Ukraine has escalated its drone attacks on Russian oil refineries, targeting facilities in Krasnodar, Ilsky, Astrakhan, and Adygea, damaging infrastructure and causing fires. A significant attack hit the Ilsky refinery, one of Russia's largest, causing casualties and an extensive blaze. Additional strikes targeted radar stations and electronic intelligence centers in Bryansk and Crimea. Russia's Ministry of Defence reported intercepting several drones, but some still reached their targets, leading to a massive fire at an Enem refinery. These attacks form part of Ukraine's broader strategy to disrupt Russia's war economy by targeting its oil supply infrastructure. Meanwhile, Russia retaliated with renewed aerial assaults on Ukraine's power grid, impacting multiple regions including Kyiv and Donetsk.
