Gardai said they do not believe the children died from natural causes.

Members of the Garda Technical Bureau are currently examining the scene.

The Irish Times reports a woman in her 40s, who is believed to be the children’s mother, is being treated at Tallaght Hospital, Dublin, after she was found in a "disoriented state" outside the property at Parson’s Court, Newcastle, on Friday night.
