Reignition of the Tigray Civil War in Ethiopia: Analysis of Logistics and Air Supply Chain Risks in the Horn of Africa

Executive Summary

The Tigray People's Liberation Front (TPLF) has formed an anti-government alliance with six neighboring armed groups and officially declared a full-scale war, effectively nullifying the Pretoria Peace Agreement of 2022. The rebels have seized the airports in Mekelle, Shire, and Axum, leading Ethiopian Airlines to suspend all flights on those routes. As the rebel alliance expands its offensive into the Afar and Amhara regions, the long-term safety of the Djibouti-Ethiopia land corridor is also in doubt. Currently, Addis Ababa Bole International Airport and key logistics arteries are functioning normally, but localized conflicts are expected to persist for several months. Given that South Korean companies have a low dependence on direct routes to Tigray, the focus should be on continuous monitoring of Bole Airport and the Djibouti corridor, as well as securing alternative supply routes in advance.

I. Issue Situation Analysis

Reignition of the Tigray Civil War: Issue Situation Analysis

1. Background and Developments

The 2022 peace agreement between the Ethiopian federal government and the Tigray region was a temporary compromise that ended the civil war from 2020 to 2022, which is estimated to have resulted in up to 600,000 deaths[14]. Tensions between the federal government and the Tigray regional leadership have not been fully resolved even after the agreement[7]. This year, the conflict between the two sides has escalated again[7].

The Tigray People's Liberation Front (TPLF) was a faction that fought against the federal army during the previous civil war[4]. Recently, the TPLF has formed an anti-government alliance with six armed groups from neighboring regions[4]. This is not merely a local dispute but a multilateral armed coalition targeting the Addis Ababa federal government[4]. Just days after forming the alliance, the TPLF seized Mekelle Airport[4]. This is interpreted as a signal that former battlefield enemies have united against the Abiy Ahmed government[4].

2. Current Situation

The Tigray forces have seized not only Mekelle Airport but also other airports in Tigray that were under federal control[7]. They have expanded their offensive into the neighboring Afar and Amhara regions[7][11]. Getachew Reda, an advisor and minister to Prime Minister Abiy Ahmed, confirmed that Tigray fighters are controlling federal airports and have launched offensives in neighboring regions[7]. Both the federal government and the TPLF are blaming each other for initiating the offensive[7].

TPLF Vice Chairman Amanuel Assefa stated in an interview with AFP, "We are now in a full-scale war situation"[10]. The Tigray rebels officially declared a state of full-scale war against the federal government on Thursday[12]. This declaration effectively nullifies the 2022 peace agreement[12]. The rebels are mobilizing forces aimed at the ousting of the federal prime minister[12].

In the Afar region, federal forces engaged in overnight clashes to repel rebel attacks[11]. Reports have also emerged of internet blackouts across northern Ethiopia[11]. Online monitoring organization NetBlocks confirmed these communication blackouts[14]. Local residents are concerned that the communication blackouts and supply blockades imposed during the 2020-2022 civil war may be repeated[14][11].

Ethiopian Airlines has suspended flights to Mekelle, Shire, and Axum[1]. The airline stated on social media that this was due to the "current situation in the Tigray region," but did not provide specific explanations[1]. According to two local sources confirmed by Reuters, Tigray forces seized control of Mekelle Airport from federal police overnight[1]. Ethiopian military authorities announced that they had killed hundreds of TPLF rebels[10]. This suggests that the intensity of the fighting has already reached a significant level[10].

3. Key Actors and Positions

Federal Government (Prime Minister Abiy Ahmed)defines the offensive by the armed alliance, including the TPLF, as a challenge to national unity[7]. While confirming the rebels' seizure of airports and offensives in neighboring regions through Getachew Reda, they claim that federal forces have repelled rebel attacks in the Afar region[7][11]. Military authorities emphasize their military superiority by disclosing the scale of rebel casualties[10].

