Yemen’s Southern Giants Brigades, alongside troops loyal to the internationally recognized government, launched a major offensive on October 5 against Houthi forces near the strategically vital Bab al-Mandeb strait. This operation is part of a broader nationwide military campaign aimed at reclaiming territories held by the Houthis, also known as Ansar Allah, including the crucial Red Sea coastline seized by the Iran-linked group in September.

The offensive marks a significant development in the protracted Yemeni conflict, representing one of the first major military gains for anti-Houthi forces in years. The operation's success highlights the effectiveness of a rare alliance between groups with differing political objectives, including those advocating for southern Yemen's independence, and national government forces.

By Monday afternoon, the pro-government forces, with the Giants Brigades playing a leading role, announced they had successfully severed the primary road connecting the Red Sea port city of Mocha to the Bab al-Mandeb strait. This strategic cut-off was announced shortly after Rashid al-Alimi, chairman of Yemen’s Presidential Leadership Council, declared a large-scale offensive against the Iran-backed Houthi movement.

The collaboration between the Southern Transitional Council-affiliated groups and national forces comes after a period of internal conflict in southern Yemen. In January, Saudi-aligned government forces clashed with the United Arab Emirates-backed STC, a confrontation that ultimately led to a relative consolidation of anti-Houthi military efforts.

The Giants Brigades, originating from the southern separatist movement, have emerged as a formidable military unit. Commanded by Abd al-Rahman Abu Zaraa al-Muharrami, a Salafi fighter, the brigade was largely formed by Salafi fighters during the intense battles for Aden in the first half of 2015. Their combat experience has positioned them as a key player in the ongoing conflict.

Credited with receiving arms, training, and funding from the UAE, the Giants Brigades gained prominence in 2017. During that year, they spearheaded an offensive that captured substantial territory along Yemen's western coast from Houthi control, with their advance eventually being halted at the outskirts of Hodeida, another key Red Sea port city.

The current offensive near Bab al-Mandeb is seen by analysts as a critical move to disrupt Houthi supply lines and territorial control in a region vital for global maritime trade. The strategic importance of the strait, a chokepoint for oil shipments, makes any gains there highly consequential.

Questions remain about the long-term sustainability of this broad anti-Houthi coalition and its ability to translate military successes into lasting political stability for Yemen. The differing agendas of the allied factions present a complex challenge for future governance and peace efforts in the war-torn nation.
