Ukraine Hits Moscow Refinery Twice in Three Days, Piercing Capital's Air Defense

Ukrainian drones struck the Moscow Oil Refinery in Kapotnya on June 18, 2026—the second attack in three days—igniting a fire and injuring 16 people. The refinery sits inside Moscow proper, one of Russia's most heavily defended airspaces. The repeated strikes within a narrow window signal sustained targeting, not chance penetration. Ukraine's ability to reach critical infrastructure at the capital's core raises questions about the actual coverage of Russian layered air defenses.
