Yemen’s Houthi armed group attacked Abha, Khamis Mushait, Najran and Jizan in southern Saudi Arabia on September 8, setting fires at energy and utility facilities and temporarily suspending some operations. Saudi Arabia’s Energy Ministry reported more than 70 injuries, while the Saudi-led coalition reported 73 injured civilians and residents and pledged a decisive response. Front-month Brent crude rose to $99.2 a barrel and West Texas Intermediate reached $94.5 in early European trading. London’s FTSE 100 fell 0.6% to 10,816.59 points by 1022 GMT as higher oil prices revived inflation concerns, although BP and Shell gained. The attacks followed earlier strikes on the Jizan refinery complex, which can process 400,000 barrels a day and has remained offline since July, while traders monitored shipping risks, possible retaliation and whether disruption would spread to Saudi Arabia’s core oil infrastructure.
