Authorities say a driver suspected of firing a gun at motorists on an Alabama highway and exchanging gunfire with officers has been killed.

Alabama State Troopers say the ordeal began around 7 a.m. Tuesday in Blount County, where 911 dispatchers got word that someone was opening fire on motorists on U.S. 278. They say they found a vehicle matching the description around 8:15 a.m. on another highway, and the driver fled from officers, touching off a pursuit.

Authorities say the vehicle crashed, and the driver exchanged gunfire with law officers. He was later pronounced dead.

The suspect's name wasn't released, nor was the officer's. No other details, such as the race of the suspect or the officer, were immediately released.

Blount County is about 45 miles northeast of Birmingham.
