Boxing legend Muhammad Ali has died at the age of 74, a spokesman for his family has confirmed.
The three-time world heavyweight champion had 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 suffering from respiratory problems, with reports suggesting the breathing problems had been complicated by his neurological disorder.
A statement from spokesman Bob Gunnell said: "Muhammad Ali's funeral will take place in his hometown of Louisville, Kentucky.
"The Ali family would like to thank everyone for their thoughts, prayers, and support and asks for privacy at this time."
Boxing manager and promoter Frank Warren told Sky News: "The world has lost an iconic figure. As a boxer, he was one of the greatest of all time.
"Not only that, but he crossed over into the mainstream and became bigger than sport. He was probably one of the most recognised people on the planet.
"Muhammad Ali probably paved the way for Barack Obama becoming President of the United States. He changed the whole concept of being black in America."
Fellow boxing champion Roy Jones Jr tweeted: "My heart is deeply saddened yet both appreciative and relieved that the greatest is now resting in the greatest place.
"May God bless the family and all of us that are left behind that were deeply touched by his life. There will never ever be another one like him."
