Residents in parts of south-east Moscow reported a light drizzle that left black marks on clothing and other surfaces after a refinery was struck during a major Ukrainian drone attack. While city authorities denied reports of "oil rain", Moscow's official Telegram channel advised people in the affected district to keep their windows closed and urged families with children, elderly residents and those with asthma to leave the area.
The reports emerged after Ukraine launched its largest drone attack on Russia since the start of the full-scale war, targeting Moscow and other regions with nearly 200 drones aimed at the Russian capital. The assault damaged a refinery in south-east Moscow, sparked fires and left 17 people injured in the Moscow region, according to regional governor Andrei Vorobyov.
