Saudi Arabia issued rare air-raid alerts for Riyadh and Al-Kharj early on September 19, marking the first such warnings since the escalation of hostilities with Yemen's Houthi group began in July. Residents reported hearing booms, and a large plume of black smoke was visible near King Khalid International Airport. The Saudi Civil Defense issued an all-clear on Saturday morning, though the government has not provided specific details regarding the cause of the alerts.
Regional Escalation and Warnings
The emergency alerts were transmitted by phone at 4 a.m. and 6 a.m. local time. Beyond the capital, other areas of Saudi Arabia, including the Red Sea cities of Jeddah and Yanbu, as well as Farasan Island, also received warnings. These events follow a period of heightened tension, with the Iran-aligned Houthi group launching frequent strikes against Saudi infrastructure and declaring a naval blockade against the kingdom.
Impact on Energy and Infrastructure
The ongoing conflict has increasingly targeted energy infrastructure, threatening global oil supplies as the Strait of Hormuz remains largely blockaded. Reports indicate that a recent drone attack, attributed to forces in Iraq, forced the shutdown of the East-West pipeline. Saudi Aramco is currently working to restore the pipeline's capacity. Meanwhile, the United Nations Security Council issued a statement on Friday condemning the Houthi attacks on civilian and energy facilities.
