The pollution levels in Iran’s capital Tehran have got so bad that schools have had to shut down. Officials statements have also been released to apologise to tourists for the high levels of air pollution.
On Sunday, Tehran was struck by a cloud of smog, affecting its 14 million residents. According to the Air Quality Index, the pollution in the city hit the high mark of 156 – a dangerous number, considering that an Index of 150 is already considered unhealthy. Many had to flee indoors or wear a face mask to avoid the toxic fumes.
