State television in Saudi Arabia says a teacher has shot dead six colleagues in the kingdom's south. The station reported the shooting Thursday in a post on Twitter. It posted a still photograph that showed ambulances gathered outside of a building in Jazan province. It did not offer a motive for the shooting. Mass shootings are rare in the kingdom. Saudi Arabia has faced a series of recent attacks by Islamic State militants (ISIS). http://english.ahram.org.eg/News/187322.aspx
