Three men have died following car crashes, bringing the death toll on the country's roads to six in 24 hours.
Two men, aged 21 and 24, died after an accident on the Hartstown Road in Dublin early on Monday morning and a tractor driver in his 50s was killed when his vehicle overturned on the Cootehill to Mountain Lodge Road in Cavan late on Sunday evening.
The deaths followed an incident in Co Galway on Sunday afternoon when two young sisters were knocked down and killed.
Two-year-old Kate Gilmore and her baby sister Grace, aged just two months, were out for a Sunday family walk with their father John on the outskirts of the town of Tuam when they were all struck by a car at lunchtime.
They were on the hard shoulder of the busy N17 when the vehicle came off the road and ran into them.
The girls' father and the man who was driving the car, its sole occupant, were taken to University College Hospital in Galway. The men's injuries were described as not life-threatening.
Later on Sunday, a man in his 30s was killed when his motorbike collided with a car on the R618 near Dripsey in Co Cork.
