This paper presents an overview of large-scale violence by Islamist extremists in
key African countries. The paper builds on previous publications of the Institute for
Security Studies on the nexus between development and conflict trends, and it seeks
to provide an overview of the evolution of the associated terrorism through
quantitative and contextual analysis using various large datasets. The focus is on the
development and links among countries experiencing the worst of this phenomenon,
especially Algeria, Egypt, Tunisia, Libya, Mali, Nigeria and Somalia, as well as the
impact of events in the Middle East on these African countries.
