Trump also indicated that he would reject any successor who continues the policies associated with the late Iranian leader.

“Khamenei’s son is unacceptable to me. We want someone that will bring harmony and peace to Iran,” he stated.

He warned that installing a leader who follows the same path as the former supreme leader could force the United States back into war with Iran “in five years.”

Mojtaba Khamenei, a cleric believed to have strong ties with Iran’s powerful Revolutionary Guards, is widely considered one of the possible successors to his father, although Tehran has yet to formally announce a new leader.

Trump’s remarks came a day after the White House suggested that regime change in Iran was not the main objective of the administration’s ongoing military campaign in the region.

Iran’s Supreme Leader serves as the country’s highest political and religious authority and holds significant influence over the armed forces, judiciary and major state policies.

The leadership uncertainty follows the death of Ali Khamenei, who was killed in late February during a wave of joint airstrikes by the United States and Israel on Iranian military and government targets.

The attacks formed part of a major military campaign launched amid escalating tensions over Iran’s regional activities and nuclear programme.

The strikes reportedly targeted several strategic facilities in Tehran and other locations, triggering a wider conflict across the Middle-East.

Iran later responded with missile and drone attacks on Israeli and US-linked targets across the region, raising fears of a broader regional war and disrupting energy shipments through the Strait of Hormuz.

Khamenei, who had ruled Iran since 1989, had not publicly named a successor before his death.

His killing created a power vacuum in Tehran, prompting speculation over who might lead the country next as the conflict continues.
