To contribute to the existing pool of evidence on the dynamic interplay between illicit trade and armed conflicts, this report looks at illicit trade flows in four separate conflict-affected countries in the MENA region: Iraq, Libya, Syria and Yemen. For the case of Yemen, the report also presents a deep-dive analysis of illicit trade flows and the relevant governance environment. The findings highlight that illicit trade networks in these countries are dynamic, complex, and heavily integrated into regional and global networks.
