Nine people were killed, including eight children, in a western Kentucky house fire early Thursday morning, News Channel 5 reported.

Greenville Assistant Fire Chief Roger Chandler says 11 people lived at the home in Muhlenberg County, which is about 130 miles southwest of Louisville in the state’s western coal fields. Officials told local media that two parents lived in the house along with their nine children.

News Channel 5 reported that an adult and child were able to escape from the fire and were transported on LifeFlight to Vanderbilt University Medical Center in Nashville, Tenn., for treatment.

Chandler said the blaze was reported at 2 a.m. CST Thursday, and crews were still at the scene four hours later. He said the cause of the fire was under investigation by the Kentucky State Police.
