The Principal of Largy College in Clones, Co. Monaghan says students, staff, Board of Management and parents are in deep shock following the death of two teenagers in a crash.
The 16 and 17-year-old girls died in a single vehicle crash on the way to a debs ball last night.
Two others involved in the accident - a man in his 60s and an 18-year-old girl - are both in a critical condition.
A teenage boy meanwhile, who was a passenger in the car, was treated for non-life-threatening injuries.
