Iran’s assassinated supreme leader Ayatollah Ali Khamenei was buried in the country’s holiest shrine, state media said early on Friday, after huge crowds gathered for his funeral with his son and successor, Ayatollah Mojtaba Khamenei, still hidden from public view.

The burial in Mashhad in northeast Iran follows a week of mass funeral processions, rallies and mourning ceremonies that have coincided with a renewed burst of conflict with the United States following weeks of truce in the four-month-old war.

Khamenei was assassinated in the first strikes of the war launched by the United States and Israel on February 28. The US and Iran agreed to a truce last month.

Khamenei’s body was carried slowly by truck on Thursday through the crammed Mashhad streets towards the gilt dome and minarets of the Shrine of Imam Reza as white-turbaned clerics walked on either side.

Black-clad mourners pressed close behind, waving Iranian flags, photographs of the late Khamenei and red placards with revolutionary slogans.
