WASHINGTON: A US Marine shot and killed at least one person at a military base in Virginia and has barricaded himself inside a building, US media reported early on Friday.

Media reports said the shooting happened Thursday night at Marine Base Quantico in the state bordering Washington, DC. The base went into lockdown immediately after the shooting, but this has since been lifted. Police are in a standoff with the shooter.

The suspect is a Marine who attended officer candidate school at the base, CBS News reported, quoting First Lieutenant Augustin Solivan.
