Funeral procession for Iran's late supreme leader

The funeral procession for Iran's late supreme leader Ali Khamenei and three family members has begun in Tehran, state television reported.

After lying in state in Tehran's Grand Mosalla religious complex for two days, Khamenei will be processed through the city for 10 to 12 hours, organisers said.

The 1989 funeral of his predecessor, Ayatollah Ruhollah Khomeini, drew some 10 million people, according to state news agency IRNA, and crowd surges killed more than 10 people and injured over 10,000.

Thousands had filled the Grand Mosalla yesterday, where they paid their respects to Khamenei and four family members, all killed on 28 February in Israeli airstrikes based on US intelligence.

Massive concrete walls separated the public from the coffin to prevent stampedes.

It is unclear what level of access and proximity the public will have during the procession.

But authorities are mindful that in 1989 they were forced to use a helicopter to transport Khomeini for burial after mourners stormed his vehicle, causing his burial shroud to tear and his body to fall to the ground.

As well as laying to rest the man who ruled the Islamic republic for more than three-and-a-half decades, the funerals are a chance for Iran's authorities to burnish their resilience after five weeks at war with Israel and the United States.

Iran's speaker of parliament and chief negotiator with the US, Mohammad Bagher Ghalibaf - one of the most prominent faces of the post-Ali Khamenei era - hailed on X how the "proud and invincible nation of Islamic Iran unanimously" paid tribute to its "martyr".

The procession will be followed by similar events in the clerical hub of Qom tomorrow and in Iraq's holy cities of Najaf and Karbala on Wednesday, culminating in Khamenei's burial in his hometown of Mashhad in northeastern Iran on Thursday.

Three of Ali Khamenei's sons made a rare public appearance at the funeral yesterday, further highlighting the absence of Mojtaba Khamenei, who was named supreme leader shortly after his father's killing but has yet to appear in public.

Officials have said he was wounded in the airstrikes, but the severity of his injuries remains unclear.

The new commander of the powerful Revolutionary Guards, Ahmad Vahidi, whose predecessor was killed on 28 February, appeared at the funerals for a second time, this time in the open air after he went unseen throughout the war.

Esmail Qaani, the shadowy head of the Guards' Quds Force, which is responsible for its foreign operations, also made a rare appearance.

While Iranian authorities have been keen to present a united front, none of President Masoud Pezeshkian's surviving predecessors, who had tensions in their relationship with Khamenei, have so far been seen at the ceremonies.

The government is also eager to tout the mass mobilisation in support of the authorities after mass protests in January that rights groups say were quelled by a crackdown that killed thousands of people.

The Middle East war is on hold following a ceasefire and an initial accord struck with the US.

Both the US and Iran have warned they are ready to resume military action and vengeance has been a major theme at the funerals.

Khamenei long pursued a course of confrontation with the West.

Iran for years has provided support to anti-US and anti-Israel armed groups around the Middle East, including Palestinian Hamas and Lebanon's Hezbollah, who both sent delegations to the ceremonies.
