More warehouses of Russian online retailer Wildberries hit by Ukraine, officials say

Watch: Warehouses on fire after Ukraine hit Russian online retailer

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 were 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 on Saturday, 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 confirmed the attacks on two 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.

Footage of both warehouses, verified by BBC Verify, shows fires in the aftermath of the attacks.

Video from Krasnodar captures an enormous column of black smoke rising from the structure as flames leap upwards. Nevinnomyssk footage shows people milling around outside as fireballs erupt in smoke streaming from the building.

Krasnodar's governor said the region was hit by a "massive attack last night", with drone debris also hitting the grounds of a company in Armavir and killing one employee. The city administration reported that an oil depot was struck, causing a fire.

Drone fragments also hit two apartment buildings in Krasnodar and two homes in the village of Dinskaya, Kondratyev said. There were no injuries.

Zelensky said Ukraine had struck an oil depot, as well as a tanker and four cargo ships of the Russian shadow fleet in the waters of the Sea of Azov and Black Sea.
