Who Caused the Polution in Iran?

"Iranians blame high pollution on sanctions"

Iran has suffered from an unussually high amount of pollution for the past four weeks. Some blame the ridiculous weather, while others complain that U.S. sanctions are the main cause. The U.S. has denied gasoline imports to Iran and thus they have resorted to petrochemical plants into oil refineries. The Iranian gasoline is much more polluted and hazardous than the imported gasoline was. Hospitals have seen an increase in respitory and heart problems. Some students have stopped going to school.
