Ukrainian drones have hit several warehouses of Russia's largest online retailer Wildberries in a matter of days, dealing a blow to a large number of small and medium-sized businesses. This was reported by Qazaqyia.kz citing BBC News.

After months of drone attacks on oil depots and refineries, Kyiv says it is now targeting logistics hubs used by Russians to buy military equipment, and disrupting supplies to the Russian army. But it has also frustrated hundreds of Russian sellers who depend on online marketplaces for their livelihoods, making the war feel closer to home after almost four and a half years.

"I am a mother of a disabled child, I've built the business myself," one woman complained on an expletive-laden social media post that went viral. "I've lost 1m roubles (£9,500; $12,700)... We're already getting screwed over from every direction as it is."

In Ukraine's first attack on Wildberries at the weekend, two warehouses were hit, at Elektrostal east of Moscow and in Kotovsk in the Tambov region, some 400km (250 miles) from the Ukrainian border. Seven workers on a nightshift were killed in Kotovsk and one was fatally wounded at Elektrostal. Dozens more were injured and goods worth an estimated at £750m ($1bn) were destroyed.

Kyiv said it had struck "major logistics facilities" used to "supply sanctioned components for drone production and navigation equipment". Further attacks overnight into Wednesday hit Wildberries logistic hubs at Krasnodar and Nevinnomyssk in the Stavropol region. The company's owner Tatiana Kim said further casualties had been reported.

"We are, quite justly, bringing the war back home - to Russia," said Ukraine's President Volodymyr Zelensky. Russia has targeted Ukrainian cities with drones and missiles since the start of the full-scale invasion in February 2022 and recent Russian attacks have hit Ukrainian warehouses and cargo terminals.

Sorting terminals for Ukraine's largest private postal operator, Nova Poshta, have come under attack, so too have warehouses owned by retail chain ATB and confectionery group Roshen. With the situation on the front line now close to a stalemate, Ukraine's long-distance drone campaign has hit supply routes and energy facilities, in effect cutting off annexed Crimea and leading to fuel shortages across Russia.

Businesses had already been disrupted before the warehouse attacks, but now some have lost much of their stock overnight. Wildberries and its rival Ozon are used by 85-90% of Russia's economically active population, it is estimated. In many remote places lacking accessible stores, Russians depend on them for much of their shopping, from clothes to household appliances.

The Kremlin has denied that online platforms are used for army supplies, but a variety of military-related goods such as body armour are on sale, alongside items with both civilian and drone-production applications. Pro-war bloggers say the platforms are routinely relied on by volunteers to buy kit that is then sent to the front. There is, however, no independent confirmation that the warehouses targeted in the attacks stored these supplies.

Unlike Western retail giant Amazon, which sells goods directly alongside its marketplace business, Wildberries and Ozon act almost entirely as marketplaces, connecting independent sellers with buyers across Russia, storing and delivering their goods and handling payments. This means many of the losses incurred in the attacks have been borne by businesses.

For one woman, who sells stationery items, Wildberries is the only distribution channel. The day after she delivered her goods to the Elektrostal warehouse near Moscow last Friday, she learned that it had all gone up in flames. She still has other inventory left, but this time of the year is important for her business, as parents and students stock up for the new autumn term.

Another Wildberries trader who sells teenage clothing, told the BBC she had lost about 1.4m roubles (£13,300) worth of stock. She is halting new supplies for a few weeks. "The outlook for working with Wildberries is very murky," she said. "Right now I have enough of a safety cushion to survive the current losses, but if there are more strikes, I probably won't manage."
