Waves of Ukrainian drone attacks killed seven warehouse workers and injured at least 25 others, while a separate strike ignited a fire at an oil depot in the Moscow region, Russian regional governors said Saturday.

Tambov Gov. Evgeniy Pervyshov said Ukrainian drones struck a warehouse owned by Wildberries, Russia's largest online retailer, in the city of Kotovsk, about 475 kilometers (295 miles) southeast of Moscow. The attack killed seven workers and injured 25 others.

"Seven people working the night shift died on the spot," Pervyshov wrote on Telegram, adding that 28 drones also were shot down before reaching the warehouse.

"If they had achieved their goal, the number of civilian casualties could have been much higher," he said.

Ukrainian President Volodymyr Zelenskyy said Kyiv had struck two logistics facilities used by Russia to supply components for drone production and navigation equipment. An oil facility was also hit, Zelenskyy wrote on X.
