What happened

Ukraine's Special Operations Forces said drones traveling roughly 1,500km struck Gazprom Neftekhim Salavat, one of Russia's largest oil-refining and petrochemical complexes, hitting the critical AVT-6 primary distillation unit and triggering explosions and fire. Ukrainian reporting described it as the last major Russian refinery not yet struck during the 2026 campaign.
