• This report explores the role of antisemitism in mobilizing extremist and terrorist actors to violence, focusing on trends and patterns across France, Germany, Hungary, Poland and the United States. It discusses antisemitic narratives, key antisemitic actors, transnational connections, dissemination strategies, and provides policy recommendations. • Antisemitic narratives serve as tools to justify violence across ideological lines, framing Jewish communities and individuals as threats or scapegoats. Rightwing extremists propagate conspiracy theories like the “Great Replacement,” portraying Jews as orchestrating adverse societal change. Islamist extremists often conflate Jewish identity with global oppression, particularly in the Israeli-Palestinian conflict. Left-wing extremists link Jews to capitalism or imperialism, using antizionism to mask antisemitism. These narratives are adapted to local and geopolitical contexts, reinforcing the targeting of Jewish communities and individuals. • The report documents a sharp increase in antisemitic incidents following the October 7, 2023, Hamas attacks and ensuing war. Violent antisemitic rhetoric has spiked in demonstrations and online discourses. Islamist extremist networks, left-wing extremist actors and pro-Palestinian extremist groups have particularly amplified violent antisemitic sentiments under the guise of antizionist rhetoric, sometimes overlapping with traditional right-wing antisemitic themes. • Transnational networks facilitate the spread of antisemitic narratives. Right-wing extremist groups connect online and through events and annual marches, while Islamist extremist groups leverage shared ideological or religious frameworks to justify violence. Left-wing extremist and pro-Palestinian extremist groups maintain operations across Europe and in the U.S., amplifying violent antisemitic narratives. Shared slogans, symbols, and coordinated protests underline their interconnectedness. • In some countries, an increase in violent attacks against Jewish or Israeli targets has been documented. • The report emphasizes that the concept of combatting organized antisemitism should be added to strategies that aim at targeting violence-oriented antisemitic actors. Such professional organized antisemitic actors often operate in (transnational) networks, utilizing online platforms and offline activities to propagate hate and justify or conduct violence. • The report also calls attention to the role of states like the Islamic Republic of Iran and the Russian Federation in fostering violent antisemitism through proxies and propaganda. • Policy recommendations include focusing on identifying and disrupting key antisemitic actors, enhancing data collection and analysis, and fostering international collaboration. The report also stresses the need for tailored preventative and educational initiatives and stricter online content regulation and enforcement to combat the spread of antisemitism and its violent manifestations.

  This systematic review unveils significant convergence between cybercriminals and terrorists over the past decade, characterized by substantial overlap in tactics, capabilities, and infrastructure exploitation. Key findings illuminate the adoption of cybercriminal methods by terrorist organizations, the engagement of cybercriminal groups in terrorist activities, the proliferation of enabling technologies such as cryptocurrencies and the dark web, and the role of social media in facilitating knowledge exchange between diverse threat actors. While direct terrorist involvement in proftdriven cybercrime appears limited, the escalating convergence underscores urgent imperatives for enhanced cooperation, legal refinement, the establishment of flexible counter-threat authorities, and collaboration with the private sector. Continuous monitoring of this rapidly evolving landscape is crucial to inform effective policies and interventions in an increasingly interconnected digital world.

The ideological influence of Jemaah Islamiyah continues to be a threat to security even after its disbandment in June 2024. Some of its former members may align with other extremist groups, while others may seek to operate as lone-wolf terrorists. The possibility of JI’s former members transitioning into lone wolf actors stems from the enduring power of its ideology and indoctrination process.

In 2024, Bangladesh faces a growing threat of radicalism fuelled by political instability, security vacuums, and weakened counterterrorism infrastructure. Unless the interim government adopts a zero-tolerance policy and strengthens law enforcement and intelligence efforts, extremist groups may gain further ground, leading to long-term instability. COMMENTARY Bangladesh is facing an increasing threat of radicalism and terrorism. The political violence and instability of 2024 have worsened the situation, with extremist elements exploiting the security vacuum created by the regime change. Weakened law enforcement and intelligence agencies, along with the rise of armed groups and radical ideologies, pose a serious threat to the country’s stability. Bangladesh risks long-term insecurity with broader regional implications without swift and decisive action.

