Tehran Governor Hossein Hashemi has announced Tehran has only had four days of clean air since last March.

IRNA reported on Monday February 24 that the governor was speaking at the first meeting of the administrative council of Tehran Province, saying air pollution is by far the most important problem facing the capital and its residents.

According to the governor’s report, hundreds of thousands of worn-out cars are being driven in Tehran, exacerbating the air-quality woes.

The governor announced that President Hassan Rohani has established a committee to address the chief problems facing Tehran ,with air pollution and water and power shortages at top of their list.
