Ukrainian drones struck Russia's Surgut gas condensate plant in the Khanty-Mansi Autonomous Okrug, about 2,500 kilometers from the Ukrainian border, sparking a fire at the facility on October 16, according to Russian officials and Ukrainian sources. The strike came as Russia's Ryazan oil refinery shut down one of its primary crude distillation units following a separate drone attack, and as Moscow's airports suspended flights for multiple nights in a row, diverting more than 20 inbound aircraft, amid special monitoring of the region's aviation. President Vladimir Putin vowed retribution for Ukrainian strikes on Russian data centers while downplaying damage to the refineries, also acknowledging that Russian security services failed to anticipate attacks on commercial logistics hubs such as Wildberries and Ozon.
