A major Ukrainian drone assault on the Tyumen region in western Siberia has set Russia’s largest petrochemical facility ablaze marking one of the deepest strikes into Russian territory since the war began.

Drones Strike Deep Into Russian Heartland
Ukrainian drones reached far beyond the front lines on Monday crashing into an industrial facility in the Tyumen region of western Siberia. Local authorities confirmed a fire broke out after multiple drones hit the site. Tyumen region Governor Alexander Moor confirmed the strike but stopped short of naming the targeted facility. He also gave no word on casualties.
Russia’s Largest Petrochemical Plant in the Crosshairs
Unverified reports quickly pointed to the ZapSibNeftekhim plant Russia’s largest petrochemical complex as the target. The plant belongs to Sibur, a petrochemical giant, and sits in the city of Tobolsk. Tobolsk lies roughly 2,200 kilometres about 1,370 miles from Ukraine’s border. That distance makes this one of the farthest drone strikes Ukraine has reportedly carried out inside Russia.
Smoke Clouds Rise Over Tobolsk
Videos circulating on social media purportedly showed thick, dark plumes of smoke rising above the ZapSibNeftekhim plant. The footage spread rapidly online, though authorities did not immediately verify it. The scale of the visible smoke pointed to a significant fire at the petrochemical complex.
Ukraine Strikes Two Oil Refineries the Same Day
Earlier on Monday, Ukraine confirmed it struck two Russian oil refineries though it did not immediately claim the Tyumen attack. Kyiv has increasingly targeted Russia’s energy and industrial backbone as part of its long-range drone campaign. The ZapSibNeftekhim strike if confirmed would mark a major escalation in that strategy.
