Iran’s Civil Aviation Organisation has announced temporary restrictions over the western part of the country’s airspace.
The move was announced amid heightened tensions over reports that the US is considering renewed military action against Iran while diplomatic efforts continue.
According to the latest NOTAM notification, strict restrictions apply to all passenger flights over western Iran.
Only eight airports in Iran are now allowed to operate, including Mehrabad and Imam Khomeini airports in Tehran, and Isfahan and Yazd airports in central Iran.
At these operational airports, flights are restricted to daylight hours (sunrise to sunset) and airlines must obtain a new permit from the Civil Aviation Organisation for each individual flight.
