Fort Knox on lockdown after shooting

The U.S. Army base in Fort Knox, Kentucky had heightened security in place following a reported shooting near a human resources facility there. It was unclear whether there had been casualties. 

The U.S. Army base in Fort Knox, Kentucky, was placed on a security lockdown on Wednesday after a report of a shooting near a human resources facility at the post, Fox News reported.

A switchboard operator at the base confirmed to Reuters that a lockdown was in effect, but gave no details. A spokesman at the base said he could not immediately confirm that there had been a shooting.

According to the Fox News account, which cited an unnamed base spokesman, it was not immediately known if there were any casualties.

Mary Trotman, a spokesperson for the FBI in Louisville, said two agents had been dispatched to Fort Knox to assist with the investigation.

Trotman said the shooter or shooters had not been apprehended to her knowledge. She had no further details on the incident.

Fort Knox, near Louisville, is home to more than 40,000 U.S. military personnel, family members and civilian employees.

In February, local media reported that a soldier and his wife died of gunshot wounds at their home on the base in what the Army said appeared to be the result of a domestic dispute.

Wednesday's incident came less than two weeks after a U.S. Marine shot two colleagues to death at the Marine Corps base in Quantico, Virginia, before killing himself.
