The semi-official Tasnim news agency quoted a report by the General Staff of Iran's Armed Forces stating that a senior investigation committee, comprising experts and technicians, arrived at the crash site on Monday morning following the incident.
According to Article 131 of Iran's Constitution, the first Vice-President will take the helm of the executive branch if the President is unable to perform duties.
Mehr news agency reported today that the Iranian president, foreign minister, and other occupants of the helicopter, including East Azerbaijan Province Governor Malek Rahmati, have been declared "martyred".
Rescuers found the wreckage of a helicopter carrying Iran's President Ebrahim Raisi and other officials in northwest Iran, with no signs of life detected. The crash follows Iran's recent drone-and-missile attack on Israel and ongoing mass protests.
