Yemen's fracturing front: Saudi-Emirati rivalry risks a deeper quagmire

Yemen's civil war, now in its 11th year, has taken a perilous turn. What began as a Saudi-led coalition against the Iran-backed Houthis in 2015 has devolved into infighting among allies. Tensions between Saudi Arabia and the United Arab Emirates (UAE) have boiled over in the eastern province of Hadramout, raising fears of a model akin to Sudan's Rapid Support Forces (RSF)—paramilitaries allegedly backed by Abu Dhabi, operating outside state control and accused of atrocities. As of January 3rd 2026, clashes continue, with Saudi-backed forces advancing on positions held by the UAE-supported Southern Transitional Council (STC), an avowedly separatist group. This rift not only threatens Yemen's fragile unity but also exposes cracks in Gulf alliances, with implications rippling across the Middle East.

The roots of discord

The headline-grabbing escalation traces back to late 2025, when an article in Al-Akhbar, a Lebanese newspaper often critical of Gulf monarchies, warned of the UAE cultivating parallel armed groups in Yemen, mirroring its purported role in Sudan. There, the RSF—denied by the UAE but flagged by UN experts—has clashed with the national army, destabilising the country. In Yemen, critics see parallels in the STC and its affiliates, such as the Hadrami Elite Forces, which are perceived as loyal to Emirati interests rather than the internationally recognised government.

Saudi Arabia, bordering Yemen to the north, prioritises a unified state to safeguard its security and counter Iranian influence via the Houthis. Hadramout, with its vast oil reserves—accounting for much of Yemen's dwindling energy exports—and proximity to the kingdom, is a strategic red line. The UAE, by contrast, champions southern independence, viewing the STC as a bulwark against Islamist factions like Islah (affiliated with the Muslim Brotherhood) and a means to secure maritime routes in the Arabian Sea and Gulf of Aden.

Key events unfolded rapidly. In early December 2025, STC forces launched a surprise offensive, capturing swathes of Hadramout and al-Mahra provinces, including vital oil fields, ports and border crossings. Riyadh demanded withdrawal, followed by initial airstrikes. By mid-December, Saudi-led coalition jets targeted a suspected UAE weapons shipment at Mukalla port in Hadramout. Abu Dhabi denied involvement and announced a full withdrawal of its remaining troops, but suspicions lingered. On January 1st-2nd 2026, partial STC redeployments allowed Saudi-aligned "Homeland Shield" forces to enter contested areas, yet heavy fighting erupted anew. Saudi advances recaptured key bases, like the 37th Brigade camp, with airstrikes claiming 7-20 STC lives, per varying reports. The STC, undeterred, accused Riyadh of aggression and vowed resistance, while unveiling plans for a southern constitution and a two-year referendum on independence.

This mirrors broader frictions: in Sudan, Saudi Arabia backs the army against the UAE-linked RSF; in Yemen, past clashes, such as the 2019 battle for Aden, hinted at the divide. The anti-Houthi coalition, once a symbol of Gulf solidarity, now appears irreparably strained.

Implications for Yemen and beyond

The crisis's ramifications are profound and multilayered. For Yemen, already gripped by one of the world's gravest humanitarian disasters—with over 21 million in need of aid—the fighting exacerbates fragmentation. The STC's separatist agenda could cement a de facto partition, reviving the pre-1990 divide between north and south. This undermines the Presidential Leadership Council (PLC), the nominal government, and complicates UN-brokered peace talks with the Houthis, who control Sana'a and much of the north. The rebels, adhering to a tenuous truce, have stayed sidelined but could exploit the chaos to expand, perhaps resuming drone strikes on Saudi targets or disruptions in the Red Sea shipping lanes.

Security vacuums invite opportunists. Al-Qaeda in the Arabian Peninsula (AQAP), once suppressed by coalition efforts, may regroup amid the disarray. Civilian tolls mount: clashes in oil-rich zones risk infrastructure damage, halting exports and deepening famine. Yemeni voices decry foreign meddling, with locals lamenting "Yemeni blood spilled for Gulf agendas." Hadramout's governor has spearheaded operations to reclaim sites, but entrenched STC positions suggest protracted conflict.

