Escalating cross-border strikes since early September 2026 have intensified Saudi Arabia–Houthi fighting after the breakdown of the 2022 ceasefire. Houthi forces seized Red Sea coastal territory including Mocha, prompting Saudi-backed Yemeni government forces to launch the “Dawn of Yemen” offensive and Riyadh to resume airstrikes on Houthi positions. In response, Houthis have conducted repeated ballistic missile and drone attacks on Saudi airports—including multiple strikes on Riyadh’s King Khalid airport that killed at least 17 people and injured hundreds—plus Aramco facilities and other infrastructure. The most recent major incident occurred on October 19 when a Houthi missile killed over 50 Yemeni government soldiers at a training camp. Saudi authorities have intercepted many projectiles while continuing targeted strikes in Yemen, with traders monitoring further escalation signals, diplomatic mediation offers from Iran, and any shifts in U.S. or regional support that could alter the pace of Saudi military operations.
