An American military contractor has been killed and another wounded in a shooting in the Saudi Arabian capital of Riyadh. The two are employees of a subsidiary of the Virginia-based contracting giant Northrop Grumman. The Saudi government says it has arrested a suspect who formerly worked with the two victims. In Washington, State Department spokesperson Jen Psaki said the United States has issued a security advisory to Americans in Saudi Arabia.

Jen Psaki: “Obviously, we evaluate our security posture when incidents occur. Certainly, we’re in the process of evaluating our security posture. We’ll take appropriate steps to ensure that all of U.S. mission personnel are safe, of course. We typically issue — our embassy is issuing, I should say, a security message to U.S. citizens to advise them on the situation and any safety precautions.”
