DC Navy Yard Shooting 'May Be Related to US Foreign Policy'

Four people have been confirmed dead and eight injured, after a shooting at a Navy Yard in Washington DC. Witnesses say a gunman was shooting from the 4th floor at people in a cafeteria. Reports claim two or three gunmen may have been involved in the attack - though that's unconfirmed. Several civilians and police officers are among the victims. Approximately three thousand people work at the building, where the largest of the Navy's command systems is situated. For more , RT talks to political commentator John Wight.
