Ukrainian drones struck three warehouses across Russia overnight, including two run by online retailer Wildberries, killing five people, local officials said yesterday.

Wildberries said its warehouse near St Petersburg had caught fire but that there were no casualties. In the Tver region, to the northwest of Moscow, another Wildberries facility was damaged by drones, Vitaly Korolyov, the acting regional governor said. Nobody was hurt in that attack.

But in the Moscow region, home to 22 million people, a drone attack on the city of Chekhov set an unnamed warehouse alight and killed five people, the governor, Andrei Vorobyov, said. A further 10 people were injured.

Kyiv has sought to disrupt the operations of Wildberries, which is often described as Russia’s answer to Amazon and is a linchpin of the consumer economy.

Russian forces struck seven cargo vessels in the Ukrainian port of Mykolaiv and in the Black Sea, the RIA state news agency said yesterday, citing the defence ministry.

Turkish officials said a drone attack on two civilian vessels in the Black Sea had left crew members injured. The foreign ministry said the ships were attacked after leaving the Russian port of Novorossiysk late on Monday and several personnel were wounded, adding that “their situation is being closely monitored”.
