The United Nations (UN) headquarters convened this week to address the persistent global proliferation of illicit firearms, weapons that continue to fuel violence long after conflicts have ended. Central to the discussions are emerging technologies that experts warn could facilitate the production and obscure the tracking of these illegal arms.
Izumi Nakamitsu, the UN’s top disarmament official, stated in an interview with UN News, “Wars end – but unfortunately, the weapons used in that conflict do not come under full control. They continue to circulate. Sometimes they are hidden. They are moved across borders.”
‘Ghost Guns’ and 3D-Printed Firearms Pose New Challenges
A rapidly growing concern involves firearms known as ‘ghost guns.’ These weapons lack serial numbers and are assembled from parts or kits, making them nearly impossible for authorities to trace. Advancements in 3D printing technology have introduced further complications, enabling the production of components and, in some cases, fully functional firearms outside traditional manufacturing and regulatory systems. The increasing accessibility and affordability of this technology have heightened concerns among governments about the potential for easier production and more difficult regulation of illicit firearms. “These weapons or parts of weapons, if they are dismantled and trafficked, are more difficult to trace,” Nakamitsu added.
Understanding Small Arms and Light Weapons
Small arms, such as handguns, revolvers, and assault rifles, can be carried and operated by a single individual. Light weapons encompass systems that can be operated by a small crew, including grenade launchers, machine guns, and portable anti-aircraft or anti-tank weapons. Due to their relative low cost, durability, and ease of use, these weapons can remain in circulation for decades. Ammunition is also a critical part of the challenge. Even if weapons are already circulating illicitly, continued access to ammunition can prolong their use in conflict, crime, and terrorism.
Weapons Linger After Conflicts Cease
Libya is frequently cited as an example. Weapons looted or diverted during the 2011 conflict following the end of the Muammar Gaddafi regime have since surfaced across the wider Sahel region, including in Niger, Burkina Faso, and Nigeria. Some have subsequently fallen into the hands of extremist groups, demonstrating how weapons from one conflict can destabilize neighboring countries years later. “The end of a conflict does not mean the end of the circulation of these weapons… they remain and continue to harm people,” Nakamitsu observed.
From Crime to Conflict
The impact is widespread, varying by region. In Latin America and the Caribbean, illicit firearms are closely linked to organized crime and some of the world’s highest homicide rates. The UN estimates that firearms account for 70 to 80 percent of violent deaths in some parts of the region. In parts of Sub-Saharan Africa, the proliferation of small arms can undermine peacebuilding efforts long after conflicts have subsided. Weapons held by armed groups, militias, or communities for self-protection can contribute to renewed violence and instability.
Beyond Security Concerns
The consequences extend far beyond conflicts. Illicit arms are linked to human rights abuses, terrorism, and sexual violence. “This is not just a security issue. It is also about peacebuilding, about human rights, and also about development,” Nakamitsu said. Recognizing the dangers of small arms and light weapons, the UN adopted an Programme of Action in 2001, where member states committed to strengthening national legislation, improving stockpile security, combating illicit trafficking, and expanding international cooperation. A significant milestone was reached in 2005 with the adoption of the International Tracing Instrument, establishing global marking, record-keeping, and tracing standards for illicit arms. This framework helps investigators determine the origin of illicit weapons and how they enter illicit markets, while reducing the risk of diversion from legal stockpiles. The UN supports implementation through technical assistance, policy guidance, and capacity-building programs aimed at helping governments secure arms stockpiles, improve tracing systems, and strengthen border controls.
Why It Matters
Former Secretary-General Kofi Annan noted that small arms could be the world’s true “weapons of mass destruction” due to the immense number of deaths and injuries they cause. The challenge is ultimately about more than just lethal weapons; it is about reducing violence, protecting communities, and preventing the resurgence of conflicts. Nakamitsu emphasized that reducing the circulation of illicit firearms would benefit all societies. “This is a real problem for many people. We want the proper control and regulation of small arms in all societies. That will certainly make the lives of everyone safer and more secure,” she concluded.
