US warns of rapid escalation in Middle East conflict as Yemen strikes intensify

The United States warned that the conflict between Saudi Arabia and Iran-backed Houthi forces could "escalate rapidly" after a missile attack targeted Riyadh for the first time since the Yemen war resumed, prompting Washington to urge Americans to reconsider travel to the region. The State Department also restricted travel for US government employees to Saudi cities Taif and Yanbu, while President Donald Trump cut short a Camp David weekend without explanation. The Houthi offensive has killed hundreds and displaced over 110,000 people, disrupting Saudi oil exports and maritime traffic. Washington has sent mixed signals, reportedly refusing a Saudi request to strike the Houthis, while Turkey offered military assistance to Saudi Arabia and Pakistan. The Houthis have seized Yemeni coast near the strategic Bab al-Mandab strait, critical for global shipping.
