Looking in detail: Helicopter crash that killed Iran's president

BEIRUT: The helicopter crash that killed Iran's president and foreign minister has sent shock waves around the region.

Iranian state media said on Monday that President Ebrahim Raisi, Foreign Minister Hossein Amirabdollahian, and others have been found dead at the site after an hours-long search through a foggy, mountainous region located in the northwest side of the country.

Here's what we know so far.

WHO WAS ON BOARD THE HELICOPTER AND WHERE WERE THEY GOING?

Raisi, Amirabdollahian, the governor of Iran's East Azerbaijan province and other officials and bodyguards, were on the helicoptor according to the state-run IRNA news agency.

Raisi was returning on Sunday after travelling to Iran's border to inaugurate a dam with Azerbaijan's President Ilham Aliyev when the crash happened in the Dizmar forest in Iran's East Azerbaijan province, under unclear circumstances.

HOW DID THE SEARCH OPERATION GO?

Iranian officials have said the forested terrain and heavy fog impeded search-and-rescue operations, which began on Sunday. The Iranian Red Crescent Society president, Pir-Hossein Koulivand, said 40 search teams were on the ground despite “challenging weather conditions.”

"Because of the bad weather, it was impossible to conduct aerial searches via drones," Koulivand said, according to IRNA.

HOW WAS THE CRASH SITE FOUND?

Early on Monday, Turkish authorities released what they described as drone footage showing what appeared to be a fire in the wilderness that they “suspected to be the wreckage of a helicopter.”

The coordinates listed in the footage placed the fire around 20 kilometres south of the Azerbaijan-Iranian border on the side of a steep mountain.

Footage released by IRNA showed what the agency described as the crash site, across a steep valley in a green mountain range.

Soldiers speaking in Azeri language said: “There it is, we found it.” Shortly after, state TV through an on-screen scrolling text said: “There is no sign of life from people on board.”

HOW WILL RAISI'S DEATH IMPACT IRAN?

Raisi was seen as a protégé to Iran's supreme leader Ayatollah Ali Khamenei and a potential successor for his position within the country's Shiite theocracy.

Under the Iranian constitution, if a president dies, the country's first vice president — in this case, Mohammad Mokhber — would become president. Khamenei has publicly assured Iranians that there would be “no disruption to the operations of the country” as a result of the crash.

WHAT HAS THE INTERNATIONAL REACTION BEEN?

After the news first broke of the search operation, countries including Russia, Iraq and Qatar made formal statements of concern about Raisi's fate and offered to assist in the search.

Azerbaijani President Aliyev offered to provide the necessary support. Relations between the two countries have been chilly due to Azerbaijan's diplomatic relations with Israel, Iran's regional arch-enemy.

Saudi Arabia, traditionally a rival of Iran although the two countries have recently made a rapprochement, said it stands by "Iran in these difficult circumstances.”

There was no immediate official reaction from Israel.

Last month, following an Israeli strike on an Iranian consular building in Damascus that killed two Iranian generals, Tehran launched hundreds of missiles and drones at Israel.

They were mostly shot down and tensions have reportedly since subsided.
