Riyadh, March 10, 2026 (Saudi Arabia Breaking News) — World Health Organization warned Tuesday that “black rain” and toxic air pollution reported in parts of Iran following strikes on oil facilities could pose health risks and trigger respiratory problems.
The WHO, which maintains an office in Iran, said it had received multiple reports this week of rainfall contaminated with oil particles.
Large plumes of black smoke were seen over Tehran on Monday after an oil refinery was hit during an escalation of strikes targeting Iran’s domestic energy infrastructure.
“The black rain and the acidic rain coming with it is indeed a danger for the population, respiratory mainly,” WHO spokesperson Christian Lindmeier said during a briefing in Geneva.
He said the strikes had caused “a massive release of toxic hydrocarbons, sulfur oxides and nitrogen compounds into the air.”
Scientists warned that exposure to contaminated smoke or airborne particles could cause headaches, skin and eye irritation and breathing difficulties. Prolonged exposure could also increase long-term health risks, including cancer.
The warning came as Iranian authorities urged residents to remain indoors amid deteriorating air quality in affected areas.
