HUNTSVILLE, Ala. (AP) - Federal authorities say two Cullman men have been sentenced to 40 months in prison on explosives charges after pipe bombs were detonated in Cullman in December.

Chief U.S. District Judge Sharon Lovelace Blackburn sentenced 22-year-olds Joshua Kirk Kugler and Billy Scott Simmons for possessing unregistered destructive devices, transporting and receiving explosives, and making a destructive device.

Authorities said both men pleaded guilty to the charges in February.

The judge ordered them to serve two years of supervised release after completing their prison terms.

Authorities said the men created three pipe bombs and detonated them near a car wash and trucking company on the night of Dec. 9.
