U.S. warns of escalation after reported Houthi attacks on Saudi Arabia

The U.S. government says Iran-backed Houthis have carried out attacks against Saudi Arabia, including civilian airports, and has warned that the conflict could escalate rapidly.
The warning follows Saudi Arabia's reported interception of a Houthi ballistic missile aimed at Riyadh.
Further escalation involving Saudi territory could increase geopolitical risk across Middle Eastern energy markets, particularly if attacks threaten production, pipelines or regional shipping routes.
