Houthis seek expansion after reaching Bab al-Mandab

The Iran-backed Houthi rebels have recently expanded their control in Yemen, seizing key territories along the southwestern coastline and reaching the Bab al-Mandab Strait, a strategically crucial maritime chokepoint. This expansion took place between September 9 and 17, 2026, following a campaign that began on August 9. The Houthi forces' rapid advances, advancing a total of 120 kilometers within two days, were facilitated by factors such as intelligence penetration, poor coordination, inadequate leadership, and insufficient air support.

The recent gains have bolstered the Houthi military's mobilisation capacity and morale, heightening pressure on Yemen's government defenses and challenging the perceived cohesion and effectiveness of the Yemeni Armed Forces. Iran, which has long sought control over the Bab al-Mandab Strait, views these gains as a "victory" and a "divine triumph".

The strategic salient formed by the Houthi advances remains unconsolidated, necessitating further commitment, fortification, and the implementation of defensive measures to secure these territories. The Houthis are now intensifying attacks into Saudi Arabia in an effort to redraw the rules of the game in the region.
