No survivors were found at the crash site of the helicopter carrying Iran's President Ebrahim Rais, 63, and the foreign minister, Iran's state-run IRINN news agency and the semi-official Mehr News agency reported.
President Ebrahim Raisi, Foreign Minister Hossein Amir-Abdollahian and several others are confirmed to have been killed in Sunday's helicopter crash in northwest Iran.
Drone footage has been shared on the social media channels of Iran's state news agency IRNA, which the agency says shows the wreckage of President Raisi's helicopter.
The footage, shot by the Red Crescent, appears to show the tail of a helicopter next to a scorched earth on a hillside littered with debris.
Rescue teams said there were no signs of life at the site.
Reuters also reported that the helicopter was "completely burnt" in the crash, citing an Iranian official.
"President Raisi's helicopter was completely burnt in the crash...unfortunately, all passengers are presumed dead," the official said.
