Washington, Dhu-AlQa'dah 11, 1436, Aug 26, 2015, SPA -- The White House says the shooting of two TV journalists on the air illustrates that gun violence has become too common in the United States and that steps should be taken to tighten gun laws, dpa reported. "This is another example of gun violence that is becoming all too common," spokesman Josh Earnest says. He calls on Congress to again take up gun control measures advocated by President Barack Obama after the Sandy Hook school massacre in 2012 that were rejected by lawmakers at the time. -- SPA 21:57 LOCAL TIME 18:57 GMT www.spa.gov.sa/w
