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.
