Successive Houthi-claimed strikes left Riyadh's King Khaled airport closed, with exile outlets reporting 14 dead after a third hit in four days, extended suspensions, empty skies, a U.S. aviation warning and BP-led withdrawals from the Riyadh energy conference. State outlets noted a Saudi projectile-reporting app and framed damage as caused by interceptors.

Tehran paired mediation offers with blame, saying it would facilitate Saudi-Yemen dialogue while the foreign ministry spokesman held continued U.S. war and blockade responsible for Hormuz insecurity and President Pezeshkian vowed not to bow to America.

Attention then shifted to London, where the prime minister said the IRGC almost certainly directed the Fairford airbase plot, summoning Iran's ambassador and sanctioning two Iranians. The U.S. and 28 allies endorsed the assessment and warned Tehran, which denied the charge and demanded evidence.
