Ukrainian drones hit a warehouse for a Russian e-commerce giant near Saint Petersburg early Friday, triggering a fire that sent smoke pouring over the historic city, according to local officials and an AFP reporter.

Kyiv has targeted Saint Petersburg as it steps up long-range drone strikes on Russian energy, military and logistics sites in recent weeks.

An AFP reporter saw grey smoke rising into the morning sky over high-rise buildings in the city, which is more than 800 kilometres (500 miles) from the Ukrainian border.

The local governor reported that a warehouse for Wildberries — Russia’s largest online retailer often referred to as “Russia’s Amazon” — was on fire after the strike.

“Three people were wounded,” Alexander Drozdenko, governor of the surrounding Leningrad region said on social media.
