Tens of thousands of Iranians joined the funeral procession for late President Ebrahim Raisi and his entourage in Tehran on Wednesday, with the country's supreme leader Ayatollah Ali Khamenei leading prayers.
Flanked by top officials, Khamenei said prayers over the coffins of the eight dead from Sunday's helicopter crash, who also included Foreign Minister Hossein Amirabdollahian.
A sea of mourners filled the open space around Tehran University, where the prayers were held before the funeral procession moved on to Enghelab and Azadi squares.
State television said that Raisi, who had been widely seen as Khamenei's most likely successor as supreme leader, had received a "millionfold farewell" from the people of Tehran.
"We have lost a prominent personality. He was a very good brother. He was an efficient, competent, sincere, and serious official," Khamenei tolf visiting Iraqi Prime Minister Mohamed Shia al-Sudani.
The leader of the Palestinian resistance group Hamas, Ismail Haniyeh, joined the procession, as did the deputy leader of the Lebanese militant group Hezbollah, Naim Qassem.
"I say once again ... we are sure that the Islamic Republic of Iran will continue its support for the Palestinian people," Haniyeh told the crowd to chants of "Death to Israel."
In the capital, huge banners have gone up hailing the late president as "the martyr of service," while others bade "farewell to the servant of the disadvantaged."
Tehran residents received phone messages urging them to join the funeral procession.
"I was sad, I came to calm my heart and calm the heart of the supreme leader," said one mourner who gave her name only as Maryam and said she had traveled from Varamin, south of Tehran, to pay her last respects.
Raisi's helicopter crashed into a fog-shrouded mountainside in northwestern Iran on Sunday as he headed back to the city of Tabriz after attending a ceremony on the border with Azerbaijan.
A huge search and rescue operation was launched, involving help from Türkiye, Russia and the European Union. State television announced Raisi's death early Monday.
The Iranian military said Wednesday that domestically produced drones had played the key role in locating the crash site.
Funeral ceremonies for Raisi and his entourage began Tuesday with processions through Tabriz and the Shiite clerical center of Qom drawing tens of thousands of black-clad mourners.
From Tehran, the bodies will be taken to Iran's second city of Mashhad, Raisi's hometown in the northeast, where he will be buried Thursday evening after funeral rites at the Imam Reza shrine.
Khamenei, who wields ultimate authority in Iran, has declared five days of national mourning and assigned Vice President Mohammad Mokhber, 68, as caretaker president until a June 28 election for Raisi's successor.
Iran's top nuclear negotiator Ali Bagheri, who was Amirabdollahian's deputy, has been named acting foreign minister.
The country's armed forces chief Mohammad Bagheri has ordered an investigation into the cause of the helicopter crash.
Raisi was elected president in 2021, succeeding the moderate Hassan Rouhani at a time when the economy was battered by U.S. sanctions imposed over Iran's nuclear activities.
The ultra-conservative's time in office saw mass protests, a deepening economic crisis and unprecedented armed exchanges with archenemy Israel.
After his death, Russia and China sent their condolences, as did NATO, while the U.N. Security Council observed a minute's silence.
Messages of condolence also flooded in from Iran's allies around the region, including the Syrian government as well as Hamas and Hezbollah.
