Saudi Arabia and Yemen’s Iran-backed Houthi rebels have accused each other of launching attacks, putting their four-year truce at serious risk. On Monday, the Houthis alleged that Saudi forces bombed Sanaa’s main international airport to prevent an Iranian aircraft from landing. The Saudi-led coalition did not comment on the claim but said Houthi forces later fired ballistic missiles toward Saudi territory, which were intercepted by air defenses. The Houthis confirmed striking Abha airport in Saudi Arabia and warned airlines to avoid Saudi airspace. UN envoy Hans Grundberg expressed deep concern and said he was in contact with both sides to prevent escalation.

The renewed hostilities follow rising tensions since an Iranian plane landed in Sanaa on July 3, sparking disputes between Yemen’s Saudi-backed government and the Houthis. The government admitted responsibility for Monday’s strike, saying it aimed to block another Iranian flight. The Houthis blamed Saudi Arabia directly, declaring the end of the de-escalation phase. The UN warned that any escalation could worsen Yemen’s humanitarian crisis.

Fighting has also resumed in Hodeidah province, raising fears that Yemen’s fragile peace could collapse entirely.
