Yemen’s Houthi movement said it struck Saudi Aramco oil facilities at Jizan and Yanbu on the Red Sea, while Saudi-backed Yemeni forces and a Saudi-led coalition also attacked Houthi positions. The incident raises fears that the wider conflict involving Iran, the United States and Gulf states could spread further into Yemen and threaten another crucial oil-shipping route.

Reuters verified video showing smoke near Jizan’s Aramco refinery, and trading sources reported possible damage to fuel and oil storage there; the refinery can process 400,000 barrels a day. Two missiles aimed at Yanbu, Saudi Arabia’s main Red Sea oil export port, were reportedly intercepted by a Greek-operated Patriot battery, while Brent crude briefly rose above $100 a barrel amid supply concerns.
