Legendary boxer, cultural icon, Muhammad Ali laid to rest

Louisville and the rest of the world said goodbye to The Greatest on Friday, showering affection on Muhammad Ali during a fist-pumping funeral procession through the streets of his hometown, followed by a star-studded memorial service where he was saluted as a fearless breaker of racial barriers.

An estimated 100,000 people holding signs and chanting, "Ali! Ali!" lined the streets as a hearse carrying his cherry-red casket made its way past his childhood home to Louisville's Cave Hill Cemetery, where a private graveside service was held for the three-time heavyweight champion of the world
