Gardaí say they're now treating last night's fire at a flats complex in Dublin as suspicious.
It's understood it broke out at around a 11pm at an apartment block on Tyrone Place in Inchicore.
Neighbours helped rescue a mother and her three children from their flat .
The woman in her 30s and her 8-year-old son are in a critical condition in hospital.
A 12-year-old boy was also taken to Crumlin Children’s Hospital for treatment, while a 7-year-old girl has been brought to Temple Street Hospital.
Five units of Dublin Fire Brigade attended the scene, and local TD Brid Smith says firefighters worked hard to contain the blaze.
Gardaí are conducting a technical examination of the scene, and confirmed this evening that they are treating the incident as suspicious.
