Former world heavyweight champion Muhammad Ali has died in a hospital in Arizona hospital.
The 74-year-old former heavyweight world champion had been hospitalised on Thursday with respiratory problems.
US media reported that the problems were complicated by his Parkinson’s disease.
Ali was known globally not only for his ring career, but also for his civil rights activism.
He has been hospitalised multiple times in recent years. Ali spent time in hospital in 2014 after suffering a mild case of pneumonia and again in 2015 for a urinary tract infection.
His Parkinson’s, thought to be linked to the punches he took during his career that spanned three decades, has limited his public speaking for years.
However, he has continued to make appearances and offer opinions through his family members and spokespeople.
