"All Soldiers were treated on-site and moved to Winn Army Community Hospital for further treatment," said a post by the official Facebook page of the base, which is located in the southern state of Georgia.

The base went into lockdown shortly after law enforcement were dispatched to respond to the incident, according to the post, which said the shooter was now in custody, but provided no details about their identity or potential motive.

"There is no active threat to the community," the post said, adding: "The incident remains under investigation and no additional information will be released until the investigation is complete."

Press Secretary Karoline Leavitt said in a post on X that President Donald Trump has been briefed on the shooting and that the White House is "monitoring the situation."

Though relatively rare, military facilities have not been left untouched by the epidemic of gun violence plaguing the United States, where conservative politicians have sought to block many restrictions on firearms.
