Three people have been killed in a head-on crash, gardai have said.
The two men and one woman died when two cars collided on a minor road beside a wooded area near Corrovaddy, just outside Letterkenny, Co Donegal, at about 1am on Thursday.
Another man was rushed to hospital and is in a serious condition.
Gardai said the three bodies remained at the scene for several hours after the accident and the county coroner had been notified.
The road death toll for the week has reached double figures following the accident and it comes after the Garda Traffic Corps and Road Safety Authority issued appeals for drivers to take care on the roads as the August bank holiday approaches.
Four men were killed in a spate of crashes within hours of each other in Donegal, Meath and Kildare earlier in the week.
And a mother and her teenage son died in a crash in Co Galway on Sunday night, along with other fatal accidents in Kildare and Sligo.