The conflicts in Israel, Gaza, Lebanon, Yemen and Syria will have a generational impact. The 7 October 2023 attack against Israel in Gaza and its consequences have set back the prospects of a two-state solution to the Palestinian issue and may attract a new wave of foreign fighters to embark on terrorist activities like what was seen following the military debacles in Afghanistan, Iraq and Syria. What can be done to stem another rise of the terrorist fighters?

Objectives: We examine the association between perceived discrimination, mental health, social support, and support for violent radicalization (VR) in young adults from three locations across two countries: Montréal and Toronto, Canada, and Boston, United States. A secondary goal is to test the moderating role of location. Methods: A total of 791 young adults between the ages of 18 and 30, drawn from the Somali Youth longitudinal study and a Canada-based study of college students, participated in the study. We used multivariate linear regression to assess the association between scores on the Radical Intentions Scale (RIS) with demographic characteristics, anxiety, depression, social support, and discrimination. Results: In the full sample, discrimination, age, and gender were associated with RIS scores. When we examined moderation effects by location, RIS scores were associated with depression only in Montréal, and with social support (negatively) and discrimination in Toronto. None of the variables were significant in Boston. Conclusion: These findings suggest that an understanding of risk and protective factors for support of VR may be context-dependent. Further research should take into consideration local/regional differences

Abstract Background: Two of the most central questions in radicalization research are, (1)why do some individuals radicalize when most of those from the same groups or exposed to similar conditions do not? and (2) why do radicalized individuals turn to radical violence while the majority remain inert? It has been suggested that the answer to both questions lie in the cumulative and interactive effects of a range of risk factors. While risk assessment and counter‐radicalization take a risk‐protectivefactor approach, there is widespread debate as to what these factors are and which are most important.Objectives: This review has two primary objectives.1) To identify what the putative risk and protective factors for different radica-lization outcomes are, without any predeterminations.2) To synthesize the evidence and identify the relative magnitude of the effects of different factors.The review's secondary objectives are to:1) Identify consistencies in the estimates of factors across different radicalizationoutcomes.2) Identify whether any significant heterogeneity exists within factors between(a) geographic regions, and (b) strains of radicalizing ideologies.Search Methods: Over 20 databases were searched for both published and gray literature. In order to provide a more comprehensive review, supplementary sear-ches were conducted in two German and one Dutch database. Reference harvesting was conducted from previous reviews and contact was made with leading researchers to identify and acquire missing or unpublished studies.Selection Criteria: The review included observational studies assessing the out-comes of radical attitudes, intentions, and/or radical behaviors in OECD countries and which provided sufficient data to calculate effect sizes for individual‐level risk and protective factors.Data Collection and Analysis: One‐hundred and twenty‐seven studies, containing 206 samples met the inclusion criteria and provided 1302 effect sizes pertaining to over 100 different factors. Random effects meta‐analyses were carried out for each factor, and meta‐regression and moderator analysis were used to explore differ-ences across studies.Results: Studies were primarily cross‐sectional, with samples representing 20 OECD countries. Most studies examined no specific radicalizing ideology, while others focussed on specific ideologies (e.g., Islamist, right‐wing, and left‐wing ideologies). The studies generally demonstrated low risk of bias and utilized validated or widely acceptable measures for both indicators and outcomes.With some exceptions, sociodemographic factors tend to have the smallest estimates, with larger estimates for experiential and attitudinal factors, followed by traditional criminogenic and psychological factors.Authors' Conclusions: While sociodemographic factors are the most commonly examined factors (selective availability), they also tend to have the smallest es-timates. So too, attitudinal and even experiential factors, do not have effect sizes of the magnitude that could lead to significant reductions in risk through tar-geting by interventions. Conversely, traditional criminogenic factors, as well as psychological factors tend to display the largest estimates. These findings suggest the need to broaden the scope of factors considered in both risk assessment and intervention, and this review provides much needed evidence for guiding the selection of factors

The horrific attacks by Hamas on October 7, 2023, fundamentally shifted the security posture of the Middle East, while also having severe humanitarian consequences and ripple effects in countries throughout the globe, including many in the West. This TSC Special Report, generously sponsored by the Airey Neave Trust, aims to explore how October 7 impacted several Western countries, including the United States, the United Kingdom, France, Germany, and Italy. While the conflict remains ongoing – and indeed will reverberate long after the fighting actually ends — this report attempts to take the pulse of five Western countries just shy of the one-year anniversary marking the attack.

