Yemen’s fragile lull unravels as rival tribal mobilizations raise risk of renewed war
Tribal forces aligned with both Yemen’s Sanaa-based authorities and the Aden government are mobilizing toward northern fronts, with reports of fresh clashes after years of relative low-intensity conflict. The movements suggest the country may be sliding back toward large-scale war, putting millions of civilians in the line of fire again.
Yemen’s uneasy pause is starting to look like a prelude rather than a peace. After more than four years of relatively low‑intensity fighting following the expiration of a formal ceasefire, tribal forces on both sides of the country’s divide are mobilizing toward key front lines, raising the risk that one of the world’s worst humanitarian crises could again be fueled by large‑scale war.
In recent days, tribes allied with the Sanaa-based authorities, dominated by Ansarallah (often referred to as the Houthis), have announced a general mobilization to counter what they describe as a serious impending offensive by the internationally recognized, Aden-based government. It would be the first major offensive attempt by Aden-aligned forces since 2022. At the same time, tribes from the governorates of Jawf, Marib and Hadramaut, aligned with Aden and its backers, have signaled a significant build-up of their own forces toward northern fronts, where sporadic clashes have already been reported.
For ordinary Yemenis, these movements are ominous. Communities in Marib and Jawf still bear the scars of earlier battles that displaced families multiple times, destroyed farms and cut access to water and fuel. A new round of full-scale fighting would likely trigger fresh waves of displacement from already strained camps and urban peripheries, at a time when international aid budgets are shrinking and basic services like healthcare and electricity remain threadbare.
Operationally, the mobilizations show that both camps have been using the relative lull since the April 2, 2022, ceasefire to regroup rather than to reconcile. Although the truce formally ended in October of that year, major combat gave way to a patchwork of local deals and low‑level skirmishes. The conflict focus shifted to competition within the Saudi- and Emirati-backed sphere of influence in the south and east, with Riyadh and Abu Dhabi backing different factions in Aden, Shabwa and Hadramaut. Now, as those rivalries grind on, the front against Ansarallah in the north is being re-energized rather than wound down.
Strategically, a return to broader war would test the recalibrated roles of Saudi Arabia and the United Arab Emirates. Both have edged away from direct front-line engagement in recent years, favoring talks with Sanaa and rebalancing toward their domestic priorities and regional diplomacy. If Aden-aligned tribal forces push north in earnest and Sanaa’s allies respond in kind, Riyadh and Abu Dhabi will face hard decisions about how much to re‑invest militarily, financially, or politically in a conflict that has already cost them heavily.
The mobilizations also intersect with Yemen’s growing importance in maritime security. Since 2023, the Red Sea and Bab el-Mandeb have seen repeated attacks on shipping linked to Israel and its partners, often attributed to Ansarallah forces in western Yemen. A wider ground war in the north and center of the country would complicate any efforts to stabilize the coast or negotiate maritime arrangements, potentially exposing more civilians in coastal areas to airstrikes and retaliation.
A memorable way to understand Yemen’s predicament is that the country has been living in a ceasefire’s shadow without its protections. The guns never fully fell silent, but aid flows and diplomacy assumed they might one day. New tribal mobilizations suggest that hope is fading, replaced by calculations about territory, leverage and future bargaining power.
What to watch now are concrete indicators that posturing is turning into a campaign: sustained clashes rather than sporadic skirmishes along northern fronts; significant redeployments of heavy weapons, armor or air assets; and renewed cross-border fire between Ansarallah forces and Saudi Arabia. Diplomatic tracks—whether through U.N. channels, Omani mediation or direct Saudi‑Ansarallah contacts—will show whether regional powers are prepared to lean in to stop a slide back into full-scale war or are bracing to manage its fallout instead.
