Search and rescue teams have arrived at the location where a heat source was identified in the mountainous region of Iran's East Azerbaijan province, but have not yet located the crash site of the helicopter carrying Iranian President Ebrahim Raisi, Iran's semi-official FARS news agency reported.
Authorities had believed the site of the heat source could be related to where the helicopter carrying nine people including President Raisi and the country's foreign minister crashed.
Search efforts continued throughout the night and into daylight on Monday to locate the site of the crash under difficult weather conditions with dense fog and extreme cold.
