Firefighters say a woman and her baby son are missing after a fire tore through a Sydney store.
Emergency services are involved in a delicate rescue operation with three people unaccounted for after a blaze destroyed a convenience store and adjacent units in Sydney's inner-west early on Thursday.
A search is on for the 31-year-old woman, her 12-month-old son and an unrelated 30-year-old man with firefighters concerned about the stability of surrounding buildings on Darling Street in Rozelle.
Emergency services are attempting to shore up the walls of the surrounding buildings and put cameras into voids.
Dogs are being used to try to locate the missing trio who lived in neighbouring apartments.
"It's still a rescue and horrific as the scene is down there we are still holding out hope that there are some survivors," NSW Fire and Rescue (NSWFR) Superintendent Paul Johnstone said.
"We always hold out hope. It's not a recovery operation and we're still hoping to find some survivors."
