The record 23,872 fatalities linked to African militant Islamist groups over the past year sustain a pace of more than 20,000 such deaths observed since 2023.

The rising level of annual fatalities (for the 12 months ending in mid-2026) was propelled by a 60-percent spike in deaths in the Lake Chad Basin and Mozambique.

The Sahel continues to account for more reported fatalities than any other region in Africa with 42 percent of the total. This is followed by 28 percent each from Somalia and the Lake Chad Basin. These regional patterns mirror the trajectory of militant Islamist violence in Africa in recent years. Of roughly 166,000 people killed by extremist violence in Africa over the past decade, 92 percent were in the Sahel, Somalia, and the Lake Chad Basin.

Although 15 African countries experienced some degree of militant Islamist violence over the past year, 94 percent of these fatalities have occurred in 5 countries: Somalia, Nigeria, Burkina Faso, Mali, and Niger.

The pace of violence has accelerated: the 23,872 fatalities over the past year reflect a 77-percent increase from 2021.

The pace of this violence has accelerated. The 23,872 fatalities over the past year reflect a 77-percent increase from the 13,507 deaths in 2021 and a nearly 150-percent spike from the 10,002 deaths reported in 2017.

Four out of the five theaters have seen an increase in fatalities over this decade. Only North Africa oversaw the opposite trajectory.

The past year also saw a 42-percent increase in fatalities (from 4,221 to 5,980 deaths) linked to remote violence. While an estimated 80 percent of these are from airstrikes, fatalities linked to drones are growing, reflecting the shifting tactics employed by both African militaries and militant Islamist groups.

The 9,928 reported fatalities linked to militant Islamist groups in the Sahel are more than any other region in Africa.

There have been 49,000 deaths linked to violent extremism in the Sahel since 2022.

The past year has seen a 78-percent decline in fatalities in both Benin and Togo.

With the growing use of air strikes and drone deployments, remote violence now accounts for roughly 40 percent of fatalities in Somalia.

The sharp increase in Lake Chad Basin fatalities was largely an outcome of a 92-percent increase in battle-related deaths, underscoring a stepped-up effort to confront the militant groups.
