Three-time heavyweight champion Muhammad Ali transcended the world of sport, and here is how...
The 20th-century icon has died in Phoenix, Arizona, at the age of 74, having suffered from Parkinson's disease since 1984 - three years after he retired from the sport.
In the days before his death, Ali had been admitted to hospital in Phoenix, Arizona, suffering from respiratory issues.
His career spanned three decades, winning 56 of his 61 fights, but Ali was also also a civil rights campaigner who transcended sport and race.
Ali turned professional in 1960, having won the Olympic light-heavyweight gold, and was world heavyweight champion from 1964 to 1967, 1974 to 1978 and 1978 to 1979.
Mike Tyson tweeted: "God came for the champion. So long great one."
Former heavyweight boxing champion Evander Holyfield said: "To take it upon yourself and say; 'I'm the greatest', you put yourself in a position for people to take pot shots at you.
"This is what Ali did. It's amazing him becoming three-time heavyweight champion of the world."
