Detectives in two counties are investigating the deaths of two children found dead in a car driven by their father.

Gardaí were last night waiting to question a man in connection with the death of his two children after a nationwide search for them.

What initially looked like a single vehicle accident on a sunlit afternoon turned into something far more tragic within minutes of gardaí arriving at the scene outside Westport, Co Mayo.

Two children have died in a car accident after they went missing with their father.

A pensioner died in hospital this morning following a three vehicle collision on Tuesday.
