An explosion during a training exercise injured eight U.S. special operations forces Thursday at Fort Bragg, according to an Army spokesman.

The soldiers were taken to the Womack Army Medical Center for treatment, said Lt. Col. Rob Bockholt, a spokesman for the U.S. Army's Special Operations Command, which is based at Fort Bragg.

Bockholt said he didn;t know the extent of the soldiers' injuries.

"There was an incident that occurred on one of the ranges,'' Bockholt said, adding that the command is investigating. "We're looking into exactly what happened.''

About 57,000 military personnel are attached to Fort Bragg. It's the largest Army installation by population and covers about 161,000 acres.

The Army's Special Operations Command has about 23,000 soldiers spread across several sites.
