A U.S. Marine was shot and killed early Tuesday morning while on duty at the Marine Barracks in Washington, D.C., the Marine Corps said in a statement.

The Metropolitan Police Department responded to the scene after the gunshot at approximately 5 a.m.

The incident is under investigation and the Marine’s name is being withheld pending next of kin notification. Police say the fatal shot was not self-inflicted. 

The Corps said there's no threat to local residents as the shooting occurred on the Marine Barracks grounds, located in Southeast D.C.

“The command's priorities are to take care of the Marine's family and friends,” Marine Barracks commanding officer Col. Don Tomich said in the statement. 

“We want to ensure these personnel are being provided for during this challenging time.”
