Two gunmen wearing suicide bomb belts attacked a Shiite mosque in eastern Saudi Arabia during Friday prayers, an assault that killed at least two people and wounded seven, authorities said.
The attack struck the Imam Reza Mosque in the neighborhood of Mehasin, an area popular with Shiite workers of the state-run Saudi Arabian Oil Co., the world's largest oil-producing firm.
In the attack's chaotic aftermath, Saudi police fired assault rifles into the air to drive away an angry mob that surrounded a police car holding a suspected attacker, according to video shot from the scene.
Earlier this month, Saudi officials executed prominent Shiite cleric Nimr al-Nimr, who comes from the east of the country, raising tensions in the area.
