Waves of Ukrainian drone attacks killed seven warehouse workers and injured dozens more, ​while another attack sparked a fire at an oil ‌depot in the wider capital region, regional governors said on Saturday.

Governor Evgeniy Pervyshov said 25 people were injured after Ukrainian drones slammed into a ​warehouse owned by Wildberries, Russia's largest online retailer, in ​the city of Kotovsk in the Tambov region, roughly ⁠475 kilometres (295 miles) southeast of Moscow.

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

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

Ukrainian President Volodymyr Zelenskiy 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, Zelenskiy wrote on X.

The governor of the Moscow region, Andrei Vorobyov, said 24 people were injured following a drone attack on another Wildberries warehouse in Elektrostal, ​a city east ​of Moscow.

Wildberries ⁠co-founder and CEO, Tatyana Kim, said it had been a "terrible night" for Russia and for the ​company, offering her condolences to the victims' families.

In ​the ⁠city of Noginsk, also in the Moscow region, falling drone debris caused a fire to break out at an oil depot, Vorobyov ⁠said.

He ​did not specify the damage to the ​facility, but said two people were injured in Noginsk and a nearby maternity ​hospital had been evacuated.
