfully hit multiple targets, including oil depots and a military aviation plant, amid reports of defensive systems failing to intercept the incoming threats.
