A Ukrainian drone attack on Tuesday, June 15th, ignited a fire at Moscow Oblast’s largest oil refinery, leading to a complete operational halt. The refinery is a crucial fuel provider for the Moscow region, and its suspension raises concerns about regional supply. Ukrainian sources have not yet officially claimed responsibility for the strike. Russian authorities confirmed the incident and are working to extinguish the blaze and assess the full extent of the damage. This attack represents a significant escalation in Ukraine’s targeting of Russian energy infrastructure. The disruption could potentially impact fuel prices and availability in the Moscow area. It is the latest in a series of reported drone strikes inside Russia.
