The Iranian capital is once again suffering from poor air quality and countermeasures such as the closure of schools do not seem to have helped much in alleviating the problem.
Despite the closure of kindergartens and elementary schools on Saturday, air pollution stubbornly remained at an alarming level in Tehran. This is while schools and administrative offices are also closed in Iran on Fridays.
The capital's Air Quality Index (AQI) was reported at 154 and declared as “unhealthy” for people of all ages and health conditions.
The megacity of Tehran, with an estimated population of 14 million people, is currently shrouded in a thick grey blanket of smog and suffering low visibility.
Pollution levels like the ones recorded in India and China, heavy congestion and cold weather normally cause brown-white smog in Tehran in autumn and winter days each year.
Many blame the quality of gasoline and substandard cars for the poor air quality in the sprawling city.
