WHO warns of health risks from ‘black rain’ in Iran

The World Health Organization warns that the “black rain” falling in Iran after strikes on oil facilities could cause respiratory problems, and it backs Iran’s advisory urging people to remain indoors.
The UN health agency, which has an office in Iran and works with authorities on health emergencies, says it has received multiple reports of oil-laden rain this week. Tehran was choked in black smoke on Monday after an oil refinery was hit, in an escalation in strikes on Iran’s domestic energy supplies as part of the US-Israeli campaign.
“The black rain and the acidic rain coming with it is indeed a danger for the population, respiratory mainly,” WHO spokesperson Christian Lindmeier tells a press briefing in Geneva, adding that Iran had advised people to stay indoors.
Asked whether the WHO backed that advice, he says: “Given what is at risk right now, the oil storage facilities, the refineries that have been struck, triggering fires, bringing serious air quality concerns, that is definitely a good idea.”
One video sent to Reuters by a WHO staff member shows what they said was a cleaner mopping up black liquid at its office entrance in Tehran on March 8. Reuters is not able to independently verify the footage.
