Iran’s first Vice President Mohammad Mokhber has been appointed as acting President following the death of President Ebrahim Raisi in a helicopter crash in the East Azerbaijan province.

Iranian Supreme Leader Ayatollah Ali Khamenei announced the appointment of Mokhber in a condolence message he shared for Raisi’s death in the crash on Monday.

Raisi was earlier confirmed dead in a helicopter crash in mountainous terrain near the Azerbaijan border.

The charred wreckage of the helicopter which crashed on Sunday carrying Raisi and Foreign Minister Hossein Amirabdollahian was found in the early hours of Monday after an overnight search in blizzard conditions.

“President Raisi, the foreign minister and all the passengers in the helicopter were killed in the crash,” a senior Iranian official told Reuters, asking not to be named because of the sensitivity of the matter.

Pictures from the site showed the aircraft slammed into a mountain peak, although there was no official word on the cause of the crash.

State news agency IRNA said Raisi, a hardliner long seen as a potential successor to Supreme Leader Ayatollah Ali Khamenei, was flying in a U.S.-made Bell 212 helicopter.

Raisi, 63, was elected president in 2021, and since taking office has ordered a tightening of morality laws, overseen a bloody crackdown on anti-government protests and pushed hard in nuclear talks with world powers.

Khamenei, who holds ultimate power with a final say on foreign policy and Iran’s nuclear programme, had earlier sought to reassure Iranians, saying there would be no disruption to state affairs.

The crash comes at a time of growing dissent within Iran over an array of political, social and economic crises. Iran’s clerical rulers face international pressure over Tehran’s disputed nuclear programme and its deepening military ties with Russia during the war in Ukraine.

Since Iran’s ally Hamas attacked Israel on October 7, provoking Israel’s assault on Gaza, conflagrations involving Iran-aligned groups have erupted throughout the Middle East.
