The father of a 13-year-old boy who died after an incident in his school playground has paid tribute to his "special" son.
Oisin McGrath was taken to hospital from St Michael's College in Enniskillen on Monday and died on Thursday evening.
On medical advice, his parents made the agonising decision to withdraw life support and donate their child's organs for transplant.
On the "RIP Oisin McGrath" page on Facebook, his father Nigel wrote that his special son would be forever missed and was now saving lives.
The schoolboy's funeral will take place at Holywell Catholic Church in Belcoo, County Fermanagh, on Sunday morning.
Parish priest Father Seamus Quinn said the teenager's death in such circumstances was every parent's worst nightmare.
He said: "There are no words to describe what they're going through.
"They're devastated, they're numb, they're in shock. It's a nightmare, except this one you don't wake up from. It's horrendous."
St Michael's College, which remained closed on Friday, asked students attending the service to wear uniform.
A 17-year-old student from the school was questioned following the incident but released on bail pending enquiries.
Northern Ireland First Minister Peter Robinson tweeted: "Young Oisin McGrath's death is heartbreaking. I'll be praying for his family and all those devastated by this sad news."

Education Minister John O'Dowd said: "I am deeply saddened at the tragic death of Oisin McGrath. As a parent myself I can only imagine the grief his parents and family are feeling.
"My thoughts and prayers are with them at this terrible time. I also extend my sympathy to the whole St Michael's College community.
"The Western Education and Library Board is providing counselling and pastoral support to the school and will continue to do so for as long as is needed."
