US fears rapid escalation in Middle East after Houthis attack Riyadh
The United States warned on Sept 19 that hostilities between Saudi Arabia and the Houthis could escalate rapidly after a missile attack targeted Riyadh for the first time since the Yemen conflict resumed. The Houthis claimed two operations targeting sensitive sites in Riyadh and Aramco facilities in Yanbu; the Saudi-led coalition said the missiles were intercepted. The clashes have disrupted Saudi oil exports and maritime traffic.
Why it matters: The strike on Riyadh and the disruption of Saudi crude exports tie the Houthi escalation to the global economy theme.
