A helicopter carrying Iranian President Ebrahim Raisi suffered a “hard landing” in “adverse weather conditions” Sunday, according to state-run media, which said Iranian Foreign Minister Hossein Amir-Abdollahian and other officials were also on board. Their condition is not yet known.

“We have been in communication with the president’s companions, but due to the complexity of the area, communication is somewhat challenging,” Interior Minister Ahmad Vahidi said in a statement carried on state television. “We are awaiting the arrival of rescue teams at the scene of the incident and the helicopter’s landing site to provide us with information.”
