The nature of domestic politics, geo-strategic positioning and socio-political and economic vulnerability of the Democratic Republic of Congo (DRC) to cross-border threats and evolving global security dynamics have sustained the growing concerns on the scourge of terrorism in the country. The DRC has for over five decades grappled with armed conflicts and wars that sustain the availability of combatants and illicit arms and light weapons, weaken political control over the vast territory while also rendering enormous population gullible for recruitment and radicalization to violence. The challenge of terrorism in DRC is further deepened by the availability of poorly governed spaces within its territory that serve as a sanctuary for terrorist groups planning and launching cross-border attacks on neighbouring countries. Yet, despite measures adopted by the Government of DRC to mitigate the threat, the vast porous borders, the presence of several non-state armed groups especially the Allied Democratic Front (ADF) which has mutated into the Islamic State in Central Africa Peninsula (ISCAP) continue to expose the country and neighbours to heightened risks of terrorist attacks. Drawing from the above, the paper concludes that combating terrorism in the DRC requires sustained national, regional and international engagements.
