A CO Tyrone GAA club has said it is difficult to "express the sadness of the local community" following the deaths of two of its former youth members in a crash in the early hours of Monday.
Nathan Corrigan, from Garvaghy, and Peter (Petey) McNamee, from Sixmilecross, were among three young men in their twenties who died after their car was in collision with a lorry on the Omagh Road near Garvaghy, Co Tyrone, at around 1.50am.
Peter Finnegan, from Clogher, also died in the crash.
A fourth man remained seriously ill in hospital last night.
Mr Corrigan's father Damian Corrigan is on the executive committee of Beragh Red Knights GAA.
In a statement, the club said: "Words are hard to find to express the sadness of the local community about the heartbreaking events of Monday morning.
"The Executive Committee and members of Beragh Red Knights GAA would like to extend their sincere sympathies to the families and friends of Nathan Corrigan, Petey McNamee and Peter Finnegan (Clogher) after their sudden and tragic deaths and our prayers are also with the young man in hospital.
"Both Nathan and Petey were past youth members of the club.
"Nathan is a brother of Senior player Callum and son of Kate and our esteemed Club Executive member, Assistant Secretary and County Committee member Damian Corrigan."
Mr Corrigan's mother Kate Corrigan is a teacher at Roscavey Primary School.
The school extended its sympathies to the Corrigan family.
"We also extend our condolences to the McNamee and Finnegan families on the tragic passing of Petey and Peter yesterday," a statement read.
"On this the Feast of the Holy Innocents, we keep the families and friends of everyone involved in this tragedy in our thoughts and prayers at this very difficult time."
St Oliver Plunkett Primary School in Beragh, where Mr McNamee was a past pupil, extended their condolences to the men's families.
St Ciaran's College in Ballygawley also extended its sympathies to the families of past pupils Mr Corrigan and Mr Finnegan and to the family of Mr McNamee.
The parish priest in Beragh, Monsignor Colum Curry, said he visited the scene of the crash hours after the tragedy.
He told the BBC Good Morning Ulster programme: "It was a horrific accident - a lot of debris scattered over the road, the car was on its roof.
"The whole event just reminded me that life is precious and very fragile.
"There are very few words that I think can adequately speak into such terrible anguish.
"I suppose the best we can do is just try to be present and help them in some small way just to cope with the darkness of this awful event.
"It has just been a huge shock to everybody."
