Over the last two months, Ukrainian drones have struck sites belonging to Wildberries, which as Russia’s Amazon, delivers clothing, electronics, groceries and household goods to millions of Russians.

A drone full of explosives was discovered on August 4 near a Ukrainian cargo plane on the grounds of Leipzig/Halle airport, about 170km south of Berlin. Authorities have also investigated a suspicious mid-air collision with a postal plane that had happened on the same night.
