At least 17 people have died in Saudi Arabia following a suicide bombing Saturday on a housing complex in the capital city of Riyadh. U.S. and Saudi officials said members of Al Qaeda opposed to the Saudi monarch were likely behind the attack which also injured over 100 people. At the time of the bombing the U.S. had already closed its embassy and two consulates after receiving intelligence that an attack was imminent. In May, 35 people, including eight Americans, died during an attack on a complex that housed foreign workers including many from the private military firm Vinnell. The Wall Street Journal reports that since May Saudi officials have detained 1,500 opponents of the government and have increased its already tight control over the kingdom’s media.
