Iran's President Ebrahim Raisi was inaugurating a joint dam project with Azerbaijan on the shared border hours before his helicopter made a rough landing in heavy fog on the return journey on Sunday (May 19).
The helicopter carrying Raisi and his foreign minister crashed as it was crossing mountain terrain in
heavy fog on the way back from a visit to the border with Azerbaijan, an Iranian official told Reuters.
The official said the lives of Raisi and Foreign Minister Hossein Amirabdollahian were "at risk following the helicopter crash". The bad weather was complicating rescue efforts, the state news agency IRNA reported.
