Key Global Conflict Zones in 2026: Escalation Risks Loom

Conflicts around the world are poised for potential escalation in 2026, with significant developments occurring in regions like Yemen, South Sudan, and Mozambique. The dynamics in these areas are shifting rapidly, raising concerns about renewed violence and instability.

Yemen: A Sudden Territorial Shift

In Yemen, the ongoing civil war faces a new chapter following a sudden offensive by the Southern Transitional Council (STC) on December 2, 2025. This group, supported by the United Arab Emirates, launched a well-coordinated attack that swiftly overtook forces loyal to the Saudi-backed Presidential Leadership Council (PLC). Observers noted that the PLC’s troops offered minimal resistance, leading some to speculate about a prior agreement between factions.

The STC’s offensive resulted in the capture of the Hadramawt and al Mahra regions, which together account for nearly half of Yemen’s landmass, although they are home to only about 5% of the population. This territorial gain is significant, as the STC now controls approximately 80% of Yemen’s oil reserves, intensifying tensions within the anti-Houthi coalition, primarily between Saudi Arabia and the UAE. The Saudi government reacted strongly, demanding the STC withdrawal from the newly seized territories, but the STC rejected this demand, prompting airstrikes from Saudi forces.

As Saudi Arabia amassed thousands of troops on its border in response, the possibility of a renewed civil war looms. The situation is further complicated by the involvement of the Houthi movement, which may exploit any fractures within the anti-Houthi coalition.

South Sudan: A Nation on the Brink

In South Sudan, the backdrop of political power struggles between President Salva Kiir and First Vice President Riek Machar threatens to plunge the nation back into civil war. Although the civil war officially ended in 2018 with the signing of the Revitalized Agreement, tensions have resurfaced in 2025, particularly following Machar’s arrest in March.

The United Nations Mission in South Sudan reported alarming levels of violence, with 635 civilian deaths and hundreds of thousands displaced during the year. Nick Haysom, the U.N. Secretary General’s special representative for South Sudan, indicated that the political conflict has become more pronounced, diverging from previous intercommunal disputes. The upcoming elections scheduled for December 2026 may further complicate the situation, as observers caution that their execution could exacerbate tensions rather than alleviate them.

Mozambique: Resurgence of Insurgency

The insurgency led by the Islamic State-Mozambique (IS-M) has escalated significantly in Cabo Delgado province. Since its inception in 2017, this group has capitalized on the region’s instability, leading to a humanitarian crisis marked by over 350,000 displaced individuals. In November 2025 alone, more than 100,000 people were forced to flee due to violent clashes.

In 2025, IS-M was responsible for 549 deaths in 302 recorded attacks, representing a 56% increase from the previous year. The insurgency’s resurgence has been fueled by the waning effectiveness of the Rwanda Defense Force, which had previously helped push back IS-M forces. Researcher Tomás Queface noted that Rwandan troops are now less active in the conflict, which may embolden IS-M and lead to an expansion of their influence.

The stability of the Mozambican government under President Daniel Chapo is precarious, having assumed office after a contested election in January 2025. The fragile legitimacy of his administration, coupled with IS-M’s growing capabilities, presents a dire forecast for the region.

The circumstances in Yemen, South Sudan, and Mozambique underscore the precarious state of global peace heading into 2026. As these conflicts evolve, the international community remains watchful, aware that the potential for escalation could have far-reaching implications.
