Eight units of Dublin Fire Brigade were called to deal with a fire at an apartment block in Tallaght last night.
The blaze broke out in the underground car park of the building on Main Street.
The fire was started by a gas leak, and crews from ESB and Bord Gais attended the scene.

At around 2.45am, Dublin Fire Brigade said: "The majority of residents can now access their apartments, [while] a small number will be rehoused."
