Escalation between Saudi Arabia and Houthi forces in Yemen has accelerated since mid-October 2026 after Houthi ballistic missile and drone strikes hit Saudi airports in Riyadh and Dammam, plus energy infrastructure, killing civilians and prompting retaliatory coalition airstrikes on Houthi missile storage tunnels, launchers, and supply lines inside Yemen. The 2022 truce has collapsed amid Houthi territorial gains toward the Bab al-Mandab Strait and Saudi-backed counteroffensives by Yemeni government forces around Taiz and Marib. High-level talks in Tehran involving Saudi defense officials, Iran, Turkey, and Pakistan seek de-escalation channels, while the UN envoy has flagged risks of renewed full-scale fighting and proposed a two-month ceasefire that the coalition has welcomed. These recent cross-border exchanges and diplomatic moves shape near-term prospects for additional Saudi military operations.
