Yemen's Houthis have claimed fresh drone attacks deep inside Saudi Arabia for a second straight day, escalating tensions with Riyadh. The Iran-backed group said two operations targeted Najran, with one drone allegedly striking a sensitive site at the city's airport and another targeting an Aramco facility. Houthi spokesman Yahya Saree claimed both attacks achieved their objectives and linked them to alleged Saudi drone incursions over Yemen's Saada governorate. The claims follow Houthi assertions of major Saudi losses a day earlier. Is Riyadh now facing a renewed Houthi campaign inside the kingdom?
