What happened

Several Ukrainian drones sparked a fire at an industrial facility in Russia's Tyumen region, Governor Alexander Moor said without identifying the site or reporting casualties. Ukraine's General Staff said its forces damaged part of SIBUR's ZapSibNeftekhim petrochemical complex in Tobolsk. In a subsequent address, President Volodymyr Zelenskyy described the operation as reaching more than 2,500 km and said Siberia was now within range of Ukrainian deep strikes. That figure is presented as Ukraine's operational-distance claim, not a measured straight-line distance from the border or front. The General Staff described the plant as producing components used in rocket and aviation fuels, drone composites and high-octane gasoline; those military-use claims and the specific target damage were not independently verified in the reviewed reporting. No affected unit, damage extent, production shutdown or casualty count was confirmed. The marker uses the documented coordinates of the ZapSibNeftekhim complex, not a verified impact point.

When cited sources give different casualty, damage or spill figures for this event, they’re reported side by side above rather than merged into one number. See how confidence levels work.