Perhaps unsurprisingly, and in line with trends that have been unfolding in recent years, there has been a spike in both Islamophobic and antisemitic incidents across all five countries — it is not an either/or phenomena. Still, the data underpinning these incidents remains challenging, limited, and frequently incomplete, often collected by civil society groups or non-profit organizations with different definitions of the terms. Government data varies on how it is collected, if it is recorded at all, across local, state, and federal levels. This makes it exceedingly difficult to compare the data rigorously and make generalizable conclusions with confidence. The data that is available, however, does suggest that extremist groups are leveraging the conflict to promulgate and amplify preexisting antisemitic and Islamophobic narratives. In other words, the terrorist attacks of October 7 and the Israeli response provide an opportunity to promote their hateful narratives and repackage them for the moment, often inciting their followers to wreak havoc and pushing their supporters to engage in violence.

How does the internet affect the radicalisation of extreme-right lone actor terrorists? In the absence of an established theoretical model, this article identifies six mechanisms seen as particularly relevant for explaining online radicalisation. Having first reviewed a larger set of relevant lone actor terrorists, the study traces the mechanisms in three selected cases where the internet was reportedly used extensively during radicalisation. The findingsshow that the internet primarily facilitated radicalisation through information provision, as well as amplifying group polarisation and legitimising extreme ideology and violence through echoing.In all three cases, radicalisation was also affected considerably byoffline push-factors that through their presence made extreme online messages more impactful. The results challenge the view that offline interaction is necessary for radicalisation to occur but also the view that online influence itself is sufficient

The following excerpt from the document contains multiple links embedded in the original text: "Islamic State (IS) recently released a powerful recruitment message for 'distracted Muslim youth' to travel and join IS territories across the world. It highlights a disturbing trend in how terrorist organisations are using technology to recruit and mobilise members through a single message. It also shows that contemporary terror groups and extremist organisations are adapting fast to emerging technologies. This Insight aims to highlight an alarming reality: the exploitation of Artificial Intelligence (AI) technology by terrorist and violent extremist groups to strengthen recruitment efforts. These groups proficiently manipulate online platforms, leveraging sophisticated AI tools to disseminate tailored propaganda content to exploit psychological vulnerabilities and amplify divisive narratives, thereby fostering radicalisation and recruitment. From using encrypted messaging apps like Telegram and WhatsApp to seeking refuge in the anonymity of the Dark Web, these groups employ various tactics to evade AI detection and exploit vulnerabilities. By leveraging AI tools, these groups engage in personalised messaging, rapid distribution, and exploitation of social media algorithms to amplify their reach and influence susceptible individuals."

The following excerpt from the document contains multiple links embedded in the original text: "'Content Warning: This insight contains antisemitic, racist, and hateful imagery.' [...] Extremists exploit social media platforms to spread hate against minority groups based on protected attributes such as gender, religion, and ethnicity. Platforms and researchers have been actively developing AI tools to detect and remove such hate speech. However, extremists employ various forms of implicit hate speech (IHS) to evade AI detection systems. IHS spreads hateful messages using subtle expressions and complex contextual semantic relationships instead of explicit abusive words, bringing challenges to automatic detection algorithms. Common forms of IHS include dog whistles, coded language, humorous hate speech, and implicit dehumanisation. Moreover, the forms and expressions of IHS evolve rapidly with societal controversies (e.g., regional wars). Identifying and tracking such changes in IHS is crucial for platforms trying to counter them. In this Insight, we report and analyse 'Substitution' as a new form of IHS. Recently, we observed extremists using 'Substitution' by propagating hateful rhetoric against a target group (e.g., Jews) while explicitly referencing another label group (e.g., Chinese). We show that Substitution not only effectively spreads hate but also exacerbates engagement and obscures detection."

From the document: "[1] The Biden administration set forth five main objectives in reaction to the Oct. 7 Hamas attack against Israel and ensuing war in the Gaza Strip: [a.] Support Israel's self-defense and objective of eliminating the threat posed by Hamas; [b.] Secure the safe return of hostages; [c.] Prevent a wider regional war; [d.] Protect civilians and respond to a growing humanitarian crisis in Gaza; and [e.] Create a post-war plan for reconstruction leading to a two-state solution and wider regional normalization efforts in coordination with regional and international partners. [2] Six months into the Israel-Hamas war, the Biden administration has not achieved enough progress toward these goals, although it has avoided some of the worst-case scenarios. Success is hampered in part by tensions stemming from the fact that some of the tactics and policy approaches are at odds with each other."

