Authorities say one person suffered severe burns after an explosion at a gunpowder supplier in western Arkansas.
The Johnson County Sheriff's Office says the explosion was reported Tuesday morning at Black Powder Inc. near Clarksville.
Chief Deputy Jerry Dorney says only one person was inside the building at the time of the blast. That person was taken by helicopter to a Little Rock hospital.
The sheriff's office says the scene has been secured and investigators from the Bureau of Alcohol, Tobacco, Firearms and Explosives are responding.
