Iran's Assembly of Experts, tasked with selecting the country's new supreme leader, has reached a decision, according to a member, although the name has yet to be announced.

Ahmad Alamolhoda, a prominent Iranian cleric and a member of the Assembly of Experts, said the vote on Iran's next leader has already taken place and a new leader has been selected.

He said reports suggesting the Assembly of Experts had not yet reached a decision were "completely false," adding that under the constitution, no one – including members of the Assembly – has the right to change that decision.

Alamolhoda said the matter now rests with Ayatollah Hosseini Bushehri, the official responsible for the Assembly's secretariat, who he said is tasked with conveying and publicly announcing the body's decision.

US President Donald Trump said earlier that he must be personally involved in selecting Iran's next leader, the US news website Axios reported Thursday.

On February 28, Israel and the United States launched joint attacks on Tehran and several other Iranian cities, killing Khamenei, as well as many others, including some of the leader's family members, high-ranking military commanders and civilians.
