Houthis claim strikes on airports, Aramco facilityThe Houthis said their operations targeted King Khalid International Airport in Riyadh, an Aramco refinery in Rabigh, Abha International Airport and a military base in Khamis Mushait, Reuters reported.

The claimed strikes mark an escalation in the Saudi-Houthi confrontation, with the conflict increasingly spilling beyond Yemen's borders and threatening Saudi economic and military infrastructure.The escalation followed territorial gains by Saudi-backed Yemeni government forces along Yemen's western coast, including areas near the strategically important Bab el-Mandeb Strait.Yemeni government forces advanced towards Mocha after recapturing areas near the strait, putting further pressure on the Houthis.The intensifying conflict has also triggered the activation of the Mecca defence pact, with Saudi Arabia, Pakistan and Türkiye moving to implement their collective-defence commitments.
