Iranian rescue services have found the wreckage of President Ebrahim Raisi’s helicopter in a mountainous area in the country’s north-west, state media said, though they have not have provided any details about his condition.

A helicopter carrying Raisi crashed on Sunday, according to Iranian officials. Tasnim News Agency, which is closely linked to the elite Revolutionary Guards, reported that rescue teams spotted the rotor blades of the helicopter on a hill this morning after the weather cleared up following a freezing night, during which thick fog and snow had hindered rescue efforts.

State media had earlier shown video footage of a convoy of ambulances struggling to make their way through thick fog up a mountain road. The crash site has been located in Arasbaran Forest near the border with Azerbaijan, according to Tasnim.
