Iranian sources said that a chopper carrying Iranian President Ebrahim Raisi crashed on Sunday in northern Iran. Rescuers are looking for the wreckage in the dark. As the temperature drops in the hilly region overnight, Raisi's health and that of Iranian Foreign Minister Hossein Amir Abdollahian, who was also on board, are still unknown.

State media said that dozens of rescue teams and military drones participated in the enormous search and rescue operation after the aircraft went down in Iran's East Azerbaijan region early in the afternoon.
