Prayers will be held in Wicklow this afternoon for the victims of a fire at a domestic violence support facility in Dublin.

27-year-old Annmarie O'Brien, her two-year-old daughter Paris, and their cousins three-year-old Holly and four-year-old Jordan were killed in the blaze that broke out on Wednesday morning in Clondalkin.

Brigid O'Brien remains in a critical condition in hospital, where her family are keeping a bedside vigil.

Sonas Domestic Violence Charity expressed 'devastation' over the deaths in their Clondalkin supported housing complex.

Its CEO Fiona Ryan said: "Our sympathies and condolences are with the relatives and friends of the deceased and all those impacted by this awful tragedy.

"We are devastated by the tragic loss of life which occurred as a result of fire in an apartment in our supported housing complex in Clondalkin."

Sinn Féin's Eoin O'Broin says the community has been left devastated.

"Personally and the wider community here in Clondalkin are still very, very shocked at the scale of the loss for the O'Brien and extended family.

"I think today's prayers in Bray are obviously an opportunity for people right across the city and counties to express their sympathy with the family

"I'd also expect tomorrow to see a very, very large attendance at the funeral in Shankill".
