BEIRUT: The apparent crash of a helicopter carrying Iran's president and foreign minister on Sunday sent shock waves around the region.

Details remained scant in the hours after the incident, and it was unclear if Iranian President Ebrahim Raisi and the other officials had survived.

Here's what we know so far.

• WHO WAS ON BOARD THE HELICOPTER AND WHERE WERE THEY GOING? The helicopter was carrying Iranian President Ebrahim Raisi, the country’s Foreign Minister Hossein Amirabdollahian, the governor of Iran’s East Azerbaijan province and other officials and bodyguards, according to the state-run IRNA news agency. Raisi was returning from a trip to Iran’s border with Azerbaijan earlier Sunday to inaugurate a dam with Azerbaijan’s President Ilham Aliyev, the news agency said.

• WHERE AND HOW DID THE HELICOPTER GO DOWN? The helicopter apparently crashed or made an emergency landing in the Dizmar forest between the cities of Varzaqan and Jolfa in Iran's East Azerbaijan province, near its border with Azerbaijan. Initially, Interior Minister Ahmad Vahidi said the helicopter "was forced to make a hard landing due to the bad weather and fog.”
