Tehran hit by oil-strike pollution, sparking 'black rain' and health concerns
Air strikes on Tehran's oil facilities have produced dense smoke plumes and an unprecedented mix of pollutants, with reports of 'black rain' as fires burn at the Tehran refinery and Shahran depot; the WHO warns such attacks risk harming air, water and food, and scientists say the pollutant mix is unusually dangerous, potentially causing immediate and long-term health risks even as forecasts of rain and wind may help disperse contaminants.
