The operation started shortly after the tragic incident on Sunday noon, but it was stopped in the night and resumed as of Monday morning.
Bad weather, including dense fog, snow, and wind, as well as the remote location of the crash site and rugged terrain are hampering the recovery efforts in the Dena mountain range.
Rescue helicopters have been unable to land in the area due to fog and high winds.
Search and rescue teams, both on foot, in cars, and on helicopters have been looking for the debris, but to no avail. A drone has also been used to spot the plane. However, the weather is reportedly getting better, raising the chance of finding the wreckage.
The ATR-72 flight operated by the Aseman Airlines crashed on Sunday morning 50 minutes after taking off from Tehran’s Mehrabad Airport, and did not make it to Yasuj, a mountainous city in western Iran.
The Aseman Airlines’ spokesperson said all the 59 passengers and 6 crew members have been killed.
