One man was killed, and two other people were seriously injured Thursday morning when a house exploded in Powell County, the county's emergency management director said.
"The house is pretty much leveled," said the director, Danny McCormick. "We do have one that the coroner pronounced dead, that didn't make it out."
That man's identity was not released Thursday. The two injured people, who were also not identified, were flown to University of Kentucky Chandler Hospital to be treated for serious burns, McCormick said.
The explosion happened shortly before 11 a.m. Thursday on Upper Paint Creek Road, about 3 miles north of Stanton, the county seat, McCormick said.

The cause has not been determined, McCormick said: "The best that we can tell right now, it is possibly from a propane explosion from the basement area."
A Kentucky State Police arson investigator was at the site, and another investigator with the state fire marshal's office arrived later Thursday afternoon, McCormick said.
The blast blew out the basement walls of the one-story brick house, McCormick said.
"All four sides were blown out, away from the house," McCormick said. "The front door was blown out approximately 22 to 24 feet away from the door frame. All the windows were blown out into the yard area."
Firefighters from Montgomery and Clark counties responded to assist the Middle Fork, Stanton and Clay City fire departments, he said.
Firefighters were still dousing hot spots at 6:30 p.m. Thursday so that investigators could begin their work, McCormick said. Investigators will probably be on the scene Friday as well, he said.
