The Global Terrorism Index 2026 reports a decline in terrorism-related violence in several Sahel countries in 2025, although the region remains the most affected in the world.
Countries like Burkina Faso and Mali have recorded a significant decrease in the number of deaths, while Niger has also experienced fewer attacks, reflecting a fragile but notable improvement in security.
However, the report underlines that the Sahel remains responsible for more than half of the world's terrorism-related deaths, due to the persistent activity of groups such as JNIM and the Islamic State.
It highlights persistent challenges, such as weak state control, cross-border threats and socio-economic factors fueling recruitment, despite increased military cooperation between Sahel states under initiatives led by Assimi Goïta and regional alliances.
In the central Sahel, the report's data shows significant declines. Burkina Faso recorded the largest decrease in the world in the number of deaths (-45%), while Mali saw a decrease for the third consecutive year (-42%). Niger, although still ranked among the most affected countries, also recorded a decrease in attacks and casualties.
