Tehran, Dec 19, IRNA - Air pollution has forced Iranian authorities to close kindergartens and all other schools in Tehran province for two days from Sunday.

Decision for the school closure for two days was made by a crisis committee on air pollution.

Tehran has been suffering from dangerous levels of pollution and smog since the beginning of the month.

In the mornings, the sun has been barely visible owing to the city's smog.

State radio and television broadcast hourly warnings urging residents either to stay indoors or to use public transport instead of driving their cars.