Risk assessment for violent extremism plays a critical role in understanding the threat posed by radicalised offenders and determining how these individuals are managed both in correctional settings and in the community. The Australian Institute of Criminology (AIC) was engaged by the Department of Home Affairs’ Countering Violent Extremism (CVE) Branch to conduct a review of the use of risk assessments for violent extremism in Australia.

The aim of this review was to:

• identify and describe violent extremism risk assessment tools currently available to support risk assessments of convicted terrorist offenders;

• assess each tool’s suitability to assist an expert to conduct an assessment of the risk to the community from an offender, when a court is considering whether to issue a control order under Division 104 or a post-sentence order under Division 105A of the Criminal Code Act 1995 (Criminal Code); and

• review current risk assessment frameworks, including the use of Structured Professional Judgement, to assess the risk of violent extremist offending and consider how violent extremism risk assessment tools might be improved.

A review of relevant peer-reviewed and grey literature was undertaken alongside semi-structured interviews with a group of experts in violent extremism risk assessment. Findings from this review are organised according to the Terms of Reference.

This report details the findings of the research study that examined the plausibility between terrorism and banditry towards shedding new light on the dynamics of the country’s security challenges especially in northwest and north central Nigeria, within the focal context of Kaduna, Katsina, Niger and Zamfara States. Nigeria faces a plethora of security challenges ranging from the Boko Haram religious/violent extremism cum insurgency in the northeast to farmer-herder conflict and banditry in the northcentral and northeast, a revived secessionist movement in the southeast, police repression, piracy, and more recently attacks the nexus between banditry and terrorism; highlight the strategies and actions required by various stakeholders at various levels to counter the spread of banditry and terrorism in these focal states. Predominantly, the report utilises both qualitative and descriptive methods, generated from primary and secondary data gotten through desk review, and a consolidation of findings with feedback from consultations with stakeholders in selected focal states. The report undertook qualitative research in the focal states, documenting the experiences of some critical stakeholders through key on security installations, among others. In spite of government efforts, the security situation in Nigeria is deteriorating. The report thus explores the question of whether banditry and terrorism are the alternate side of the same coin and the security and policy implications of conflating both. The purpose of this report is to ascertain informant interviews. These interviews were cluster-based to provide a better context to the literature and systemically present the experiences of stakeholders. The report finds that while banditry gravely endangers public safety and security in the focal states, there are contextual differences in the origin, evolution, and manifestations of banditry in the focal states. Understanding these local variations is important to deploying effective and sustainable solutions to this spectre of banditry that defines governance in the states. The report also notes that there is no discernible ideological persuasion underpinning banditry beyond theft, extortion, and wanton violence. Bandits are primarily motivated by the alluring prospects of wealth in a region blighted by poverty and poor socioeconomic outcomes. However, this does not exclude the fact that fundamentalist Islamist groups operate in the same space as bandits. There is the possibility that some bandit groups might have adopted more of a religious modus operandi on their initiative or through limited contact with extremist groups. While the report notes the dearth of studies investigating in detail the theoretical and functional nature of the relationship between banditry and terrorism in these four states, the preliminary evidence points to the existence of both environmental and operational convergence between bandits and Islamist fundamentalist groups in the focal states.

Defeating terrorism and saving art: fighting the same battle

In a world where chaos and political instability plague many countries in the Middle East and North Africa, a lesser-known crime has emerged: the trafficking of cultural goods. This phenomenon, often overshadowed by more prominent issues, poses a significant global threat. But why is the trafficking of art and antiquities so concerning?

1. Financing Terrorism: Cultural goods trafficking is not merely a trade—it’s a critical source of funding for terrorism. Security Council resolutions, UNESCO, the European Union, and financial investigation units have all documented this link. The self-proclaimed “Islamic State” even institutionalized this trade, issuing excavation permits and organizing the sale of stolen pieces to market countries.

