Iranian authorities have been forced to shut down all nurseries and elementary schools in Tehran after air pollution reached alarming levels, Tasnim news reported on Sunday.
Members of Tehran’s Air Pollution Emergency Committee held a meeting on Saturday night and decided to shut kindergartens and primary schools in all but two cities of Tehran governorate on Sunday.
Schools in the cities of Firoozkooh and Damavand, located in the northeast of the capital city, will continue their routine activities.
The decision came as the average level of PM2.5 particles in the governorate's air hit 150.
The committee added that further decisions will be made on whether to close schools on Monday if the pollution continues in next days.
