Former president Mahmoud Ahmadinejad was seen at the procession, local media reported. It appeared to be his first major public appearance since the start of the war, when three of his bodyguards were reportedly killed in a strike near his home.

Iran's current president, Masoud Pezeshkian, was also filmed walking among a group of mourners on a Tehran street.

Earlier, he wrote on X that Khamenei had taught everyone in Iran that the country's "greatest asset" was "its people and their unity". He promised that Iranians would "continue the path of Iran's honour, progress, and glory".

Israeli Defence Minister Israel Katz said Khamenei was "eliminated by Israel" because he had threatened its existence. "Any Iranian leader who will again try to pursue plans to destroy Israel will be killed as well," he added.
