Houthi (Ansarullah) forces have significantly expanded their control over Yemen’s Red Sea coastline, capturing the port of Mocha, the Dhubab district, and several key islands, including Mayun (Perim) and the Hanish islands. This offensive has consolidated their grip on the Bab al-Mandab Strait, a critical maritime chokepoint for global trade and energy shipments.

In response, government forces, supported by Saudi-led coalition airstrikes, have launched counter-offensives. While government troops have reclaimed strategic high-ground positions in western Taiz, including areas in the Ash-Shamayatayn and Dhubab districts, fighting remains intense. Saudi Arabia has reportedly conducted dozens of airstrikes across Taiz, Lahj, and Al-Jawf provinces. The Houthi group has also escalated attacks against Saudi Arabian territory, claiming to have targeted the King Khalid airbase in Khamis Mushait with ballistic missiles and drones. This regional escalation has contributed to volatility in global energy markets, with Brent crude prices rising above $107 per barrel.

The maritime situation has drawn international concern. Reports from the Israeli newspaper Yedioth Ahronoth indicate that intense Yemeni attacks have placed the Israeli security establishment on high alert. Analysts have noted that the narrow Bab al-Mandab Strait is highly susceptible to effective blockades, and the Israeli military views these Red Sea developments as a profound shift that could extend influence toward the Mediterranean Sea.

The humanitarian situation continues to deteriorate. The International Organization for Migration reports that tens of thousands of people have been newly displaced since early September, with many fleeing toward Djibouti.
