Ukrainian drones have struck warehouses and distribution hubs belonging to Ozon, Russia's second-largest online marketplace, for the third night in a row. The e-commerce site has become the latest target in Kyiv’s campaign of long-range drone strikes on Russian logistics and economic facilities, which Ukraine says help sustain Moscow's war effort. Russian authorities and the retailer reported attacks on its facilities overnight. Ozon said its logistics hub in Makhachkala, in Russia's Dagestan region, caught fire after a drone attack on Monday. The company also temporarily shut two warehouses in nearby Stavropol and Adygea amid drone alerts, although it said they were not damaged. A fire was also reported at an Ozon facility in Nevinnomyssk in the Stavropol region. Regional Governor Vladimir Vladimirov said Russian air defences were repelling a drone attack on the city's industrial area. The latest strikes follow attacks on Ozon facilities in Samara on Saturday and Orenburg on Sunday. The Samara hub, one of Ozon's largest, covers about 135,000 square metres and can process more than 215,000 orders a day. Ukraine has also repeatedly targeted Wildberries, Russia's largest online retailer, in its broader campaign against logistics infrastructure. Dual-use goods The strikes are part of Ukraine's effort to disrupt Russian rear logistics and the economy supporting its war effort, more than four years after Moscow launched its full-scale invasion. Ukrainian officials have said logistics centers are used to move dual-use goods and other supplies. Russia also reported casualties in Monday's attacks. Two children were killed and nine people, including seven children, were injured after drone debris struck a private childcare center in Krasnodar, regional Governor Veniamin Kondratyev said. Debris also fell on residential buildings and warehouses caught fire, he said.
