WASHINGTON, Ramadan 15, 1436, Jul 2, 2015, SPA -- Police issued an "all clear" on Thursday after a false alarm about gunshots fired at the U.S. Navy Yard in Washington, the site of a mass shooting that took 12 lives two years ago, Reuters reported. The report about shots and a possible gunman triggered an hours-long lockdown at the military facility, located just a mile (1.6 km) south of the U.S. Capitol. -- SPA 22:26 LOCAL TIME 19:26 GMT www.spa.gov.sa/w
