This report is part of a series of four EASO COI reports on Somalia that are going to be produced in 2021. The report provides information relevant for international protection status determination for Somali applicants, and in particular for use in EASO’s country guidance development on Somalia. The report is meant to provide the background information and mapping of relevant actors/dynamics in Somalia, upon which subsequent reports (notably the Somalia Security Situation, the report on Targeted Profiles and the report on the Key Socio-Economic Indicators) will build. The report, EASO COI Report: Somalia – Actors is divided into seven macro-chapters. Chapter 1 provides a general overview of the various conflict dynamics in the country (Country Background). Chapters 2 to 6 describe the main country-wide actors in Somalia and in the Somali conflict, namely: the Federal Government of Somalia, al-Shabaab, the clans and militias, AMISOM and AFRICOM, and ISIS-Somalia. For each one of these, the report details strengths, characteristics, justice provision and relative human rights conduct/abuses by various actors. Chapter 7 provides an overview of the the Federal Member State (Jubbaland, South West State, Hirshabelle, Benadir/Mogadishu, Galmudug, Puntland), as well as Somaliland. Each regional sub-chapter includes a brief description of relevant dynamics, territorial control, governance, local armed forces, access to justice, as well as security forces’ human rights conduct.
