The level of pollution in Tehran has reached a dangerous level. Witnesses describe it as shocking (jrezaian/WashPost/Twitter). The local radio is asking the Tehranis to stay home, saying going outside in the current conditions is suicide. All government buildings and schools are closed. The poor quality of domestically produced gasoline is said to be the major culprit.
