I don't like following links to other places, so here's the text from reddit:

"There are about 10 million people living in the densely urban areas of Tehran and about 15 million total counting those residing in its immediate surroundings and suburbs.

It takes just one drop of oil to contaminate 200 liters/50 gallons of water. There are videos of soot and crude literally raining from the sky - houses and streets coated in oil, trees spontaneously catching fire.

Cancer rates will skyrocket, including birth defects from the massive volumes of volatile hydrocarbons released in the atmosphere. Every aquifer and underground water supply will be poisoned for the foreseeable future. Fauna - from household pets to birds and insects - will be eradicated, plants will wither and die and every crop growing there, if any survive, will end up contaminated by the soil. Tehran has, for all intents and purposes, been set on an irreversible course toward becoming a wasteland.

US and Israel essentially dropped the equivalent of a dirty bomb on Iran - just without the explosion or immediate effects. The fact that the news is reporting on this without commenting on its unthinkable consequences for the region is simply surreal.

This is arguably the biggest war crime committed by a sovereign nation since World War 2. If Western countries still had an ounce of moral backbone, they would be turning the US and Israel into pariah states at best or labeling them rogue nations after today's act."
