IRNA, quoting local aviation officials, said a technical issue delayed the plane’s landing, which caused the accident.

Iranian media reported that the pilot was unable to deploy the landing gear, adding that the incident was being investigated.

“The plane did not catch fire and all passengers safely left the plane,’’ Managing Director of Khuzestan Airports, Mohammad Reza Rezaei, told IRNA.

On Saturday, an Iranian aeroplane en-route from Tehran to Istanbul made an emergency landing at a Tehran airport because of a technical problem.
