Ukraine launched a significant overnight attack targeting Russia’s second-largest oil refinery, as well as an airfield and drone launch site. This is not the first time the refinery has been struck, having been repeatedly targeted throughout the full-scale war. The attacks are part of Ukraine’s strategy to degrade Russia's ability to wage war by disrupting its economic and logistical support systems. By hitting key infrastructure, Ukraine aims to hinder Russia’s military operations. The strikes demonstrate Ukraine's capability to reach deeper into Russian territory and sustain attacks on critical facilities. Further details regarding the extent of the damage are still emerging, but the attacks signal an escalation in Ukraine’s counteroffensive tactics.
