Africa’s Militant Islamist Threat: Near-Record Fatalities and an Expanding Operational Footprint in 2025

The Africa Center for Strategic Studies’ report, “The Widening Scope of Africa’s Militant Islamist Threat” (April 2026), shows that militant Islamist groups across Africa killed nearly 24,000 people in 2025—a 24 percent increase from the prior year—while generating 8,375 violent events, the highest number ever recorded on the continent. These numbers reflect a broad, sustained escalation across multiple operational environments simultaneously, driven by increasingly capable and organizationally sophisticated adversaries. Please see the report for a full theater-by-theater breakdown with detailed charts for each region!

The distribution map below shows that active militant Islamist groups now operate across an arc stretching from Algeria and Libya in the north, through the Sahel’s Mali-Burkina Faso-Niger corridor, into the Lake Chad Basin, east into Somalia and Kenya, and south into Mozambique. Many of these groups maintain overlapping affiliations, share fighters and resources, and coordinate across borders in ways that outpace the regional security architectures designed to counter them.

Three theaters—the Sahel, Somalia, and the Lake Chad Basin—collectively account for 98 percent of all militant Islamist-linked fatalities on the continent, as the fatalities chart below illustrates. The Sahel alone accounts for 41 percent of total deaths, a position it has held for five consecutive years, while Somalia registered the most dramatic single-year surge with fatalities nearly doubling, and the Lake Chad Basin reversed a five-year downward trend with a 28 percent increase.

Fatalities Linked to Militant Islamist Groups in Africa by Theater

These fluctuations indicate that threat groups are learning, adapting, and pressing operational advantages in permissive environments. Equally concerning, heavy-handed responses by Sahelian security forces and Russian paramilitary elements have actively fueled jihadist recruitment, meaning the current counterinsurgency approach is generating more fighters than it removes.
