This study explores accountability for war crimes in Niger under international criminal law (ICL), a critical area within African and global legal landscapes. A mixed methods approach was employed, integrating qualitative insights from structured interviews with quantitative data gathered via a survey. Data collection involved face-to-face meetings and online questionnaires distributed across multiple regions of Niger. Findings suggest that while the legal framework for war crimes accountability is in place, its implementation faces significant challenges related to access to justice, particularly affecting marginalized communities such as nomadic herders. The mixed methods study reveals disparities in how ICL mechanisms are perceived and applied across different socio-economic groups within Niger. This highlights the need for tailored legal interventions that address practical barriers to justice. Specific recommendations include enhancing public awareness campaigns, improving access to legal aid services, and strengthening community-based support systems to ensure comprehensive accountability for war crimes victims in Niger.
