Ukrainian forces conducted a drone attack on a Russian oil refinery located approximately 800 kilometers from the border, triggering fires at the facility. Russia described the strike as unprecedented. Ukraine also targeted oil infrastructure in St. Petersburg and Crimea, with fires reported at multiple locations.
The long-range operations reflect Ukraine's growing ability to conduct strikes against strategic targets deep within Russian territory. These attacks have disrupted Russia's capacity to supply military and civilian resources to occupied territories, intensifying fuel shortages across Russian-controlled areas.
