This policy paper aims to explore the new flows and trade of illicit arms across the MENA region that have created and continue to feed ongoing conflicts, most notably in Libya, Syria, Iraq, and Yemen. This situation threatens the human and national security of the region�s nations. Combatting war economy activities in war-ridden countries will be a critical issue in the post-conflict context, and this pertains to countering small arms and light weaponry transfers that may reignite conflicts on both communal and ethnic levels. Examining illicit arms transfers in Libya and Yemen, the paper draws policy options that address the economic, social, and political aspects of this threat. Consequently, it will investigate the existing international legal framework and mechanisms employed by regional and international organizations such as the African Union (AU) and the UN, as well as how to fill the gap between them and the national authorities in charge of stemming out this threat.
