The trafficking of firearms and their use in criminal violence in Europe has received significant attention from researchers and policymakers. Less is known, however, about the illicit proliferation of firearm ammunition and other explosive munitions. Currently, detailed data on illicit munitions in Europe can only be accessed through specialized law enforcement agencies. National seizure statistics often lack the necessary detail for policy-relevant analysis, as do the media reports, which often include incomplete or inaccurate information on the types and calibres of ammunition. 

KEY FINDINGS • Calibres typically associated with handguns and widely available commercial brands of ammunition usually represent the bulk of the illicit firearm ammunition seen in the countries studied. • Illicit firearms ammunition is not necessarily trafficked from abroad, as shown by the misuse of domestically produced cartridges in the five surveyed countries. Moreover, cartridges produced legally within the European Union (EU) have been recovered the same year at crime scenes. • A large percentage of illicit hand grenades and other factory-produced explosive munitions seized in the European countries under review were manufactured in the former Yugoslavia. The seizures are consistent with media reports and government statements indicating that the Balkans are a major source of illicit grenades acquired and used by criminals in the EU. • The number of illicit grenades documented in the Netherlands and Sweden has decreased significantly in recent years, possibly owing to Covid-19-related travel and shipping disruptions, an increased reliance on other types of explosives by criminals, and national and regional counter-trafficking efforts.

On a regular basis, news stories appear in the media about public shootings where shooters use their guns to open fire and kill people in shopping malls or on school campuses. Mostly these stories deal with incidents in the United States. Over the last years, however, a number of European countries have experienced similar public shooting incidents. Notable cases were the shootings at Tuusula and Kauhajoki in Finland (2007 and 2008), the killings in Cumbria in the UK (2010), the Utøya attacks by Anders Breivik in Norway (2011), and the shootings at Alphen aan den Rijn in the Netherlands and Liège in Belgium in 2011. Public shootings draw a high level of media attention. Less striking in the public eye, but not less significant – not least in quantitative terms –, are the numbers of people in Europe killed by firearms in the context of gun-related crime or in domestic shootings.

The primary focus of this study is on illegal weapons trade in Romania and the Caucasus region of the former USSR. Illegal weapons traffic in these regions is linked with both organized crime and terrorist activities. The main source of weapons for conflicts in the Caucasus region is corruption in Russian military circles. One well-known Arab terrorist organization, the so-called Muslim Brothers, has active connections in Romania. There is a incipient growing of trade with components, products and substances used in the manufacturing of mass destruction weapons (chemical, biological and nuclear). Free trade conventions between the CIS states facilitate illegal weapons transactions in the former USSR. In Eastern Europe there has been a steady increase of trade in components, products and substances used in the manufacturing chemical, biological and nuclear weapons. Many of the most recent Russian weapons, such as the B-94, have gone directly from the factory to the Caucasus arms bazaars. Chechen troops had the B-94 before it was issued to Russian soldiers.

This theoretical paper is published by the EUCPN Secretariat in connection with the theme of the Dutch Presidency, which is trafficking in illicit firearms. With the terrorist attacks that shook Europe the past months in hindsight, the subject is more relevant than ever. Trafficking in illicit firearms is a dangerous and deadly business, which should not be taken lightly. Because of the cross-border aspect of trafficking in illicit firearms, it is important to have a global overview. Where do the weapons come from, how do they enter the illicit market and what are the modus operandi of the traffickers? This paper should function as a base for a more prevention-orientated manual in which we will look at the difficulties and attempts to prevent trafficking in illicit firearms. Furthermore we will focus at the main international weapons and what the international agencies already do against the phenomenon. Through these actions, we hope to raise awareness concerning trafficking in illicit firearms, to exchange good practices and hopefully to propose general guidelines for a trafficking in illicit firearms policy.

Criminals purchase weapons unable to fire live ammunition legally and at low costs across Europe, converting them into lethal firearms with little to no training or expertise. The Small Arms Survey report From Legal to Lethal: Converted Firearms in Europe provides a detailed examination on the topic. Users of converted firearms include petty criminals, organized crime groups, and terrorist actors. Certain conversion techniques require some level of technical skills, but converters also make use of online, open-source tutorials to convert weapons relatively easily. While Europe has faced a range of converted weapons over the past decades, two main types of readily convertible firearms have entered into the illicit arms market in recent years: Slovak-origin acoustic expansion weapons (AEWs)—as used by Amedy Coulibaly in the Montrouge and Hypercacher Paris attacks in 2015; and Turkish-manufactured alarm pistols—currently the most prevalent converted firearm in Europe.

This edited volume offers an in-depth and detailed insight into Project SAFTE’s research findings. In-depth country studies were conducted in eight EU member states by research teams from the Flemish Peace Institute, SIPRI, SSSA, Arquebus Solutions, Small Arms Survey and Bureau Bruinsma. The in-depth qualitative research methodology involved desk research and semi-structured interviews with key international actors and stakeholders such as Europol, EMPACT Firearms, Interpol, SEESAC and the Office of the EU Counter-Terrorism Coordinator. The volume sheds light on how illegal firearms markets are structured in the EU and shows how terrorists access these.
