Saudi Arabia says four gunmen were killed and three security officers were wounded in an attack on a security building north of the capital, Riyadh. The state-run al-Ekhbariya news channel reported Sunday that police had foiled the attack in Zulfi, a city about 250 kilometers (155 miles) north of the capital. No one immediately claimed the attack, and authorities have not offered details on the identity of the assailants. Other state-linked media said the attackers had tried to ram a car through the front of an Interior Ministry building but were stopped by security in a shootout. State-linked media also reported videos circulating on social media showing dead gunmen with machine guns and explosive devices.
