The governor of the southern Samara region said on Saturday that Ukrainian drones hit an industrial facility, as well as a warehouse belonging to online retailer Ozon, in overnight strikes.

In a post on Telegram, Governor Vyacheslav Fedorishchev said that several people were wounded in the strikes. He did not name the industrial facility that was struck, but the region hosts several oil refineries that have been repeatedly attacked by Ukraine.

Ozon, Russia's second-largest online retailer, said in a statement on Telegram that work at its Samara region logistics center in the town of Chapayevsk had been halted after the strike, which it said caused injuries.

The strike is the first on Ozon so far, after weeks of attacks targeting its larger rival Wildberries, which Ukraine has cast as part of a wider campaign against economic infrastructure underpinning Russia's military campaign.

Russia's Defense Ministry said it downed 457 Ukrainian drones overnight.
