Yemen’s Houthi rebels are intensifying their push into the strategically vital Kahboub Mountains, a move that follows their rapid seizure of significant swaths of the Red Sea coast and could fundamentally alter the balance of power in the nation’s protracted civil war. This renewed offensive marks an end to the relative lull in hostilities that had persisted since 2022, drawing the conflict into the rugged highlands overlooking the Bab al-Mandeb strait, a critical global shipping artery.
The strategic importance of the Kahboub Mountains cannot be overstated, given their proximity to the Bab al-Mandeb strait. This chokepoint connects the Indian Ocean to the Red Sea and, crucially, the Suez Canal. As shipping through the Strait of Hormuz faces ongoing disruptions attributed to Iran, the Houthis’ primary ally, the significance of the Bab al-Mandeb route only escalates. Experts believe that controlling this elevated terrain would fortify the Houthis’ recently captured coastal positions and present a formidable challenge to any government counter-offensives.
Securing the Coastline: The Defensive Imperative of Kahboub
The primary objective for the Houthis in capturing the Kahboub Mountains appears to be the consolidation and defense of their gains along the Red Sea coast. While the mountainous terrain may not serve as a direct launchpad for attacks on maritime traffic, its control offers crucial defensive depth. This provides essential cover and protection for Houthi missile and drone operations in the Red Sea, making them more sustainable and harder for adversaries to disrupt.
Faozi Al-Goidi, a visiting fellow at the Middle East Council on Global Affairs, explains that the mountains act as a "natural wall" protecting the Houthis’ rear on the coast. He noted that controlling Kahboub would sever the coastal areas from the government-held south and exert direct pressure on Lahj governorate, with potential long-term implications for the port city of Aden. Without securing this high ground, Houthi forces stationed along the coast remain vulnerable to attacks from government-held territories to the south and east.
Ewa K Strzelecka, a visiting senior fellow at the London School of Economics, emphasizes the concept of "strategic resilience" that controlling the coastline, Mayyun Island, and the adjacent highlands would afford the Houthis. She posits that this consolidated control would create a significantly deeper and more defensible position around one of the world’s most critical maritime chokepoints. This strategic advantage would enable the Houthis to move personnel, weaponry, and supplies along the coast with reduced risk of their supply lines being severed from behind.
Andreas Krieg, a senior lecturer at King’s College London’s School of Security Studies, further elaborates on the surveillance and defensive capabilities provided by controlling the highlands. From these elevated positions, the Houthis can effectively monitor movements along the coast and towards the Bab al-Mandeb strait. Simultaneously, they can protect their missile, drone, and potential unmanned boat infrastructure located further inland.
The Battle for Kahboub: A Costly Highland Confrontation
The fighting for the Kahboub Mountains is proving to be a more arduous and slower-paced engagement compared to the Houthis’ swift advance across the coastal plains. Footage circulated on social media platforms, purportedly from the Taiz Military Axis Command’s media center, depicts intense combat between Yemeni government-aligned forces, local fighters, and Houthi rebels in the mountainous terrain. While this footage could not be independently verified, it underscores the ferocity of the current engagements.
Mohammed al-Basha, an analyst and former spokesperson for Yemen’s embassy in Washington, described the current battles as "not an easy battle." He highlighted that the fighting is occurring across some of Yemen’s most challenging landscapes, where control of even a single hilltop or mountain peak can come at a significant human cost. This rugged topography favors defensive stands and makes offensive operations exceptionally difficult for any attacking force.
Strategic Implications: Pressure on Taiz and Red Sea Dominance
The control of Kahboub could also significantly increase pressure on Taiz, a city of both symbolic and strategic importance. The Taiz governorate serves as a crucial bridge between the Houthi-controlled north, the government-held south, and the Red Sea coast. Whoever controls this region gains a considerable advantage in the movement of arms and supplies between the interior and the southern port of Aden. Consequently, losing Kahboub could represent a severe blow to the government’s strategic position.
Murad Al-Arefi, an editor at the Sana’a Center, suggests that taking Kahboub would "increase pressure on the southern and western approaches to Taiz." However, he cautions against interpreting this as immediate evidence of a broader attempt to encircle the city. The direct threat to the Taiz-Aden connection is less immediate, as Kahboub itself is not directly situated on that route.
Strzelecka points out that the crucial factor will be the Houthis’ ability to advance further east through Al-Wazi’iyah and towards the Al-Turbah-Lahj axis. Such a move would indeed place greater pressure on the southern approaches to Taiz and potentially weaken its vital connection with Aden. A sustained Houthi advance in this direction could force government forces to defend multiple mountain fronts simultaneously, relying on increasingly insecure routes for troop and supply movements. This would leave Taiz, one of Yemen’s largest population centers and a historical center of resistance against the Houthis, increasingly exposed.
The symbolic significance of a major Houthi breakthrough in Taiz, a city that endured a prolonged siege by the rebels after their seizure of Sana’a in 2014, would extend far beyond the territorial gains.
Red Sea Shipping: Escalating Concerns and Houthi Intentions
Officially, the Houthis have stated that any restrictions on shipping in the Bab al-Mandeb will be limited to vessels linked to Saudi Arabia. This declaration comes in the context of their broader campaign, ostensibly targeting shipping connected to Israel in response to the ongoing conflict in Gaza.
However, past Houthi operations in the Red Sea have seen them strike or endanger ships with no clear connection to their stated targets. This history raises significant questions about the precise application of any new maritime restrictions. By consolidating their control over the Kahboub Mountains, the Houthis would further solidify their position overlooking the Bab al-Mandeb, making it more difficult for opposing forces to dislodge them.
Simon Mabon, a professor of international relations at Lancaster University, views the current offensive as a clear demonstration of the Houthis leveraging their momentum to acquire more territory. He argues that their objective is to weaken their adversaries and "dominate Yemen further." Mabon concludes that "this is the Houthis trying to seize more ground and diminish the capacity of their enemies while increasing their strategic ability to close Bab al-Mandeb."
The implications for global trade and energy security remain a significant concern. The Bab al-Mandeb strait is one of the world’s busiest maritime routes, with a substantial portion of global trade and millions of barrels of oil passing through it daily. Any disruption or increased risk to shipping in this vital waterway has far-reaching economic consequences.
The renewed fighting and the strategic importance of the Kahboub Mountains underscore the ongoing complexities and high stakes of the conflict in Yemen. The Houthi pursuit of these strategic heights signals an ambition to consolidate gains, bolster defenses, and potentially exert greater leverage over regional maritime security. The international community continues to monitor these developments closely, aware of the potential for wider regional instability.
