Russia accused Ukraine of targeting Wildberries warehouses overnight on Wednesday for the second time in a week, after drones were heard and fires broke out at warehouse sites in the Krasnodar and Stavropol regions, according to authorities.

Wildberries founder Tatyana Kim — described by domestic outlets as Russia's wealthiest woman — said employees had been evacuated in advance, but that 15 people were injured, 10 in Krasnodar and five in Nevinnomyssk. Kim said several employees were taken to hospital, while others were treated at the scene.

Regional authorities declared a local state of emergency, saying the fires were extensive. Russia's Ministry of Emergency Situations said helicopters had been deployed to help extinguish the blaze.

Miratorg, Russia's largest meat producer, separately said three of its plants in the western Bryansk region were also targeted overnight, with a security guard injured and significant damage to one facility.
