Yemen’s Houthi armed group launched attacks on September 8 across Abha, Khamis Mushait, Najran and Jizan in southern Saudi Arabia, where fires at energy and utility facilities caused temporary operational suspensions. Saudi Arabia’s Energy Ministry said the strikes injured more than 70 people, while the Saudi-led coalition reported 73 civilian and resident injuries and promised a decisive response. Brent crude rose 1.65% to $98.65 a barrel and WTI gained 2% to $93.31 as markets assessed the risk to regional supply. The escalation followed a September 7 Houthi ballistic-missile attack on a Saudi military supply convoy and renewed strikes on the Jizan refinery complex, a 400,000-barrel-per-day facility that has remained offline since a July attack. The Houthis have also attacked Saudi tankers since declaring a maritime blockade on July 20. The Chinese Embassy in Saudi Arabia urged citizens and institutions to monitor developments and take security precautions. Markets are watching for a Saudi-led retaliation and any expansion of Houthi operations toward core oil-producing areas or export infrastructure.
