Iranian media on Sunday, 24 Aban, published images of air pollution in Tehran.

Based on data from the international air quality monitoring website IQAir, Tehran recorded an air pollution index of 193, placing it second among the most polluted large cities in the world and in the “unhealthy” range.

Air pollution is one of Iran’s longstanding environmental and health crises, affecting the health of millions of citizens every year.

Scott Bessent, the U.S. Treasury secretary, recently said about the deep crises facing the Iranian people that the reason for this situation is that the government has spent the country’s resources on violence and terrorism outside its borders rather than providing for people’s welfare within the country.
