HAMBURG, Pa. - Authorities say a pregnant woman and her two young children were killed in a fast-moving house fire in Pennsylvania.

State police in Berks County said the fire was reported shortly before 11:30 p.m. Saturday in a home in Hamburg, about 55 miles (88 kilometers) northeast of Harrisburg. Thick smoke and flames could be seen pouring out of the structure.

Police said firefighters found a pregnant woman and her 2- and 5-year-old children dead inside the residence. A man was able to escape from a bedroom window and was hospitalized with injuries.

The names of the victims have not yet been released. Authorities said the fire was extinguished early Sunday but the residence was a total loss. The cause of the blaze is under investigation.
