Ukrainian drones have hit warehouses belonging to Russia’s biggest online retailer again, injuring 15 people, according to the company’s founder and regional governors.

Logistics hubs run by Wildberries in two south-west cities were impacted by overnight attacks and workers evacuated, the founder said.

It is the second time Ukraine has attacked the firm’s facilities in four days, with warehouses in Tambov and Elektrostal hit over the weekend, killing eight people.

Ukrainian President Volodymyr Zelensky said on Wednesday that Ukraine had hit logistics hubs in the Krasnodar and Stavropol regions “involved in providing the Russian army with drone components, navigation equipment and other gear”.

Wildberries founder Tatyana Kim said workers were evacuated after the attacks on logistics centres in Krasnodar and Nevinnomyssk in the Stavropol region.

“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,” she wrote on Telegram. “But these situations demonstrate the most important thing: we must continue to do what we do for the benefit of people.”

Five people were hurt in a warehouse complex on the outskirts of Nevinnomyssk, Governor Vladimir Vladimirov said, with everyone receiving outpatient treatment.

In Krasnodar, ten people were injured in an attack on a warehouse complex, with three in a serious condition, the region’s governor Veniamin Kondratyev said.

BBC Verify has analysed footage and confirmed fires in the two locations.

Reports of the strikes first emerged just after 00:00 GMT, with the Russian state news agency TASS reporting that air defences had been activated in Nevinnomyssk. Dramatic footage filmed by locals began to emerge shortly after.

In both locations, the impact appears substantial, with large fires engulfing the buildings and huge columns of smoke rising into the air.
