Prolonged conflict, proxy wars, and inter-communal strife characterize many regions in Africa. This violence has caused untold atrocities, deaths, sexual violence, and displacement, as well as accelerating poverty and shattering lives and communities across the continent. Uncontrolled arms in Africa fuel this violence and are increasingly putting lives at immense risk. This report provides evidence about the human costs of uncontrolled arms: injuries and fatalities, internally displaced people and refugees, gender-based violence, and erosion of social cohesion and communal trust. Covering Mali, Central African Republic, South Sudan, Sudan, Democratic Republic of Congo, Somalia and Libya, it provides arms control recommendations to African states, the African Union and Regional Economic Communities, donor communities, and the private sector.
