Three soldiers were killed in a shooting inside a Marine Corps base in America

U.S. troops killed two of his colleagues before committing suicide at the Marine Corps base in Quantico, Va., said base commander said Friday.

Said Colonel David Maxwell, said the incident occurred late yesterday in a military school barracks, located Quantico just outside Washington, DC.

The two victims, a man and a woman, both from workers and pedestrian died at the scene, Maxwell said he was withholding the nationality of the victims until notification of their families.

Maxwell refuted earlier reports which said that the alleged attacker was killed in an exchange of fire with security personnel, and ongoing investigation into the incident. Earlier in the week killed seven Marines, and a number of others in an accident during a training exercise in western Nevada.
