Iranian President Ebrahim Raisi, the country’s foreign minister and others have been found dead at the site of a helicopter crash after an hourslong search through a foggy, mountainous region of the country’s northwest, state media reported, writes ABC NEWS.

State TV gave no immediate cause for the crash in Iran’s East Azerbaijan province. With Raisi were Iran’s Foreign Minister Hossein Amirabdollahian, the governor of Iran’s East Azerbaijan province and other officials and bodyguards, the state-run IRNA news agency reported.

Turkish authorities early Monday released what they described as drone footage showing what appeared to be a fire in the wilderness that they “suspected to be wreckage of a helicopter.” The coordinates listed in the footage put the fire some 20 km south of the Azerbaijan-Iranian border on the side of a steep mountain.

Footage released by the IRNA early Monday showed what the agency described as the crash site, across a steep valley in a green mountain range. Soldiers speaking in the local Azeri language said: “There it is, we found it.” Shortly after, state TV in an on-screen scrolling text said: “There is no sign of life from people on board”.
