Russia's second-biggest online retailer targeted in Ukrainian strikes

BBC News

Russia's second-biggest online retailer targeted in Ukrainian strikes Warehouses belonging to Russia's second-largest online retailer have been hit by a wave of Ukrainian drone strikes. Ozon said its logistics facilities in the southern regions of Krasnodar, Dagestan, Stavropol and Adygea were on fire and several people had been injured following overnight strikes. Ukraine has for weeks struck sites belonging to Wildberries, the country's biggest online retailer, describing the firm as a legitimate target because it supplied components to the military, which Moscow denies. Russian President Vladimir Putin said on Saturday that Ukraine had opened Pandora's box by striking economic targets and that Russia would hit back at Kyiv's most sensitive economic sectors. Russia has targeted Ukraine's civilian infrastructure since launching its full-scale invasion in 2022, and recent Russian attacks have hit Ukrainian warehouses and cargo terminals. Both Russia and Ukraine deny deliberately targeting civilians.


Ukrainian drones hit Russian online retailer Wildberries, media and governor say

BBC News

Ukrainian drones have hit warehouses belonging to Russia's biggest online retailer again, injuring 10 people, according to Russian media and the region's governor. Logistics hubs belonging to Wildberries in Krasnodar and Stavropol were struck during overnight strikes, forcing workers to be evacuated, the company's owner said. It is the second time Ukraine has attacked the firm's facilities in four days, with warehouses in Tambov and Elektrostal hit on Saturday, killing eight and injuring 62. Kyiv has claimed the warehouses have been used to supply components to make Russia's drones and navigation equipment. Wildberries owner Tatyana Kim said on Telegram that there are no words to describe all the feelings and emotions caused by the attacks on ordinary people, on our employees, on us, who are simply doing our jobs. But these situations demonstrate the most important thing: we must continue to do what we do for the benefit of people.
