The death toll in a Sydney boarding house fire from an explosion has climbed to three, after two more bodies were found in the smoking rubble, with police investigating the blaze as a murder.
"There was an explosion here at Newtown. It is unclear exactly at this stage what the cause of it is," Assistant Police Commissioner Peter Cotter told reporters on Tuesday.
"We are treating this as a murder. We are treating this as a maliciously lit fire."
