A father was Christmas shopping when his four children and a young relative died in a house fire in Arizona, USA, The Eagle reports.
The fire tore through the two-storey home on Saturday evening, authorities said, leaving no survivors.
Four children, ages 2, 4, 5 and 13 were siblings, while an 11-year-old was a visiting relative.
Authorities have not released the names of the children or father.
The fire broke out in Bullhead City, 100 miles (160km) south of Las Vegas, just before 17:00 local time (1:00 GMT) on Saturday.
The preliminary investigation found that the fire originated in the downstairs entranceway, “most likely making it impossible for the children in the upstairs bedroom to get out of the residence safely”, authorities said.All five victims were found in the same upstairs bedroom.
Police say it seems the fire had made its way up the home’s only staircase, blocking their escape.
Witnesses say as the fire tore through the house during the father’s absence, frantic neighbours gathered hoses and ladders in an attempt to put out the fire.
The neighbours were unaware that anyone was inside the home, he added. If they had known, he said they would have attempted a rescue.
