TEHRAN: Britain and Canada advised travellers late on Friday not to use Iran’s main new international airport because of concern over its safety, just hours before the airport was due to receive its first flights. “We are aware of reports that the runway at the new Imam Khomeini International Airport in Tehran may not yet be suitable for use,” the British Foreign Office said of the airport, due to open on Saturday. “We are in contact with the Iranian authorities about this. Until the situation has been clarified, we advise British travellers to travel by flights using the existing (Mehrabad) airport.” The Canadian government issued a virtually identical warning. It was not immediately clear whether any other countries were giving the same advice. Iran said the runway had been approved by international experts. reuters
