Yemen's Houthi rebels launched attacks on September 8 against multiple cities in southern Saudi Arabia, including Abha, Khamis Mushait, Najran, and Jizan. These attacks resulted in fires at several energy and public facilities, causing partial operational disruptions and injuring over 70 people. A Houthi spokesperson announced on the same day that the group would declare extensive military operations deep within Saudi territory, signaling a significant escalation in the conflict. In response, international oil prices rose sharply, with Brent crude up 1.65% to $98.65 per barrel, nearing the $100 mark, and WTI crude up 2% to $93.31 per barrel.
