Aug. 24 (UPI) -- Ukraine targeted Russia's second-largest online retailer, Ozon, with drone strikes on four of its warehouses on Monday.

Ozon says logistics facilities in Krasnodar, Dagestan, Stavropol and Adygea were set ablaze by the strikes with several people reported injured. Ukraine had previously targeted Russia's largest online retailer Wildberries with drone strikes, hitting 15 of its logistics hubs.

Ukrainian officials said Wildberries was considered a legitimate target because it supplies the Russian military. Russia denies this claim.

Ozon evacuated warehouses in Adygeysk and Nevinnomyssk due to the threat of potential drone strikes.
