Members of the Bray Travellers Community Development Group say they're devastated by yesterday's apartment fire in Clondalkin.
A mother and three young children died in the blaze at a domestic violence refuge, while a woman in her 30s is still fighting for her life.
27 year-old Annmarie O'Brien, who was killed in the tragedy, was originally from the Fassaroe area of Bray and was related to some of the victims of the Carrickmines fire in 2015.
She was seven months pregnant and her two year old daughter Paris also died in the fire; along with their cousins three year old Holly and four year old Jordan.
Their mum Biddy O'Brien is the only survivor and she remains in a critical condition.
The fire broke out at 2:30am at a complex off Kilcronan Avenue that acts as a temporary accommodation for victims of domestic abuse.
5 people were in the apartment in Cluainin Cronan at the time, two women and three children.
6 units of the fire brigade attended the scene, along with emergency services and gardai.
Gardai are investigating if the fire was the result of an electrical fault and forensic tests will be carried out at the first floor flat today.
A 27 year old pregnant woman and two little girls aged 2 and 3 were taken to Tallaght hospital and pronounced dead a short time later.
Another woman in her 30s was taken to St. James and a 4 year old boy was brought to Crumlin Children's hospital where he died yesterday evening.
It's believed that everybody in the apartment was asleep when the fire broke out.
Seven residents of nearby apartments were evacuated and two were taken to hospital for smoke inhalation.