2. Hidden Threats: Although these looted artifacts may not flood the markets immediately, history shows that they can resurface years later. Works looted by the Nazis during World War II, for instance, have reappeared after decades of concealment.

3. Beyond Terrorism: Yet, the interest in this analysis extends beyond terrorism financing. The resale of “blood antiquities” reveals another dimension: money laundering, fraud, and tax evasion. This criminal activity affects not only the antiques market but also the broader art market.

4. Investing for Tomorrow: To combat this multifaceted threat, we must invest in detecting and preventing crimes related to cultural and art objects. Whether in times of war or peace, our ability to safeguard culture and heritage depends on proactive measures.

There have been several agitations in Nigeria, but none have degenerated into the current barbaric, horrendous, heinous, and despicable dimensions of carnage, massacres, and bloodletting orchestrated by terrorists, bandits, kidnappers, and other organized violent crime syndicates. This study takes a holistic approach using secondary data sources to examine the root causes of the modern-day prevalence of kidnapping, banditry, terrorist attacks, and other organized criminal activities in Nigeria. The study finds that unemployment, excess supply of young people, neglect of certain regions in the distribution of national wealth, lack of government visibility, lack of equal economic opportunity for all, uncontrolled influx of firearms, poverty, and religious fanaticism contributes to the increasing rate of violent crime in Nigeria. The article finds that the nature of banditry, kidnapping, and terrorist attacks are similar, and the modes of attacks on civilian and government installations are also related. The government should thus become proactively visible throughout the nation via its security agencies and economic development agenda. Additionally, the government should educate local officials and traditional councils on contemporary methods for reporting and addressing violent groups in their communities.

Hidden deep in the Bavarian mountains lies the picturesque village of Oberstdorf—a place where for hundreds of years people lived simple lives while history was made elsewhere. Yet even this remote idyll could not escape the brutal iron grip of the Nazi regime.

From the author of the international bestseller Travelers in the Third Reich comes A Village in the Third Reich, shining a light on the lives of ordinary people. Drawing on personal archives, letters, interviews and memoirs, it lays bare their brutality and love; courage and weakness; action, apathy and grief; hope, pain, joy, and despair.

Within its pages we encounter people from all walks of life – foresters, priests, farmers and nuns; innkeepers, Nazi officials, veterans and party members; village councillors, mountaineers, socialists, slave labourers, schoolchildren, tourists and aristocrats. We meet the Jews who survived – and those who didn’t; the Nazi mayor who tried to shield those persecuted by the regime; and a blind boy whose life was judged "not worth living."

This is a tale of conflicting loyalties and desires, of shattered dreams—but one in which, ultimately, human resilience triumphs. These are the stories of ordinary lives at the crossroads of history.

The involvement of women in terrorism is not new, but it has gained more attention with the rise of the Islamic State in Iraq and Syria (ISIS), which attracted many women to its so-called caliphate. Initially perceived as victims or harmless, these women progressively became a growing subject of attention and concern for security services. In 2017, the Dutch intelligence service (AIVD) already indicated that the threat emanating from female jihadis should not be underestimated, while recognising knowledge gaps about the role(s) these women played in jihadi movements or the threat they posed.1 The same year, the United Nations Security Council Resolution 2396 (2017) stressed that women who were affiliated with terrorist organisations “may have served in many different roles, including as supporters, facilitators, or perpetrators of terrorist acts” and urged states to pay special attention to this as women “require special focus when developing tailored prosecution, rehabilitation and reintegration strategies.”2 Yet, in spite of more attention from counter-terrorism services, and a growing body of literature on female terrorists, there is still a considerable lack of data-driven, empirical research on female violent extremist offenders (VEOs). This book seeks to inform practitioners and policy-makers on how to manage female VEOs through the criminal justice system in a rule of law and human rights compliant manner through four case studies in Europe.

“This report presents findings from the REASSURE (Researcher, Security, Safety, and Resilience) project’s in-depth interviews with 39 online extremism and terrorism researchers. Based at universities, research institutes, and think tanks in Europe and North America, the interviewees studied mainly, albeit not exclusively, far-right and violent jihadist online activity. The report catalogues for the first time the range of harms they have experienced, the lack of formalised systems of care or training, and their reliance therefore on informal support networks to mitigate those harms.”
