SWAT teams swarmed a house belonging to the family of a Muslim gunman who shot and killed four Marines during two brazen attacks on military sites that have been described as an 'act of domestic terrorism'. Muhammad Youssef Abdulazeez, originally from Kuwait, first attacked a recruitment center at a strip mall with an automatic rifle on Thursday before driving seven miles north in a rented silver convertible Ford Mustang to a U. Naval Reserve Center. There the year old engineering graduate, who reportedly visited the Middle East in the last two years, fatally gunned down four Marines through a perimeter fence before a local police officer shot and killed him during a brutal standoff. At least three others were injured.
