"Ukraine has launched one of its deepest drone strikes to date, hitting an oil refinery in central Siberia. Local authorities in Omsk confirmed the strike as emergency crews battle large fires at the industrial site. The Omsk facility is Russia's largest refinery and sits thousands of kilometers from the Ukrainian border. Military officials in Kiev say the operation also hit major oil export hubs on the Baltic Sea. These long-range strikes aim to disrupt Russian military fuel supply lines and weaken the Kremlin's energy revenues. Regional governors in Kaluga and Yaroslavl reported drone activity at several other strategic sites overnight."
