Sahel Security Crisis: West Africa Instability & Conflict Tracker

Overview

The Sahel - a semi-arid belt stretching across Africa south of the Sahara - has become one of the world's most volatile security environments. The region encompasses parts of Mali, Burkina Faso, Niger, Chad, Nigeria, and Mauritania, and faces an extraordinary convergence of military coups, jihadist insurgencies, ethnic violence, and great-power competition.

Since 2020, military juntas have seized power in Mali (2020, 2021), Burkina Faso (2022), Niger (2023), and Chad (transitional military rule since 2021). These governments have expelled French forces, withdrawn from the Economic Community of West African States (ECOWAS), and formed the Alliance of Sahel States (AES), a mutual defense pact that signals a fundamental realignment of security partnerships in West Africa.

The crisis carries global implications: the Sahel serves as a transit corridor for migration to Europe, a theater for Russian and Chinese influence expansion, and a testing ground for jihadist organizations seeking to establish permanent territorial control. AFRICOM and European partners are recalibrating their counterterrorism strategies as traditional access agreements collapse.

Military Coups & Political Instability

The wave of military coups across the Sahel represents the most significant political upheaval in the region since independence. Mali's August 2020 coup, led by Colonel Assimi Goita, was followed by a second takeover in May 2021 when Goita deposed the transitional civilian leadership. Burkina Faso experienced two coups in 2022 alone, with Captain Ibrahim Traore ultimately consolidating power. Niger's July 2023 coup ousted President Mohamed Bazoum, who had been one of the West's closest partners in the region.

These juntas share common justifications: the failure of democratic governments to address security threats, popular frustration with French military presence, and promises to restore sovereignty. In practice, the coup governments have suspended constitutions, delayed promised elections, and restricted press freedoms. The formation of the AES in September 2023 - and the collective withdrawal from ECOWAS in January 2024 - signals these governments intend to chart an independent course rather than return to pre-coup institutional frameworks.

The political instability has complicated international counterterrorism cooperation. UN peacekeeping missions have been expelled from Mali, bilateral security agreements with France and the EU have been terminated, and diplomatic channels that previously facilitated intelligence sharing have been severed. The resulting security vacuum has been partially filled by Russian mercenary forces.

Jihadist Insurgency (JNIM/ISWAP)

Two major jihadist organizations dominate the Sahel's insurgent environment. Jama'at Nusrat al-Islam wal-Muslimin (JNIM), affiliated with al-Qaeda, operates primarily across Mali, Burkina Faso, and Niger. The Islamic State West Africa Province (ISWAP) and its Sahel branch, Islamic State Sahel Province (ISSP), control territory in the Lake Chad Basin and increasingly in northern Mali and Niger. These groups are rivals but collectively control more territory than at any point since the 2012 Mali crisis.

JNIM has proven particularly adaptive, combining guerrilla attacks on military installations with governance strategies that provide basic services and arbitration in areas under its control. The group has expanded southward into coastal West African states including Togo, Benin, and northern Ghana, raising fears of a jihadist corridor reaching the Gulf of Guinea. ISWAP, while smaller in the Sahel proper, has demonstrated greater lethality per attack and has targeted both government forces and JNIM fighters in a violent competition for supremacy.

The departure of French and UN forces has not been offset by increased capacity among national armies or Russian mercenaries. Multiple assessments indicate that jihadist territorial control and attack frequency have increased since the coups, particularly in rural areas of central Mali, northern Burkina Faso, and the tri-border region where Mali, Niger, and Burkina Faso converge. Civilian casualties from both insurgent attacks and military counteroffensives have reached record levels.

Wagner/Africa Corps Presence

Russia's Wagner Group - rebranded as Africa Corps following the death of Yevgeny Prigozhin in August 2023 - has become the primary external security partner for Sahel junta governments. Mali was the first to invite Wagner forces in late 2021, followed by Burkina Faso and Niger. These mercenary deployments typically involve between 1,000 and 2,000 personnel per country, providing presidential guard services, counterinsurgency support, and training for national forces.

The Wagner/Africa Corps model exchanges security services for access to natural resources, including gold mining concessions, and diplomatic support at the UN Security Council. In Mali, Wagner forces have been implicated in multiple mass atrocity incidents, including the March 2022 Moura massacre where an estimated 300 civilians were killed during a military operation. Human rights organizations have documented patterns of extrajudicial killings, arbitrary detention, and collective punishment in areas where Wagner operates alongside national armies.

Following Prigozhin's death, the Russian Ministry of Defense moved to consolidate control over Africa operations through the Africa Corps structure. This transition has been uneven, with some personnel remaining loyal to Wagner's corporate successor while others have been integrated into the formal Russian military chain of command. For Sahel governments, the rebranding has had little practical impact - Russian security assistance continues to flow, and the mercenary presence provides both military capability and political insurance against Western pressure for democratic transitions.

French Withdrawal & Western Response

France's withdrawal from the Sahel marks the end of a decade-long military engagement that began with Operation Serval in 2013 and expanded into the broader Operation Barkhane across five Sahel nations. At its peak, Barkhane deployed approximately 5,100 French troops with bases in Mali, Niger, Burkina Faso, and Chad. By 2024, France had been expelled from Mali, Burkina Faso, and Niger, retaining only a reduced presence in Chad - which was itself terminated in late 2024 when Chad ordered French forces to leave.

The expulsions reflected deep anti-French sentiment fueled by perceptions that France's military presence had failed to improve security while perpetuating neo-colonial economic relationships. Junta leaders leveraged this sentiment to consolidate domestic support. The United States, which maintained drone bases and special operations forces in Niger, was similarly expelled in 2024, closing a critical intelligence, surveillance, and reconnaissance hub that had supported counterterrorism operations across the region.

Western nations are now pursuing an "over-the-horizon" approach, maintaining counterterrorism partnerships with coastal West African states like Ivory Coast, Ghana, and Benin to prevent jihadist expansion southward. The EU has redirected security assistance from Sahel junta states to their neighbors. AFRICOM continues to monitor the region but with significantly reduced access and capability compared to the pre-coup period. The strategic concern is that the Sahel becomes a permanent ungoverned space that exports instability, migration, and terrorism to North Africa, Europe, and the broader continent.

Humanitarian Impact

The security crisis has produced one of the world's most severe humanitarian emergencies. As of 2025, more than 3 million people are internally displaced across the central Sahel - Mali, Burkina Faso, and Niger - with Burkina Faso alone hosting over 2 million IDPs. Cross-border refugee flows into coastal states have strained host communities with limited resources. Food insecurity affects an estimated 45 million people across the broader Sahel region, driven by conflict, climate change, and disrupted agricultural production.

Humanitarian access has deteriorated sharply under junta governments. Aid organizations face bureaucratic restrictions, movement limitations, and security threats from both jihadist groups and government forces. In Burkina Faso, entire regions have been effectively cut off from aid delivery as jihadist sieges blockade towns and military operations restrict civilian movement. Schools and health facilities across the region have been forced to close - an estimated 8,000 schools are shuttered in the central Sahel, affecting over 1.5 million children.

The crisis also drives irregular migration toward North Africa and Europe. The Sahel serves as a primary transit route for migrants and refugees heading north through Libya, Algeria, and Tunisia. The collapse of governance in key transit zones has empowered smuggling networks while making the journey more dangerous. European migration policies increasingly focus on Sahel stability as a root-cause issue, though effective engagement is complicated by the political rupture with junta governments.
