World mourns demise of Boxing legend Muhammad Ali

The sporting fraternity on Saturday mourned the death of legendary boxer Muhammad Ali, who passed away at the age of 74 after losing his long-standing battle against Parkinson's disease.

Former heavyweight champion Mike Tyson took to Twitter expressing his condolences, saying, "God came for his champion. So long great one. @MuhammadAli #TheGreatest #RIP."

"Inspiration, Mentor, my Friend, an Earthly God of humanity, Simply #TheGreatest #RipMuhammadAli @MuhammadAli," tweeted retired heavyweight champion Frank Bruno.

Former Filipino boxer Manny Pacquiao, on his part, also released a statement to condole the sad demise of the legendary boxer.

"We lost a giant today. Boxing benefitted from Mohammad Ali's talents but not nearly as much as mankind benefitted from his humanity," he said.

Earlier, Ali's daughter Laila Ali, also shared a touching photo on Facebook and thanked fans for their support.

The 38-year-old posted on her official Facebook page, "I love this photo of my father and my daughter Sydney when she was a baby! "Thank for all the love and well wishes. I feel your love and appreciate it!!"

Indian boxing sensation Vijender Singh also took to the micro-blogging website, saying, "@MuhammadAli sir u always be a legend ???? #RIP we always miss u."

The former three-time world heavyweight champion, who was admitted to a hospital in Phoenix, the United States with a respiratory problem, breathed his last surrounded by his family and friends.

Ali, who is also known for his civil rights activism, had been hospitalised multiple times in the recent years, including spending time in hospital in 2014 after suffering a mild pneumonia before being admitted again for a urinary tract infection last year.

The iconic figure, who also won an Olympic gold medal at the 1960 Rome Olympics, was diagnosed with Parkinson's disease in the 1980s.
