The baby’s mother was taken to hospital with minor injuries and the driver of the car that exploded on the street has been arrested in the blast, Ireland’s Health Minister has said.
The blast, which occurred around 6pm on Monday at the end of the first quarter of the year, killed one person and injured at least 10 others.
A man was taken into custody in the town of Ballymurphy on Tuesday afternoon and later released pending further inquiries.
The bomb detonated in the car of a woman who was attending a home party, a garda spokesperson said.
Police have yet to establish the cause of the blast.
The woman was treated at the scene and was taken by ambulance to the Royal Hospital Dublin, where she later died.
The Irish Independent understands the man arrested in connection with the blast is the driver.
The Irish Department of Health confirmed the woman was taken hospital after the blast and is currently in hospital.
A garda spokeswoman confirmed the car was involved in a minor car accident, but declined to provide further details.
She said the woman’s name and address were being withheld pending further investigation.
The blast is being investigated as a terrorist incident.
“There are no immediate reports of injuries,” she said.”The gardaí are still investigating and are assisting the public in their inquiries.”
It is believed the car involved in the incident was involved on several occasions in similar incidents in recent months.
“It is not known what the exact motivation for the attack was or who was driving the vehicle,” she added.
Earlier this month, garda helicopters searched for the car bomb that killed three people in the city.
