Trump said the U.S. is considering joining Saudi Arabia in retaliatory strikes against Iran-backed Houthis in Yemen after a missile attack on Riyadh's main airport killed 12 people and injured 309, potentially expanding U.S. involvement in the Iran war. * Airport attacks: Saturday's strike hit King Khalid International Airport. Another projectile struck a terminal Sunday, following a Thursday attack that killed three Saudis. * Saudi response: Riyadh requested urgent U.S. defense support. The Saudi-led coalition pledged a decisive response, while Trump said no decision on U.S. involvement had been made. * Houthi threats: The group renewed warnings against using Saudi airports and continues threatening oil tanker traffic through the Bab el-Mandeb Strait, a critical Red Sea shipping route. * Military support: Washington recently approved a potential $24.3 billion F-35 sale to Saudi Arabia, pending congressional review. Britain is considering additional support but ruled out offensive operations for now. * Energy risks: Houthi disruptions in the Red Sea, alongside Iran's restrictions in the Strait of Hormuz, threaten energy shipments as the Iran war drives up global fuel prices. 11-OCT-2026 07:48 PM ET
