According to Russian authorities, seven people were killed and 25 injured in an attack on a Wildberries warehouse in the city of Tambov, around 475 kilometres southeast of Moscow. Another person was killed and 37 others were injured when a second warehouse was hit in Elektrostal, in the Moscow region.
Ukrainian President Volodymyr Zelensky confirmed the operation, saying the strikes targeted "major logistics facilities" that had been used to supply sanctioned components for drone production and navigation equipment.
He added that Ukrainian forces also struck targets in the Sea of Azov, the Black Sea and Russian-annexed Crimea.
Videos circulating online showed massive fires engulfing one of the logistics centres, with thick black smoke rising into the sky as dozens of workers fled the premises.
Some footage appeared to show injured employees escaping while explosions continued, while another clip showed parts of the warehouse collapsing as flames spread through the building.
Zelensky said the operation was carried out in response to continued Russian attacks on Ukrainian civilian infrastructure and population centres. According to Ukrainian authorities, 14 people were killed in Russian strikes across Ukraine overnight into Wednesday.
Wildberries, often described as Russia s equivalent of Amazon, merged with advertising company Russ to form the RWB Group, which Forbes Russia valued at approximately $12.6 billion in 2026.
Serhii Kuzan, chairman of the Ukrainian Security and Cooperation Centre, told the BBC that Wildberries plays a significant role in Russia s logistics network and has been used by volunteers to purchase military equipment, including radios, body armour and drone components.
He said Ukraine s objective was to disrupt the flow of dual-use goods, critical electronics and sanctioned components to the Russian military and defence industry.
Kuzan added that the strikes could also have wider economic and psychological effects inside Russia.
Russia has similarly targeted logistics centres, postal facilities and electronics distributors in Ukraine since launching its full-scale invasion in February 2022.
Wildberries Chief Executive Officer Tatyana Kim described the incident as "a terrible night" for both Russia and the company.
Tambov Governor Evgeniy Pervyshov said seven employees working the night shift were killed instantly. He added that Russian air defences intercepted 28 drones approaching the region.
According to the governor, 25 people were injured, including seven who remain in serious condition, with most suffering shrapnel wounds.
He described it as the largest and deadliest drone attack the region had experienced in terms of both the number of drones involved and the resulting casualties.
Meanwhile, Moscow Region Governor Andrei Vorobyov said eight of those injured in the Elektrostal attack were in critical condition.
He said Russian air defences shot down 48 drones across the region overnight and confirmed that a falling drone also struck an oil depot, causing what he described as the night s most serious material damage.
Firefighters and emergency responders remain at the affected sites.
Zelensky separately confirmed that Ukrainian forces had also targeted an oil facility.
Ukraine has intensified long-range drone attacks on Russian energy infrastructure in recent months, aiming to weaken Moscow s ability to finance its war through oil and gas exports.
Earlier this month, Kyiv claimed that nearly 43 per cent of Russia s oil refining capacity had been disabled, although that figure has not been independently verified.
Russian President Vladimir Putin acknowledged in June that Ukrainian strikes had contributed to fuel shortages and subsequently signed legislation intended to increase fuel supplies to Russia s domestic market.
