Ukraine has regularly hit targets in the distant Urals and has even struck a Russian oil refinery in western Siberia, nearly 2500km from the border. A Wildberries warehouse in Yekaterinburg, Russia's fourth-largest city, was set ablaze by the attack, the company said. Officials said three drones hit the warehouse's roof, while 800 people were evacuated from the warehouse but nobody was hurt. In Ukraine's northern Sumy region, a Russian drone struck a busy market Friday morning, wounding 10 people, authorities said.
