Among those attending the service were King Abdullah of Jordan.

Turkish President Recep Tayyip Erdogan attended Thursday's prayer ceremony and had been due at the service, but cut short his visit to the US. The reasons for his departure are not clear, though there are reports of differences with the funeral's organisers.
Rose petals

The motorcade procession began at about 10:35 local time (14:35 GMT), more than an hour behind schedule, and took the coffin past Ali's childhood home, then the Ali Center, the Center for African American Heritage and then down Muhammad Ali Boulevard.
Onlookers lining the roadside waved, took photos and chanted "Ali, Ali" as a cortege led by the hearse carrying his coffin drove through the downtown area.

Fans threw flowers at the hearse and rose petals were scattered along the route.
In one neighbourhood, several young men ran alongside the vehicle carrying a placard which read: "Ali is the greatest, thanks 4 all the memories."

The cortege then brought the coffin to the Cave Hill cemetery, where Muhammad Ali was buried in a private ceremony. Actor Will Smith and ex-boxer Lennox Lewis were among the pallbearers.
