Three children have died in a house fire in the Australian state of New South Wales, police say.
Firefighters were called to the home in Singleton, 200km (120 miles) north-west of Sydney, at about 03:30 local time on Wednesday (17:30 GMT Tuesday).
The body of a boy, 11, was found inside the house. Two sisters, both aged 5, were pulled from the house but died in hospital, the BBC reports.
The cause of the blaze is not yet known, authorities said.
Neighbours were able to rescue another girl, 8, and a woman, 31, who were both treated for smoke inhalation. The woman also suffered burns.
"Our fire crews arrived to find the neighbours trying to assist with hoses," said New South Wales Police Supt Chad Gillies.
Neighbours said six people had lived in the home, Australia's Nine News reported.
"I was woken up to screams... it was terrible. It was horrendous," one eyewitness told the network.
"When it is deemed safe to do so, police and fire investigators will examine the home to identify where and how the fire started," the police force said in a statement.
Supt Gillies said heating and fireplace arrangements within the home would form part of the investigation. Fire crews had heard smoke detectors upon their arrival, he added.
Police said a report would be prepared for a coroner.
Singleton is located in the Hunter Valley, a popular wine and tourism region.
