The Rise of Isis-Somalia’s Global Expansion Agenda: Implications for Horn of Africa Security

Executive Summary

The growing foothold of the Islamic State of Iraq and Syria (ISIS) in Somalia threatens to destabilize the Horn of Africa’s (HoA) regional security architecture. ISIS-Somalia, which seeks to establish a global caliphate in collaboration with other ISIS factions worldwide, continues to expand by recruiting fighters from within the region and beyond. The group’s strategic objective is to position Somalia as a key operational base for its broader jihadist network, further destabilizing the region and exacerbating security challenges. This escalation complicates ongoing counter-terrorism efforts such as the African Union Stabilization Mission in Somalia (AUSSOM), particularly given the persistent threat posed by the Al-Shabaab terrorist group, which remains active in Somalia. The brief opines that this development has significant implications for regional geopolitics, maritime security in the Western Indian Ocean and the Red Sea, and heightens the risk of instability across the HoA region. Key recommendations include enhancing intelligence-sharing mechanisms; prioritizing the disruption of ISIS-Somalia’s revenue streams; bolstering maritime security in the Western Indian Ocean through improved naval patrols; reinforcing Somalia’s security forces through increased participation in training and capacity-building programs; and intensifying efforts to dismantle the group’s cells and conduct targeted strikes on its hideouts.
