Violent extremism and terrorism
Terrorism deaths fell 28% in 2025 to 5,582 — but the Sahel now accounts for over half of all deaths, and deaths in the West surged.
How this affects people
Violent extremism of every ideology targets civilians to spread fear and destabilise societies.
Most deaths are concentrated in a handful of countries with weak state presence, especially in the Sahel.
