Israel vows to assassinate successor to Iran’s Ayatollah – as Khamenei’s son is named the favourite to replace him

Israel’s Defence Minister Israel Katz threatened on Wednesday to assassinate any Iranian leader picked to succeed supreme leader Ayatollah Ali Khamenei, who was killed in US-Israeli strikes on Tehran.

This comes as Mojtaba Khamenei, the son of Ayatollah Ali Khamenei, has been named the favourite to be appointed Iran’s new Supreme Leader. 

In a post on X, Katz said: ‘Any leader selected by the Iranian terror regime to continue leading the plan for Israel’s destruction, threatening the United States, the free world and countries in the region, and suppressing the Iranian people, will be a certain target for assassination, no matter his name or where he hides.’

Mojtaba, 56, Ali Khamenei’s second oldest son, has strong links to the Iranian Revolutionary Guard Corps (IRGC), and was chosen by Iran’s Assembly of Experts ‘under pressure from the Revolutionary Guards’, according to Iranian opposition outlet Iran International.

Mojtaba is not a high-ranking cleric, has never held office and does not have an official role in the regime.

But he served in the Iranian armed forces during the Iran-Iraq war and is believed to wield considerable influence behind the scenes. He has been touted as a possible successor to his father for years.

However, he was not included in a list of three senior clerics Ali Khamenei reportedly identified last year.

And his father is said to have indicated opposition to his candidacy because it would resemble the hereditary rule enacted by the US-backed Shah monarchy before it was overthrown in the Iranian Revolution in 1979.

Father-to-son succession is also viewed negatively in the Shiite Muslim clerical establishment in Iran.

But much of Iran’s top brass has been decimated in the latest conflict and Mojtaba has close ties with the powerful IRGC and the Basij volunteer paramilitary force.

This comes as it was recently revealed that Mojtaba was repeatedly treated for impotency at hospitals in the UK, according to a secret US intelligence document. 

According to a classified briefing sent by the State Department to the US Embassy in London in 2008, and later released by WikiLeaks, Mojtaba was placed under pressure by his family to produce heirs.

It required four visits to the Wellington and Cromwell Hospitals, including a final stay lasting two months, and he eventually had a son who was named ‘Ali’ after the baby’s grandfather, the then Supreme Leader.

The intelligence also detailed how ‘within the Supreme Leader’s office, Mojtaba works in his father’s shadow,’ and that he traveled with him in Iran and had a’ fair degree of control over access to his father.’

He was ‘widely viewed within the regime as a capable and forceful leader and manager who may someday succeed to at least a share of national leadership. His father may also see him in that light.’

He was said to be ‘close to and well briefed by’ the senior leaders of the Islamic Revolutionary Guard Corps (IRGC), however was seen as weak in clerical terms.

‘(He) is not expected ever to achieve by his own scholarship the status of ‘mujtahid,’ far less that of ayatollah,’ the report said.

However, in the wake of his father’s death, this may change.

Under Iran’s Islamic guardianship system, the Supreme Leader must be a senior leader with significant political authority.

While Mojtaba has not held senior political roles, he studied under religious conservatives in Islamic seminaries in the Shiite holy city Qom.

Born in 1969 in the holy city of Mashhad, he grew up as his father was helping to lead the opposition to the Shah.

His wife Zahra Adel and his mother, Mansoureh Khojasteh Bagherzadeh, are among the dead from Saturday’s strikes.

The regime’s 88-person assembly is tasked with appointing, supervising and potentially dismissing the supreme leader.

It met on Tuesday in Qom to find a successor to Ali Khamenei, who was killed on Saturday by joint US-Israeli strikes.

Israeli and US strikes flattened the building where the assembly met. There was no information on any potential casualties.

US President Donald Trump said on Tuesday that he fears Iran’s new leader would be ‘as bad as the previous person’. 

Commenting on the ‘worst case scenario’ at an Oval Office news conference, Trump said: ‘I guess the worst case would be we do this and then somebody takes over who’s as bad as the previous person, right? That could happen. We don’t want that to happen. It would probably be the worst.’

He added: ‘You go through this and then in five years, you realise you put somebody in who was no better. So we’d like to see somebody in there that’s going to bring it back for the people.’ 

However, he also expressed confidence on joint US-Israel military capabilities, saying: ‘We have them very much beaten militarily, from the military standpoint. They’re still lobbing some missiles,’ he said. 

‘They won’t even be able to do that because we’re hitting all of their carriers. We’re hitting all of their missile stock … and we’re knocking out a lot.’

The conflict is now entering its fifth day, with strikes continuing throughout the night.

Israel launched new strikes on military targets in Tehran after an Iranian drone sparked a fire at the US consulate in Dubai.

Iran carried out retaliatory attacks on Middle East Gulf states, targeting US bases including a CIA station at the US Embassy in Saudi Arabia, while the US Consulate in Dubai was also rocked by a drone strike.

The Lebanese capital Beirut was rocked by explosions shortly after midnight as Israel and Hezbollah traded strikes and rocket fire.

Lebanese state media later said Israeli strikes had hit a hotel in the Beirut suburb of Hazmieh, as well as a four-storey building in the eastern city of Baalbek, where five people were reportedly killed. 

Meanwhile, Iran’s Revolutionary Guards have today declared they have ‘complete control’ of the crucial Strait of Hormuz

Iranian forces say any vessels seeking to pass the strait – a vital route for world oil and gas supplies – risked damage from missiles or stray drones.

It comes as US President Donald Trump said yesterday the US Navy was ready to escort oil tankers through the crucial Gulf passage

The Guards said they had also launched more than 40 missiles at US and Israeli targets in a new wave of strikes
