A fatal weekend house fire outside Halifax that left a six-year-old girl dead has now claimed the life of two other children.

Alyssa Martin, a close friend of the family living at the home, told Global News Tuesday two other children who were in the Lower Sackville duplex early Saturday morning have died in hospital.

RCMP said first responders were called to the home on Riverside Drive at around 3 a.m. A 37-yea-rold woman and two children managed to flee the burning home.

Firefighters found three children — ages five, six and nine — inside the home. A 40-year-old man and the two children were rushed to hospital. The man had been rescued by a neighbour and was listed in critical condition on the weekend.

“During this time of profound sorrow, we ask you to keep their family in your prayers as they navigate this loss,” it reads.

“Please hold your loved ones close and treasure every moment.”
