Search and rescue teams are continuing to search for an Iranian plane that crashed in bad weather on Sunday.
Officials told state media that the wreckage had been found, but an aviation spokesman said he could not confirm this.
The Aseman Airlines passenger plane came down in the Zagros mountains on Sunday, and all 66 people on board are feared to have been killed.
Hundreds of mountaineers with dogs and drones are trying to reach the site.
The searchers face bad weather conditions. Due to fog and strong winds, helicopters that were deployed for the search at dawn on Monday have had to be grounded, a Red Crescent official told local media.
And on Sunday, teams had to stop work altogether due to winds and snow.
Flight EP3704 left Tehran at 04:30 GMT on Sunday, and crashed about an hour later in the Mount Dena area, about 22km (14 miles) from its destination.

On Monday officials from the region told news channels rescuers had reached the site.
But both channels – IRINN and English-language Press TV – said they could not confirm the reports independently, and a civil aviation spokesman told Reuters news agency the reports could not be confirmed.
