Houthis threaten 'swift and painful' response if U.S. joins Saudi strikes, following deadly Riyadh airport attack

Yemen's Iran-backed Houthi rebels have threatened the U.S. with a 'swift and painful' response if it joins Saudi Arabia's strikes against the group. This comes as Saudi Arabia investigates how its air defenses failed to intercept a barrage of missiles and drones fired by Houthis, including a deadly attack on Riyadh's King Khalid International Airport that killed at least 13 people and wounded over 300. The Houthis claimed responsibility for the airport strike, which occurred on Saturday, October 10, 2026.
