Post mortems are to be carried out on the two children killed tragically in Co Galway yesterday afternoon.
Two-year-old Kate Gilmore and three-month-old Grace Gilmore were on a walk with their father John when they were struck by a car on the N17 in Dunmore in Tuam.
The girls were both taken to University College Hospital Galway where they were pronounced dead shortly afterwards.
They were the only children of construction engineer Mr Gilmore and his wife Michelle, who works for the Health Service Executive. Both parents are from the Tuam area.
Mr Gilmore and the driver of the vehicle have been taken to hospital with non-life threatening injuries.
Gardaí appealed for witnesses to the incident to contact Tuam Garda Station on 093-70840 or the Garda Confidential Telephone Line 1800 666 111.
