Hundreds have been killed by government forces in Iran after mass protests over a sudden spike in fuel prices, which marks the deadliest political unrest in the area since the revolution in 1979.TEHRAN, Iran -- Dangerously poor air quality forced Iran’s government on Monday to extend school closures in the capital Tehran, a city home to over 10 million people.
Nearby mountains were completely obscured by the a thick layer of air pollution called an inversion that's been hovering over the capital since last month. Tehran’s air is among the most polluted in the world. Similar school closures were in effect in other cities as well. Still, despite the pollution, many students seemed to be enjoying their extended vacation, according to one schoolteacher in Tehran, Maryam Lavasani.
"Breathing is really difficult for me. What can I do? If I don't leave home, how can I take care of my daily jobs? And when I come out of the house, the air pollution really hurts me,” she said.He blamed the smog on older, deficient cars and problems with the fuel they burn, saying air pollution is present in smaller cities and towns as well.
