Escalating cross-border strikes and a Saudi-backed Yemeni government offensive launched in early October 2026 have heightened risks of direct Saudi military involvement in Yemen. After Houthi forces seized territory around the Bab al-Mandab Strait in September, the internationally recognized government initiated Operation Dawn of Yemen on October 4–5 to reclaim areas including coastal districts and ultimately Sanaa, with the Saudi-led coalition providing intensive airstrikes that targeted Houthi weapons depots, naval assets, and positions in multiple provinces. In response, Houthis have conducted repeated ballistic missile and drone attacks on Saudi infrastructure, including multiple strikes on Riyadh’s King Khalid International Airport that caused casualties and flight disruptions, as well as hits on Abha airport and Aramco facilities. Saudi statements emphasize defense of Red Sea navigation and security, while Turkish and Pakistani forces have deployed under a joint defense pact. Ongoing battlefield developments and Houthi retaliation patterns remain the primary drivers of trader assessments around any specific date for Saudi action.
