Ukrainian long-range drones hit a warehouse in the Ural Mountains belonging to Russia’s biggest online retailer, more than 2,000 kilometers (1,200 miles) from the two countries’ border, local officials and the company said Friday.Ukraine has regularly hit targets in the distant Urals this year and has even struck a Russian oil refinery in western Siberia, nearly 2,500 kilometers (1,550 miles) from the border. The attacks are examples of how Kyiv has used drone innovation as a key part of its response to the invasion by its much bigger enemy more than four years ago.Its successes have drawn international interest and drone cooperation agreements with nine countries, with further deals being negotiated with 15 other countries, according to Kyiv officials.A Wildberries warehouse in Yekaterinburg, Russia’s fourth-largest city, was set ablaze by the attack, the company said. Most merchandise wasn’t damaged, it said, unlike at some of the more than a dozen other Wildberries depots struck by Ukraine in recent weeks that have burned down. Kyiv is trying to rattle the Russian public and the Kremlin with the attacks.The regional governor, Denis Pasler, said three drones hit the warehouse’s roof. Artyom Zhoga, the Kremlin’s representative in the region, said that 800 people were evacuated from the warehouse and nobody was hurt.
