Iran’s supreme leader has appointed First Vice President Mohammad Mokhber as the country’s acting president after a helicopter crash killed President Ebrahim Raisi.

Ali Khamenei made the announcement in a condolence message he shared for Raisi’s death in the crash Sunday. The helicopter was found Monday in northwestern Iran.

Khamenei also announced five days of mourning in the message.

Mokhber now has a maximum period of 50 days to hold elections, Iran's official news agency IRNA reported.

Iran's government cabinet also appointed on Monday Deputy Foreign Minister Ali Bagheri Kani as acting foreign minister following the death of Hossein Amirabdollahian in the same helicopter crash.
