A U.S. Army sergeant allegedly shot and wounded five other soldiers at Fort Stewart in Georgia, using his personal handgun, officials said.
The shooting at the 2nd Armored Brigade Combat Team area was reported at 10:56 a.m and the suspect, Sgt. Quornelius Radford, was apprehended at 11:35 a.m., Fort Stewart said. All lockdown measures have since been lifted, Brig. Gen. John Lubas, the 3rd Infantry Division and Fort Stewart-Hunter Army Airfield commander, said at a news conference.
A motive is not clear, Lubas said, but the shooting involved Radford's co-workers.
Radford has been interviewed by Army investigators and is in pretrial confinement, Lubas said.
Radford has not previously deployed to combat, Lubas said.
A U.S. official told ABC News the suspect was arrested on a DUI charge earlier this year.
All five victims are in stable condition and are expected to recover, Lubas said. Two of the victims were rushed to Memorial Health University Medical Center in Savannah, which is a Level 1 trauma center, hospital officials told ABC News.
Lubas praised the "brave soldiers" who he said "immediately intervened" and, "without a doubt, prevented further casualties."
Fort Stewart is about 40 miles southwest of Savannah.
Georgia Gov. Brian Kemp said on social media, "We are keeping the victims, their families, and all those who answer the call to serve in our hearts and prayers."
President Donald Trump has been briefed on the shooting, according to White House press secretary Karoline Leavitt.
The full circumstances surrounding the shooting were not immediately clear.
Access to combat firearms on a U.S. military personnel on base is highly restricted, with guns kept stored in an armory on the base. Firearm use is limited to only when soldiers are participating in field training, and the guns are returned to the armory at the conclusion of that training.
Military personnel are allowed to have legally registered personal guns, but there are restrictions on how they can be brought onto a base.
