Sahel Security: Algeria Votes to Send Troops to Niger

Algeria spent more than $25bn on its armed forces in 2025, making it the largest military spender in Africa. The country is now deploying that power to a neighboring state. Algeria’s Parliament voted on Sunday to authorize the deployment of troops to Niger. This marks a major departure from the North African nation’s historical doctrine of nonintervention.

The People’s National Assembly, the lower house of the legislature, ratified the proposal on Sunday. The Council of the Nation, the upper house, had unanimously approved the measure earlier that day. Officials have not yet released specific figures regarding the number of soldiers or the exact timeline for their arrival in Niamey.

The deployment aims to protect economic assets. According to The Associated Press, Algerian Senator Belkacem Boulghiti stated that troops would be sent to protect Algeria’s economic and strategic interests, particularly its oil facilities in Niger. These installations belong to Sonatrach, the state-owned energy company. Boulghiti told reporters after the vote that the mission is to secure economic infrastructure rather than to wage war.

Recent diplomatic shifts paved the way for this military step. Relations between Algiers and Niamey improved after Niger’s President Abdourahamane Tchiani visited Algeria in February. Months later, Niger’s Defense Minister Salifou Mody traveled to Algiers to discuss security cooperation. This thaw followed a crisis in April when the Algerian army shot down a Malian drone, prompting Niger, Mali, and Burkina Faso to recall their ambassadors from Algiers.

The move also fits into a broader realignment of the Sahel region. Algeria shares long borders with Mali, Niger, and Libya, making instability in the south a direct security concern. Since 2012, Mali, Burkina Faso, and Niger have experienced six military coups. These uprisings often followed periods of deteriorating security and political grievances. The region has seen a departure of Western forces and a rising Russian presence since France withdrew troops from the area between 2022 and 2023.

Algeria’s constitution allows for overseas deployments under specific conditions. Article 91 of the 2020 constitutional revision permits the president to authorize such moves if at least two-thirds of the members of each parliamentary chamber support them. This legal framework provides the basis for the current action, which follows a pattern of increasing willingness for Algiers to assert its security interests beyond its borders.
