Israeli and US strikes have flattened the building where Iran chooses its next new supreme leader, local media reported.

‘The American-Zionist criminals attacked the Assembly of Experts building in Qom,’ south of Tehran, according to the Tasnim news agency.

Footage aired by Iranian outlets showed the complex heavily damaged in the strikes.

Iran’s supreme leader Ayatollah Ali Khamenei was killed in US and Israeli strikes on Saturday.

It comes as Donald Trump told Iran’s surviving leaders it’s ‘too late’ to talk.

Writing on his Truth Social account, the President said: ‘Their air defense, Air Force, Navy, and Leadership is gone. They want to talk. I said ‘Too Late!

Trump warned the ‘hardest hits’ are yet to come as the fighting entered its fourth day and promised to retaliate after the US embassy in Saudi Arabia was attacked by drones.

The President also claimed the initial wave of strikes wiped out Washington’s preferred successors to Khamenei.

He said the White House had shortlisted several preferred successors – but insisted the military campaign was ‘so successful’ it eliminated not only the primary options but also the ‘second or third’ choices.

‘The attack was so successful it knocked out most of the candidates,’ Mr Trump told ABC News.

Iran is thought to be considering its top security chief Ali Larijani as a choice for leader, along with Khamenei’s second eldest son Mojtaba Khamenei and Mohammad Baqer Qalibaf, speaker of the country’s parliament. 

He said 48 Iranian leaders had been killed in the bombings over the weekend, wiping out much of the country’s leadership.

The President has not revealed who was earmarked for the successor but among the dead were one of the regime’s top advisers Ali Shamkhani, commander of the Revolutionary Guard General Mohammad Pakpour and hardline former president Mahmoud Ahmadinejad.
