Kentucky A fast-moving blaze killed 10 people early Tuesday - six of them children - in Kentucky's deadliest fire in at least 30 years.
One person was injured. Neighbors said the survivor and another relative had to be prevented from running back into the flames in an attempt to rescue the screaming children.
Investigators had not determined the cause of the blaze, which broke out shortly before 4 a.m. in Bardstown.
"It may have been an explosion in the center of the house. The fire flashed very quickly," Fire Department spokesman Tom Isaac said.
Neighbor Bennie Stone said he believed some of the people were staying there with relatives because their own furnace went out. The temperature fell to 11 degrees overnight, the National Weather Service said.
