Houthis battle for Yemen's strategic heights as Trump reportedly halts strikes

The mountains around Kahboub have become the pivot point of Yemen's escalating conflict. Houthi fighters are pushing hard to seize these strategic heights in Taiz and Lahj provinces, terrain that overlooks both the Bab al-Mandeb Strait—one of the world's most critical shipping channels—and Mayyun Island in the Red Sea. Control of those peaks would allow the Iran-aligned group to cut off the government-held south from the coast, consolidating territorial gains they made this month when they seized the port of Mocha and the surrounding Red Sea littoral. The fighting on Monday was fierce and unrelenting, part of a broader escalation that has killed at least 674 people and forced more than 158,000 from their homes in just the past few weeks.

The immediate backdrop is a reported last-minute reversal by the Trump administration. According to The New York Times, the US had prepared air strikes against the Houthis for Sunday, responding to repeated pressure from Saudi Arabia's Crown Prince Mohammed bin Salman to join the fight. But Trump called off the attacks at the last minute, even as military personnel were loading ordnance onto aircraft. The decision reflects a calculation about American capacity and commitment: the US military is already stretched across multiple theaters in the region, munitions supplies are depleted, and adding another sustained military operation carries political and logistical costs the administration apparently decided to avoid. Jason Campbell, a senior fellow at the Middle East Institute, framed the dilemma plainly—Trump faced a choice between supporting a regional ally he is cultivating and taking on yet another difficult military commitment in a region where American forces are already heavily committed.

Houthi leader Abdel-Malik al-Houthi seized on the moment. In a public address, he accused the United States of considering direct military involvement alongside Saudi Arabia and warned Washington against escalation. He argued that the conflict would persist as long as the US objective remained dominance over Yemen. The rhetoric signals that the group sees the Trump reversal not as a permanent reprieve but as a tactical pause in a larger struggle for regional influence.

On the ground, the toll continues to mount. The World Health Organization documented 674 deaths and nearly 3,000 injuries since August 6, with particularly heavy casualties in the past week—164 deaths and 516 injuries between September 13 and 18 alone. Yemeni government forces claim they have struck Houthi positions and supply lines near the Bab al-Mandeb and in al-Bayda governorate, and that allied tribal fighters have retaken areas on Taiz's outskirts. The Houthis counter that Saudi Arabia conducted at least 157 air strikes across multiple provinces on Monday, killing at least one civilian in those operations and six more in a separate attack on Mocha late that evening, including two children. Neither side's battlefield claims could be independently verified.

The displacement is accelerating. Yemen's Executive Unit for the Management of Displaced Persons Camps reported that roughly 23,550 families—more than 158,000 people—have fled their homes across eight governorates this month alone, including Aden, Hodeidah, and Taiz. They are arriving at already overstretched camps with almost nothing. The World Food Programme's acting executive director, Carl Skau, described the situation starkly: tens of thousands of displaced people are pouring into facilities that cannot absorb them, and Yemen's food security is collapsing because the country imports 90 percent of its food. When ports and airports stop functioning due to fighting, that disruption cascades through the entire population. More than 18 million Yemenis—roughly half the country—already face acute food insecurity, a figure that will only worsen as the conflict deepens.

The UN has not stepped back from its diplomatic efforts. Hans Grundberg, the UN special envoy for Yemen, remains in contact with all parties to the conflict, and the office of UN Secretary-General António Guterres has warned that continued fighting risks further catastrophic damage to Yemen and its people. But the trajectory is clear: the fighting is intensifying, the humanitarian consequences are accelerating, and the international appetite for intervention—at least from Washington—appears to have limits.
