Yemen’s Houthi forces are preparing to announce what they describe as a large-scale and significant military operation, with military spokesperson Brig. Gen. Yahya Saree signaling the disclosure for 4 PM local time. The announcement follows an escalation that began after a UN-mediated ceasefire, largely effective until mid-2026, broke down more frequently. The Iran-backed group, formally known as Ansar Allah, launched coordinated attacks in western Taiz and Hodeida’s Hayis district on September 4, 2026, and seized the strategic Red Sea port city of Mokha by September 10. Its forces later advanced to key islands in the Bab el-Mandeb Strait, through which roughly 12% of global trade passes daily, marking the group’s first major ground offensive in four years. Saudi-backed forces responded with airstrikes, but the Houthis retained Mokha and expanded their coastal footprint. The group says its military actions are defensive responses to Saudi actions and regional influence, while Iran supplies weapons technology, training and strategic guidance. The Houthis’ improved drone and missile capabilities have enabled attacks deeper into Saudi territory and more accurate strikes against maritime vessels. Previous attacks on commercial shipping in the Red Sea forced major companies to reroute vessels around the Cape of Good Hope, adding weeks and significant costs to Asia-Europe voyages. Saree’s May 6, 2026, Telegram announcement preceded the September offensive by nearly four months, suggesting previous announcements have been followed by military action.
