Khamenei Rahbar!

The Islamic Republic's religious and political leaders have called on Iranians to pledge allegiance to the new supreme leader who is close to Iran's hardline revolutionary guards.

President Trump previously said that Mojtaba Khamenei would be unacceptable as Iran's leader, and Israel has said it will target any successor.

The choice appears to signal that there will be no change in Iran's determination to resist US and Israeli attacks.

Danny Danon, Israeli ambassador to the United Nations, gave his reaction.

It really doesn't matter if it is the father or the son.

You have to look at the policy.

And the policy of this regime is the same policy, to promote terror, to sow chaos, to acquire nuclear capabilities so they can actually assemble it on the ballistic missiles.

Anyone who is involved

with this terror regime is a legitimate target and will continue to target the IRGC and all of those who are collaborating with this regime.

Shortly after Mojtaba Khomeini was named successor, Iran again fired missiles and drones at Israel and Gulf neighbours.

The state news agency in Bahrain said at least 32 people had been injured in a drone attack.

The Iranian security chief, Ali Larajani, thanked the country's clerics for defying US threats and selecting a new supreme leader despite the bombing of their council chamber in the war.

I spoke to our international editor, Jeremy Bowen, and began by asking him if the timing of the assembly's announcement is significant.

The thing to think about is, first of all, there is a man already running the war, Ali Larajani, who's the secretary of the Supreme National Security Council.

And he has been the key man, it appears anyway, in the decision-making.

He's somebody who in the past has been seen as actually something of a pragmatist.

The new supreme leader, Mojtaba Khamenei, will not have the same clout that his father built up over, well, so many years, practically 40 years.

So while no doubt he will have to try and referee between factional disagreements

within the leadership, the leadership that's still alive.
