Air raid sirens that sounded in Saudi Arabia’s capital of Riyadh on Thursday afternoon were scheduled before Saturday’s attack on two oil facilities in the country, according to the Saudi Arabian General Directorate of Civil Defense.
The General Directorate of Civil Defense alerted citizens to the siren testing on September 11 through its Twitter account. The testing was intended to check the system’s efficiency.
