Foreign terrorist fighters (FTFs) are increasingly integrating into Islamist militant groups across sub-Saharan Africa, with some Islamic State (IS) affiliates now comprising over 30% foreign personnel.
The Shift of Foreign Fighters to African Militant Groups
While the collapse of the Islamic State’s territorial control in Baghouz in 2019 didn’t trigger an immediate mass migration, it created a long-term pipeline. According to analysis by Kim Cragin, foreign terrorist fighters now make up a significant portion of specific regional forces. As of late 2024 and early 2025 estimates, FTFs constitute approximately 53% of IS-Somalia and 33% each of IS-West Africa and IS-Sahel.
This migration isn’t a sudden surge but a steady climb. Recruits aren’t moving into vacuums; they follow momentum. For years, the Islamic State remained focused on Iraq and Syria. However, the group’s official newsletter, al-Naba, began consistently highlighting African operations by 2023, signaling to global recruits that the “center of gravity” for the movement had moved.
Comparison of Foreign Fighter Presence by Affiliate
Not all militant groups in Africa attract foreigners at the same rate. The level of foreign integration varies significantly between the Islamic State’s network and al-Qaeda’s affiliates.
| Group Affiliate | Estimated Foreign Fighter Composition | Trend |
|---|---|---|
| IS-Somalia | ~53% | High Integration |
| IS-West Africa | ~33% | Moderate Integration |
| IS-Sahel | ~33% | Moderate Integration |
| al-Shabaab (al-Qaeda) | Lower Proportions | Steady/Localized |
Why the Sahel and Somalia are Primary Targets
The “pull” factor is often tactical success. When a group captures territory or executes high-profile attacks, it attracts “travelers,” including individuals from Western nations like the United States.

Frequently Asked Questions
Do foreign fighters still travel to Iraq and Syria?
While some activity remains, the operational momentum has significantly decreased compared to the 2014–2019 period.
Which group is more attractive to foreign fighters?
Current data suggests the Islamic State (IS) affiliates in Africa have a higher percentage of foreign personnel compared to al-Qaeda affiliates like al-Shabaab, largely due to IS’s centralized global branding and recruitment efforts.
