The principal of the college where one of the young people who died in a road crash in the Republic of Ireland taught said it is a "major challenge" to convey what has happened to the students.

Chloe McGee, 23, and Shay Duffy, 21, both from Carrickmacross, County Monaghan; Alan McCluskey, 23, from Drumconrath, County Meath; Dylan Commins, 23, from Ardee, County Louth, and Chloe Hipson, 21, from Lanarkshire in Scotland were killed on the Ardee Road at Gibstown, near Dundalk, just after 21:00 (local time) on Saturday.

They were travelling in a car which collided with another vehicle.

Three others - two men and a woman - are being treated for non-life-threatening injuries.
