A helicopter carrying Iranian President Ebrahim Raisi, Foreign Minister Hossein Amirabdollahian, and other officials crashed on Sunday, causing regional shock waves. They were returning from a trip to Iran’s border with Azerbaijan. The crash occurred in Dizmar forest in East Azerbaijan province due to bad weather and fog. Search operations are hindered by the terrain and poor visibility. If Raisi died, First Vice President Mohammad Mokhber would assume the presidency. International reactions include offers of assistance from Russia, Iraq, Qatar, and Azerbaijan.
