Saudi Arabia said Yemen's Houthi rebels attempted to strike Riyadh with a ballistic missile, marking the first reported targeting of the capital since fighting escalated with the Iran-backed group. The Saudi-led coalition (military alliance) said it intercepted the missile after the morning attack and thwarted further attempts against civilian infrastructure in Yanbu, Taif, Baysh and Farasan. The Houthis claimed they had struck sensitive sites in Riyadh and Saudi Aramco facilities in Yanbu, causing massive fires, but provided no evidence, and the Associated Press could not independently verify the claims. Houthi military spokesperson Brig. Gen. Yahya Saree said the group used cruise and ballistic missiles and drones, while also alleging that Saudi Arabia targeted Sanaa. The conflict is the latest front to emerge from the Iran war and has increased pressure on markets near another major global shipping corridor. Saudi Arabia's civil defense said debris from an intercepted Houthi drone killed a Yemeni resident of Saudi Arabia on Thursday, the first reported civilian casualty. Saudi Arabia also said on Wednesday that it intercepted a Houthi drone aimed at Mecca, a claim the Houthis denied. Regional officials told the Associated Press that Saudi Arabia was running low on missile interceptors and had sought air-defense support from France, Britain, Pakistan and Egypt.
