Ethiopia's Tigray Conflict Resumes, Threatening Horn of Africa Stability

Nearly four years after the 2022 Pretoria Agreement ended one of the deadliest wars of the 21st century, fighting has reignited in northern Ethiopia. Tigrayan forces under the TPLF seized airports in Mekelle, Axum, and Shire in late September 2026, launched offensives into Afar and Amhara regions, and formed a tactical alliance with groups including Amhara Fano militias—former adversaries—to challenge Prime Minister Abiy Ahmed’s federal government. Ethiopian forces responded with drone strikes and counteroffensives, suspending flights and disrupting services, while civilians stockpiled supplies amid fears of renewed blockades.[1][2]

The Pretoria deal’s incomplete implementation—partial disarmament, unresolved territorial disputes (including Eritrean occupation of parts of Tigray and Amhara claims on Western Tigray), and the TPLF’s reassertion of power—set the stage. A hardline TPLF faction consolidated control, leading to lower-level clashes near the Sudanese border by August 2026 and an August-September escalation. The new Ethiopian Peoples’ Forces Alliance for Survival unites seven armed groups against Addis Ababa, marking a striking shift where former enemies coordinate against a common foe.[3][4]

Eritrea’s role adds volatility. Relations with Ethiopia have deteriorated since 2023 over Abiy’s emphasis on Red Sea access, particularly the Eritrean port of Assab. Addis Ababa accuses Asmara of backing the TPLF alliance; Eritrea denies it, but the strategic incentive for Asmara—a distracted Ethiopia—aligns with historical enmity and recent border tensions. Sudan’s civil war further complicates matters, with external actors (UAE, Egypt, Israel) focused on Red Sea ports and Horn geography, raising risks of spillover or proxy involvement.[5]

International Crisis Group warns of a multi-front offensive risking wider war, while experts note Gulf rivalries and Ethiopia’s internal ethnic fractures could transform a domestic conflict into regional instability. The 2020-2022 war’s estimated 600,000 deaths, mass displacement, and atrocities underscore the stakes; current fighting, though concentrated in the north, threatens to unravel fragile ceasefires and draw in neighbors. Mediation efforts by the AU and others face hurdles from incomplete prior agreements and shifting alliances.[6]

Deeper connections reveal how unresolved power struggles, Red Sea ambitions, and cross-border insurgencies create a volatile nexus with implications for global trade routes and African security architecture.
