**The operation began on Oct. 29, and Houthi forces did not capture Aden or Perim Island.**

Saudi Arabia began a new military operation in Yemen on Oct. 29. The campaign targeted Houthi positions across the country. In the days that followed, Houthi forces did not succeed in taking the southern port city of Aden. They also failed to capture the strategic Island of Perim.

It involved the deployment of Saudi armed units in the conflict. The action represented a notable escalation in the ongoing hostilities.

Houthi troops attempted to move toward Aden after the Saudi offensive. By Oct. 31 they had not entered the city. The port remained under the control of Yemeni government forces.

The Houthis also sought to seize Perim Island during the same period. By Oct. 31 the Island was still not under Houthi control. Its strategic position in the Bab al-Mandab strait remained unchanged.

## Analysis

The Saudi-led operation on Oct. 29 adds a new phase to the Yemeni conflict, increasing the intensity of direct involvement by a regional power. By opening a fresh front, Saudi Arabia may aim to pressure the Houthi movement and alter the balance of forces on the ground. The escalation could also raise concerns about civilian harm and widen the humanitarian crisis that has persisted for years.

The failure of Houthi forces to take Aden and Perim Island suggests limits to their offensive capacity despite the Saudi escalation. Control of Aden would have given the Houthis a major southern foothold, while Perim Island holds strategic value for maritime traffic through the Bab al-Mandab. Their inability to secure either location may weaken the Houthis' bargaining position in any future negotiations.

Looking ahead, the conflict's trajectory remains uncertain. Saudi Arabia may continue its military pressure, but the lack of Houthi gains could lead to a recalibration of tactics on both sides. Regional actors and humanitarian agencies will watch closely to see whether the stalemate persists or if new developments shift the dynamics of the war.
