The two children at the centre of a special garda cross-border appeal earlier today have been found dead.
The bodies of brothers Eoghan (10) and five-year-old Ruairi were found in a car, in Westport, Co Mayo at approximately 4pm.
The scene has been sealed off and an examination is underway.
The State Pathologist has also been called and a full garda investigation is underway.
An alert for the two brothers – the first such alert on the new emergency child rescue system – was issued shortly before 2pm earlier today.
The two young boys were last seen with their father Sanjeev Chada (43) at 6.30pm last night on their way from their home in Ballinkill, Bagenalstown, Co Carlow, to go bowling.
It is the first time a Child Rescue Ireland (CRI) alert has been issued for missing children since the system was put in place last year.
The father and his two sons were reported missing at 1.30am this morning.
Mr Chada left the family home with the youngsters to go to the Dome Bowling Centre in Carlow town and had not contacted his family since.
He was reported as driving a green Ford Focus, with the registration number 06 CW 238.
Garda sources said Mr Chada was not estranged from the mother of their children and that they are not aware of any difficulties in the couple's relationship.
