Thousands of people line the streets of Tehran for the funeral procession of Iranian Supreme Leader Ayatollah Ali Khamenei, who ruled Iran for more than 35 years and was killed in joint US-Israeli airstrikes last February.

The coffins carrying the remains of the Ayatollah and several relatives - killed in attacks at the beginning of the Iran war - move slowly along the 10 kilometer route.

Organizers spray water on the crowd as the Iranian capital is hit by high temperatures.

The events to bid farewell to Khameni began on Friday and will continue throughout the week. Crowds have been pouring through the Iranian capital since early Monday morning; People have been seen waving flags and holding portraits of the late Ayatollah.

It is a “carefully choreographed and deeply political” event, explained BBC News chief correspondent Lyse Doucet, as Iran's new leaders seek to convey a message of strength and resilience, both at home and abroad.

"Among the emotions there is not only grief, but also anger; the color that stands out most on the flags is red, red for blood, and for Shiite Muslims red means martyrdom... and revenge," Doucet described from the streets of the Iranian capital, where thousands around him chanted "death to the US." and “death to Israel.”

Photos of the funeral procession show some attendees carrying anti-Trump signs and banners, often with violent messages including death threats.

Also appearing are Israeli Prime Minister Benjamin Netanyahu and US Vice President JD Vance.

A video shared on Telegram by the Fars news agency - linked to the Islamic Revolutionary Guard Corps - shows attendees throwing stones from a bridge at a poster displaying the face of the American president.

In a later sequence, his image can be seen torn in two.

The funeral procession is expected to last between 10 and 12 hours in total, according to state broadcaster IRIB, which quotes an official in charge of organizing the ceremony.

Today is the last of three days of public mourning in Tehran, before the ceremonies move to the holiest cities for Shiite Muslims in Iran and neighboring Iraq.

The burial, meanwhile, is scheduled for Thursday in the northeastern Iranian city of Mashhad; Iranian authorities estimate that millions of people will attend the “funeral of the century.”

Negotiations postponed and leader absent

A fragile ceasefire currently holds between the United States and Iran as negotiations continue toward a permanent peace agreement.

These negotiations have been suspended since the funeral services began on Friday, according to US President Donald Trump.

On Saturday, Trump told the Axios news website that the Iranians were “begging for a deal,” but noted that both sides had decided to take a weeklong pause in talks until Khamenei's burial was concluded.

Iran has not formally commented on whether the talks have been suspended.

Referring to the presence of senior regime officials at the funeral, Trump said: "They're all there. One shot (and we could take them all out), but we're not going to do it because then we wouldn't have anyone to negotiate with."

Mojtaba, Khamenei's son designated as his successor, who has yet to appear in public since taking office, has been absent until the time of his father's funeral.

BBC Persian journalist Ghoncheh Habibiazad recalled that, according to Iranian media, Mojtaba was wounded in the same attack that killed the Ayatollah on the first day of the war, when the United States and Israel attacked Iran on February 28.

"Israel has sworn - both before and after his appointment - that he is a potential target of their attacks. Therefore, his absence could be due to security reasons, although the Iranian authorities have not yet offered any explanation," Habibiyazad reported.

To date, the only news about Mojtaba Khamenei since his succession in early March has come through written statements published in Iranian media. The last one aired yesterday; In it, he confirmed the head of Iran's judiciary in office for a new term.