TPLF and the Anti-Government Alliancehave effectively nullified the 2022 peace agreement and set the goal of overthrowing the federal government[12]. Vice Chairman Amanuel Assefa's statement about "full-scale war" indicates that this alliance has shifted its focus from limited regional conflicts to a comprehensive armed struggle aimed at regime change[10]. The formation of an alliance with six neighboring armed groups is seen as a strategy to reshape the confrontation dynamics from the previous civil war and expand the anti-federal front[4].

UAEstrongly condemned the offensive, airport seizures, and military actions of the TPLF and the anti-government alliance[16]. Sheikh Shakhbout called for an immediate cessation of hostilities and protection of civilians[16]. This stance by the UAE seems to stem from the belief that stability in the Horn of Africa is directly linked to the Gulf countries' interests in the Red Sea and air logistics[16].

Ethiopian Airlines, representing the civil aviation and logistics sector, has immediately suspended flights on Tigray routes due to safety concerns[1]. This is a practical response that excludes political interpretations but is seen as a signal of the broader impact on the regional air network centered around Addis Ababa[1].represented by Ethiopian Airlines, has immediately suspended flights to Tigray routes due to safety concerns[1]. This is a practical response that excludes political interpretations but is seen as a signal of the broader impact on the regional air network centered around Addis Ababa[1].

4. Key Issues

The first issue is whether the 2022 peace agreement has effectively collapsed. While the TPLF has already declared "full-scale war," the federal government has not yet formalized the nullification of the agreement[10][12]. The second issue is the extent of the escalation into the Afar and Amhara regions. As the rebels' offensive spreads beyond Tigray's borders into neighboring states, the potential for the conflict to escalate into a multilateral regional war is increasing[7][11]. The third issue is whether the communication and logistics blockades will lead to a humanitarian crisis. Concerns about the recurrence of communication blackouts and blockades experienced during the 2020-2022 civil war are already spreading among local residents[14].

II. In-Depth Analysis of the Issue

Reignition of the Tigray Civil War: In-Depth Analysis of the Issue

1. Analysis of Root Causes

The 2022 Pretoria Peace Agreement succeeded in ending hostilities but did not address the political roots of the conflict. The agreement stipulated the disarmament of the TPLF and the re-entry of federal forces into Tigray. However, issues regarding the political status of the Tigray region, the return of western Tigray territory, and the withdrawal of Eritrean troops remain unresolved. The renewed tensions between the federal government and the Tigray regional leadership this year stem from this unfinished agreement structure[7].

Vice Chairman Amanuel Assefa's characterization of the situation as a "full-scale war" suggests that the nullification of the agreement is not an accidental clash but an explosion of accumulated distrust[10]. The Tigray rebels' official declaration of full-scale war on Thursday indicates that their goal is not merely to expand regional autonomy but to oust the federal prime minister[12]. This signals that the Tigray leadership has abandoned any possibility of coexistence with the Abiy Ahmed government. The mutual blame for initiating preemptive attacks between the federal government and the TPLF[7] demonstrates that both sides believe they have nothing left to gain within the framework of the agreement.

More fundamentally, the structural vulnerability of Ethiopia's federal system is at play. Ethiopia has adopted an ethnic-based federalism, where regional governments have traditionally maintained independent armed forces. The Abiy Ahmed government’s push for centralized integration has provoked resistance from regional elites, including those in Tigray, which is a structurally embedded variable.

2. Structural Context

Political StructureThe most significant change determining the nature of this situation is the TPLF's formation of an anti-government alliance with six neighboring armed groups[4]. This means that forces that previously fought on the side of the federal army during the civil war have now united against the Abiy Ahmed government[4]. The shift from a Tigray-only regional rebellion to a multilateral armed coalition indicates that the Abiy Ahmed government is facing a legitimacy crisis not only regarding Tigray but also on multiple fronts, including Amhara and Afar. In fact, the rebels expanded their offensive into the Afar and Amhara regions immediately after forming the alliance[7][11].

