Following Ukrainian drone attacks targeting oil refineries in Russia, Moscow residents are reporting an oily residue falling in several districts. Reports and images circulating online depict a noticeable film on cars and surfaces, prompting complaints from citizens. Russian authorities have not yet officially confirmed the source of the substance, but the timing coincides with the drone strikes. The affected areas include those southwest and east of the city center. This incident marks a rare instance of direct consequences from the conflict being felt within Moscow itself. Ukrainian officials have not directly claimed responsibility for the “oil rain,” but have acknowledged targeting Russian energy infrastructure.
