Our Lady's Hospital for Sick Children in Crumlin has said that after intensive medical investigation, the conjoined twins born yesterday are not suitable for separation.
The twins remain in a critical condition at the hospital.
They were delivered by caesarean section at the National Maternity Hospital on Holles Street in Dublin, where their mother remains in care.
The parents have asked the public to pray for the twins and all concerned. They have also requested that their privacy be respected at this difficult time.
The birth of conjoined twins is rare, occurring an average of once in every 200,000 births, meaning Ireland can expect only one set every four years.
