Residents across southeastern Moscow woke on Thursday, 18 June 2026, to smoke-filled skies and reports of black soot settling on cars, balconies and windows after a Ukrainian drone strike hit the Moscow Oil Refinery. Dark residue could be seen spread across residential neighbourhoods from online videos, with some residents describing the fallout as 'black rain'.
The facility, located in the Kapotnya district around 15 kilometres from the Kremlin, was among the targets during what Russian officials described as thelargest drone attack on the capital since the start of the full-scale war. Moscow Mayor Sergei Sobyanin said Russian air defences intercepted at least 194 drones heading towards the city overnight. Russia's Ministry of Defence said nearly 1,000 drones were shot down across the country as part of a wider attack that stretched across several regions.
Authorities reported at least 17 people were injured, while flights were temporarily suspended at Moscow's major airports. While Kyiv has not publicly detailed all aspects of the operation, much of the attention quickly focused on the refinery fire and the layer of soot reportedly left behind across parts of the city.
Attention quickly turned to the environmental impact of the blaze after images emerged showing black residue covering vehicles, window ledges and residential buildings near the refinery.
Residents in Maryino, which borders Kapotnya, described hearing multiple explosions during the early hours of the morning before seeing thick smoke rising above the facility. Several reported a strong smell of burning fuel lingering for hours after the attack.
While some social media users described the fallout as 'black rain', Russian officials disputed suggestions that oil had fallen from the sky. Authorities said the material was soot generated by the refinery fire, although they acknowledged that smoke and particulate matter had spread across nearby districts.
Local authorities advised residents in affected areas to keep windows closed and limit time outdoors because of air quality concerns.
