Sports stars lead tributes to brave Oscar Knox (5) after he loses his cancer battle
Little Oscar Knox, the five-year-old whose battle against neuroblastoma captured the hearts and minds of people across the world, has died.
In a tweet this morning, his family said: "Our beautiful amazing and much loved son Oscar James Knox gained his angel wings yest afternoon. Sleep tight little man Xx."
The news comes weeks after Oscar was moved into the care of the Children's Hospice following his two-year battle against the disease.
At that time, the five-year-old's suffering was so great that he told his parents: "I don't want to be a boy anymore."
In the latest update to an online diary documenting Oscar's fight, Leona wrote: "In the past four weeks Oscar has suffered more pain than we could have imagined, and more anguish than any five-year-old should ever know."
She said that she and her husband Stephen had been "pushed to the limit of what any parent could tolerate in terms of watching their child suffer".
The Belfast youngster has touched the hearts of people with his brave fight since being diagnosed with high-risk neuroblastoma – a rare and aggressive childhood cancer – in November 2011.
Oscar was an enthusiastic Celtic supporter but his campaign was also backed strongly by Glasgow Rangers fans.
When Celtic played Belfast side Cliftonville in Glasgow last summer in a Champions League qualifier Oscar was the team mascot.
Celtic chief executive Peter Lawwell said: "This is absolutely devastating news and our thoughts and prayers are with Oscar's parents, Stephen and Leona, and his little sister, Izzie, at this desperately sad time.
"We can't even begin to understand the pain of their loss, but I hope that there will be a small measure of consolation in knowing that there was genuine love and affection for Oscar from the Celtic family throughout the world.
