Ukraine launched drone attacks targeting a major Russian oil refinery, a Black Sea oil terminal, and a power substation supplying occupied Crimea. The attacks resulted in fires at all three locations and triggered a widespread power outage across Crimea, disrupting electric transport in multiple cities. This action represents a significant escalation in Ukraine’s campaign to degrade Russia’s logistical and energy capabilities. The targeting of the power substation specifically aims to impact the electricity supply to the annexed peninsula. Russia has not yet officially commented on the extent of the damage or the cause of the blackout, but Ukrainian sources confirm the successful strikes. These attacks suggest a continued Ukrainian focus on striking deep within Russian-controlled territory. The disruption to Crimea’s power grid will likely impact both military and civilian infrastructure.