Security StructureFederal forces engaged in overnight clashes to repel rebel offensives in the Afar region[11], and military authorities announced that they had killed hundreds of TPLF rebels[10]. This indicates that the fighting is already proceeding with considerable military intensity. At the same time, internet blackouts have been confirmed across northern Ethiopia[14][11], raising the possibility that the federal government has reactivated information control and blockade tactics similar to those used during the previous civil war. Communication blackouts and supply blockades were key factors in the humanitarian disaster during the 2020-2022 civil war. Local residents' concerns about the recurrence of this pattern[14][11] are based on direct experience rather than unfounded fears.

Economic and Logistics StructureThe suspension of Ethiopian Airlines' flights to Mekelle, Shire, and Axum[1] reveals vulnerabilities not just in safety measures but in the very air connectivity of the Horn of Africa. Ethiopian Airlines has been a key player in regional logistics and passenger transport centered around the Addis Ababa hub. If the suspension of flights on Tigray routes becomes prolonged, the region will face a dual disruption of land blockade and air isolation. This is essentially the same humanitarian crisis structure that Tigray experienced during the 2020-2022 civil war.

3. Historical Precedents and Comparative Cases

The Tigray civil war from 2020 to 2022 itself serves as the most direct precedent. That civil war is estimated to have resulted in over 6 million deaths, with communication blackouts and supply blockades being key mechanisms that maximized civilian casualties[14]. The initial phase of the current situation, where the federal government and the TPLF are both claiming preemptive attacks, is structurally similar to the situation just before the outbreak in November 2020. However, a decisive difference is that while Tigray was a singular isolated front at that time, this time a multi-front has formed through alliances with six armed groups[4].

The Ethiopian case also has points of comparison with the recent analysis by EAI on the reignition structure of the Yemen civil war. In Yemen, a UN-mediated ceasefire in 2022 maintained a low-intensity standoff until external variables (the Israel-Iran war) intervened and caused its collapse[3][6]. In contrast, the Tigray case reached the collapse of the agreement solely due to internal political dynamics without external shocks. This suggests that the Pretoria Agreement was built on a more fragile foundation than the Yemen ceasefire. Both cases share the commonality that the seizure of logistics hubs, such as airports, served as symbolic triggers for the reignition of conflict[1][2]. In Yemen, the struggle over Sana'a Airport became the catalyst for full-scale confrontation[2], while in Ethiopia, the seizure of Mekelle Airport played the same role[1].

Additionally, as seen in the Algeria-UAE severance of diplomatic ties[9], perceptions of intervention by regional powers often amplify conflicts in the Africa-Middle East region. In the Ethiopian situation, the UAE's strong condemnation of the TPLF's offensive and calls for an immediate cessation of hostilities[16] demonstrate that Gulf countries view stability in the Horn of Africa as an extension of their own security and economic interests.

4. Key Variables Shaping the Development of the Issue

The first variable is the cohesion of the armed alliance. The extent to which the six groups allied with the TPLF can sustain military cooperation will determine the geographical spread of the conflict. Whether the expansion of offensives into Afar and Amhara[7][11] is a temporary disruption or a sustainable multi-front strategy remains unclear.

The second variable is the response capability of the federal forces. The scale of rebel casualties announced by military authorities[10] suggests that the federal army maintains significant firepower superiority, but whether it can sustain a long-term war on multiple fronts is a separate issue.

The third variable is the duration of communication and logistics blockades. Whether the internet blackout[14][11] is a temporary measure or leads to long-term blockades like those during 2020-2022 will influence the humanitarian situation and the timeline for normalizing air and logistics.

The fourth variable is the level of intervention by external actors. Whether the UAE's call for a cessation of hostilities[16] leads to substantial mediation pressure or remains at the level of statements will serve as a benchmark for gauging future international involvement.
