Tehran, Jan 2, IRNA � An Iranian official said on Saturday that Tehran's air quality index showed a healthy state after three weeks.

Talking to IRNA, Deputy Head of Iran's Environmental Protection Organization for Monitoring and Supervision, Mohammad Rastegari, said the Iranian capital's air quality is healthy today after three weeks of severe air pollution.

Polluted and unhealthy air quality forced the country's officials to close all schools and kindergartens in the capital last week.

Last week, Iranian Cabinet made a decision to devise short-term and swift plans for controlling air pollution.

The cabinet session mandated all organs concerned to seriously implement related plans.

'Public concerns over air pollution, especially in the metropolitan cities, are right and efforts should be made to alley their concerns.

Though air pollution has existed for many years and it cannot be fully eliminated in the short term, government considers it necessary to take short- and mid-term plans to control air pollution, which has become more tangible for the public these days. People should feel all problems are being tackled and solved,' President Hassan Rouhani said.