On the Gulf stage, the feud strains the Cooperation Council (GCC). Saudi Arabia and the UAE share stakes in OPEC stability and anti-Iran postures, yet compete for regional hegemony—from Libyan proxies to Sudanese influence. Riyadh's Vision 2030 economic reforms could suffer from heightened border costs and refugee influxes, while Abu Dhabi's Red Sea ambitions falter without STC leverage. Economic fallout includes potential oil price volatility from disrupted Hadramout fields.

Regionally, Iran gains indirectly: Houthi empowerment bolsters Tehran's proxy network. Broader Middle Eastern stability wobbles, with U.S.-mediated efforts in Sudan and elsewhere complicated. Global concerns loom—navigation disruptions in the Arabian Sea could spike energy costs, while weakened counter-terrorism lets extremists thrive. International actors, including the UN and Oman (a neutral mediator), call for restraint, but without compromise, the rift invites external powers like China or Russia to fill voids.

Horizon: A precarious path ahead

As of January 3rd, the situation simmers uneasily. Short-term prospects hinge on diplomacy: Saudi invitations for Riyadh talks and Omani intercession could yield a ceasefire, with UN Security Council debates in January adding pressure. Direct Saudi-UAE confrontation seems improbable—mutual interests against Iran act as a brake—but missteps, like errant airstrikes, could ignite escalation. Fighting persists in Hadramout, with Saudi gains offset by STC reinforcements.

In the medium term, failed negotiations might solidify southern autonomy, birthing a frozen conflict or outright division. Covert UAE support for proxies could endure, intensifying rivalry and tempting Houthi intervention. Economic strains may force de-escalation, yet the STC's referendum push signals entrenchment.

Longer-term, Yemen risks irreversible balkanisation, prolonging war and hobbling the anti-Houthi cause. A full Saudi-Emirati reconciliation in 2026 appears doubtful, potentially reshaping Gulf pacts and drawing in superpowers. Optimists eye federalism as a salve—granting southern devolution within unity—but history's scars, from unification's 1994 civil war to today's proxy battles, augur caution. Yemen's tragedy endures, a pawn in larger games, with no swift resolution in sight.

The Core Fault Lines

Actor	Primary Interest	How It Plays Out in Yemen
Saudi Arabia	Preserve a friendly, Sunni‑aligned government on its southern border; contain Iranian influence.	Leads the coalition, supplies air power and financing, but increasingly wary of the cost and the coalition’s diminishing returns.
United Arab Emirates (UAE)	Project power in the Red Sea and Horn of Africa, secure maritime routes, and protect commercial interests (e.g., ports in Aden, Socotra).	Backed the Rapid Support Forces (RSF)‑linked militias and Southern Yemeni factions; pursued a more hands‑on, ground‑based strategy.
Southern Transitional Council (STC) (UAE‑aligned)	Secessionist agenda for an independent South Yemen.	Controls Aden and parts of the south; often clashes with the internationally‑recognised government backed by Riyadh.
Houthis (Ansar Allah)	Maintain control of the north and leverage anti‑Saudi sentiment.	The primary adversary of the coalition; their resilience forces the coalition to keep committing resources.

The Saudi‑UAE partnership that once appeared seamless now suffers from divergent strategic priorities:

• Saudi Arabia wants a stable, unified Yemen that can act as a buffer.
• UAE seeks regional footholds (ports, fisheries, anti‑piracy bases) and is comfortable supporting fragmented, locally‑controlled authorities

Potential Trajectories

What “Irreparably Strained” Looks Like

·       Funding Gaps – Saudi Arabia has begun scaling back cash flows for coalition air operations, while the UAE continues to fund ground logistics for the STC. The asymmetry erodes joint planning.

·       Diplomatic Channels – Regular coordination meetings in Riyadh have become sporadic; the two capitals now often communicate through third‑party mediators (e.g., Oman, Egypt) rather than directly.

·       Narrative Divergence – Saudi media frames the coalition as a counter‑terrorism mission, whereas UAE outlets emphasize maritime security and humanitarian aid in the south. The lack of a unified story weakens the coalition’s legitimacy.

·       Strategic Realignment – Both Gulf states are pivoting: Saudi Arabia looks toward a Saudi‑UAE détente with Israel and a broader “Middle East peace” agenda, while the UAE deepens ties with African port states (Somalia, Eritrea) that benefit from a fragmented Yemen.
