Ukrainian drones struck the Omsk oil refinery in western Siberia on Saturday, targeting Russia’s largest fuel production facility.
The attack, located more than 2,500 kilometers from the front lines, marks a significant escalation in Kyiv’s ability to strike deep into Russian territory.
The strike disrupted operations at a critical node in Russia’s energy infrastructure, raising immediate concerns about potential disruptions to global fuel supplies.
The incident coincides with heightened diplomatic pressure on Moscow.
Kazakhstan’s president told Russian President Vladimir Putin that the war in Ukraine should end, signaling growing unease among neighboring states regarding the conflict's spillover effects.
The drone strike also disrupted a Urals athletics competition, underscoring the broadening scope of the conflict beyond traditional military targets.
