United States President Donald Trump says Iranian Supreme Leader Ayatollah Ali Khamenei is dead after Israeli-US attacks on Iran.

Trump wrote in a post on his Truth Social platform that 86-year-old Khamenei was killed in the joint US-Israeli strikes, which began early on Saturday.

“He was unable to avoid our Intelligence and Highly Sophisticated Tracking Systems and, working closely with Israel, there was not a thing he, or the other leaders that have been killed along with him, could do,” the US president wrote.

“This is the single greatest chance for the Iranian people to take back their Country,” he said. “Hopefully, the IRGC [Islamic Revolutionary Guard Corps] and Police will peacefully merge with the Iranian Patriots.”

Earlier, Israeli Prime Minister Benjamin Netanyahu claimed there were “growing signs” that Khamenei had been killed.

Additionally, the Reuters news agency, citing an unnamed senior Israeli official, reported that Khamenei’s body has ⁠been located.

But Iran’s Tasnim and Mehr news agencies reported that Khamenei remained “steadfast and firm in commanding the field”.

In what appeared to be a response to the claims, the head of public relations at Khamenei’s office accused the country’s enemies of “mental warfare”.

“The enemy is resorting to mental warfare; all should be aware,” the official was quoted as saying by Iranian state media.

Reporting from Tehran, Al Jazeera’s Tohid Asadi said there has so far been no official confirmation of Khamenei’s killing from Tehran.

He noted that Iranian Minister of Foreign Affairs Abbas Araghchi told NBC News earlier that, “as far as I know”, Iran’s supreme leader, as well as other top Iranian officials, remained in good health.

Khamenei has been Iran’s supreme leader since 1989, succeeding the founder of the post-shah Iran, Ayatollah Ruhollah Khomeini, who steered Iran’s 1979 revolution.

The supreme leader holds ultimate authority over all branches of government, the military and the judiciary, while also acting as the country’s spiritual leader.

Barbara Slavin, a distinguished fellow at the Stimson Center in Washington, DC, told Al Jazeera that Iran “has a plan” in place in the event that Khamenei’s death is confirmed.

“There will probably be a council that will be set up to run the country. It may already have been running the country, as far as we know,” she said.

Saturday’s strikes on Iran targeted 24 provinces, killing at least 201 people, according to Iranian media reports, citing the Red Crescent.

Among the attacks, Israel struck two schools in Iran, killing at least 108 people at the Shajareh Tayyebeh girls’ elementary school in the southern city of Minab, and two others at a school east of the capital, Tehran.

Netanyahu said in his address that many “senior figures” had been “eliminated” in the wave of attacks targeting senior leaders, as Trump called for the government to be toppled.

Israel, he said, had killed “commanders in the Revolutionary Guard and senior officials in the nuclear programme. And we will continue.”

Trump indicated on his Truth Social post that “heavy and pinpoint bombing” of Iran would go on “uninterrupted throughout the week or, as long as necessary”.

Iran’s counterattacks on Saturday triggered air-defence interceptions in several countries where airbases with US assets are hosted, including Kuwait, Qatar, the United Arab Emirates and Bahrain.

On Saturday evening, the Iranian Revolutionary Guard Corps (IRGC) said that the third and fourth waves of “retaliatory” strikes on US and Israeli positions were ongoing, according to a statement carried by the IRNA news agency.

United Nations Secretary-General Antonio Guterres told an emergency meeting of the Security Council that he deeply regretted that an opportunity for diplomacy had been “squandered”.

“Military action carries the risk of igniting a chain of events that no one can control in the most volatile region of the world,” he told the 15-member body. “I call for de-escalation and an immediate cessation of hostilities”.

He said he was not in a position to confirm Israeli reports of the death of Khamenei.

Addressing the Security Council, Iran’s UN ambassador, Amir Saeid Iravani, said the US and Israel had “initiated an unprovoked and premeditated aggression”, attacking “civilian populated areas in multiple large cities of Iran, where millions of people reside”.

“This is not only an act of aggression, it is a war crime, and a crime against humanity,” he said.

The US ambassador to the United Nations, Mike Waltz, insisted the military action was lawful. “Iran cannot have a nuclear weapon,” he said. “That principle is not a matter of politics. It’s a matter of global security.”

China’s UN ambassador, Fu Cong, said Beijing was very concerned by “the sudden escalation of regional tensions”.

Russia’s ambassador, Vassily Nebenzia, condemned the US-Israeli air strikes, demanding that the US and Israel “immediately cease their aggressive actions”.
