Mourners dressed in black gather just south of Qom in Iran for the funeral service of the country's late Supreme Leader Ayatollah Ali Khamenei with throngs of people surrounding the truck carrying his coffin.

Mourners dressed in black gathered just south of Qom in Iran for a for the funeral service of the country's late Supreme Leader Ayatollah Ali Khamenei's with throngs of people surrounding the truck carrying his coffin.

Iranian state television early Tuesday aired live images from a helicopter of hundreds of thousands of people walking toward Jamkaran Mosque.

The mosque is believed by Shiites to have once hosted Muhammad al-Mahdi, the 12th and last Shiite imam, who disappeared in the 9th century and will one day reappear to bring justice to the world.

Images of Khamenei and his son, Iran's new Supreme Leader Ayatollah Mojtaba Khamenei, were displayed on banners and posters held by mourners.

At the height of the war, before an April ceasefire, Israel targeted top Iranian leaders, in at least one case likely using their public appearances to fix their position.

It has also threatened to kill the younger Khamenei.

Authorities have shut down streets, airspace and daily life for the mourning, which began Saturday and will end Thursday as Khamenei is buried at the Imam Reza shrine in Mashhad, his birthplace.

Khamenei was 86 years old at the time of his death.

Meanwhile, a tanker travelling off the coast of Oman in the Strait of Hormuz caught on fire early Tuesday morning after being struck by a projectile, according to the British military.

The attack was the latest targeting a vessel moving through the narrow mouth of the Persian Gulf, through which a fifth of all oil and natural gas traded once passed in peacetime.

Iranian state television says the liquefied natural gas tanker came under attack after ignoring warnings but did not directly claim it carried it out.

Tehran has repeatedly declared that only its approved route through the strait is safe and is suspected of attacking other ships that have used another route close to the Omani shore.

The US is eager to press ahead with negotiations with Iran aimed at fully reopening the strait, rolling back Tehran's disputed nuclear program and reaching a permanent end to the war launched February 28th.

US President Donald Trump warns Iran they'd need to make a deal or Washington is "going to finish the job."
