New York - The United Nations Security Council unanimously adopted a resolution aimed at preventing terrorists from acquiring weapons, particularly small arms and light weapons, that pose threats to international peace and security. UN Member States were encouraged to prevent and disrupt the flow of military equipment, unmanned aircraft systems (UASs) and their components, and improvised explosive device (IED) between and among groups like the Islamic State of Iraq and the Levant (ISIL/Da'esh), Al-Qaida, their affiliates, and associated groups, illegal armed groups, and criminals. UN Member States were also urged to strengthen their judicial, law enforcement and border-control capacities, and develop their capabilities to investigate arms-trafficking networks in order to address the link between transnational organized crime and terrorism.
