This article examines the impact of social media on the wave of Palestinian lone-wolf attacks against Israelis from October 2015 through September 2016. My principal argument is that social media played an important role in shaping the identity, perceptions, and behavioral patterns of dozens of assailants, and was key in creating the dynamic that ultimately characterized both the spreading of the idea of lone-wolf attacks and its execution. Social media reflected reality on the ground while simultaneously nourishing, amplifying, and escalating the situation by providing a platform for the emergence of new sources of authority, including an online subculture with distinct codes and pseudo-ritual patterns to support assailants. Social media also contributed substantially to shaping the contagious character of the attacks, and their capacity to persist without direct organizational guidance, following a typical epidemiological dynamic of spread, containment, and preservation.

Recent terrorist attacks carried out on behalf of ISIS on American and European soil by lone wolf attackers or sleeper cells remind us of the importance of understanding the dynamics of radicalization mediated by social media communication channels. In this paper, we shed light on the social media activity of a group of twenty-five thousand users whose association with ISIS online radical propaganda has been manually verified. By using a computational tool known as dynamic activity-connectivity maps, based on network and temporal activity patterns, we investigate the dynamics of social influence within ISIS supporters. We finally quantify the effectiveness of ISIS propaganda by determining the adoption of extremist content in the general population and draw a parallel between radical propaganda and epidemics spreading, highlighting that information broadcasters and influential ISIS supporters generate highly-infectious cascades of information contagion. Our findings will help generate effective countermeasures to combat the group and other forms of online extremism.

During the fourth biennial review of the Global Counter-Terrorism Strategy held in September 2014, Member States expressed concern at the growing phenomenon of Foreign Terrorist Fighters (FTFs) in Syria. As a result, the Secretary-General announced that the United Nations Centre for Counter-Terrorism (UNCCT) would, in cooperation with those Member States that wished to participate, gather information on the motivation of FTFs through direct interviews of returnees. By analysis of the results, the Secretary-General aimed to provide Member States with a stronger knowledge base from which to understand the phenomenon of FTFs, assess the risks they posed, and develop effective responses.

Accordingly, in November 2014, the Executive Chairman of UNCCT and Under-Secretary General for Political Affairs invited all Member States to facilitate United Nations access to FTFs within their jurisdictions. Despite limited cooperation,1 UNCCT interviewed 43 individuals between August 2015 and November 2016, representing 12 nationalities. Thirty three (77 per cent) of the interviewees reached Syria but subsequently decided to leave, while the remaining ten (23 per cent) began the journey but were stopped en route, either on their own or in a transit country. Two interviewees are of Syrian origin, though they were not living in Syria when they were interviewed, while the rest fulfil the definition of foreign terrorist fighters included in Security Council resolution 2178 (2014).

The responses of the interviewees provide important insights into the motivations of individuals to leave their countries of residence or nationality to join armed groups in Syria. It is important to note that more often than not, individuals do not necessarily select the group they finally join. Rather, once they reach Syrian territory, some seem to join the group that operates closest to their point of arrival. Fighters also seem to be switching groups. The aim of this report is to expand understanding of the FTF phenomenon in Syria by examining why the interviewees chose to act in the way they did. The report records the reasons individual FTFs have given to explain their decision to leave their countries of residence or nationality to join armed groups. It also records their reasons for leaving these groups and returning to their countries of residence or nationality before achieving the goals and objectives they had set themselves. Finally, the report seeks to draw conclusions as to the threat that returning FTFs may pose in the future.

This article explores one aspect of digital politics, the politics of videos and more specifically of DAESH recruitment videos. It proposes a practice theoretical approach to the politics of DAESH recruitment videos focused on the re-production of regimes of (in)visibility. The article develops an argument demonstrating specifically how digital and commercial logics characterize the aesthetic, circulatory, and infrastructuring practices re-producing the regime of (in)visibility. It shows that digital/commercial logics are at the heart of the combinatorial marketing of multiple, contradictory images of the DAESH polity in the videos; that they are core to the participatory, entrepreneurial, individualized and affective processes of contagion determining whom the videos reach and involve; and that they shape the sorting, linking, flagging and censoring of the videos that define their accessibility on the internet. The theoretical and political cost of overlooking these digital and commercial characteristics of DAESH visibility practices are high. It perpetuates misconceptions of how the videos work and what their politics are and it reinforces the digital Orientalism/Occidentalism in which these misconceptions are anchored.

This study examines videos produced by the al-Hayat Media Center, a branch of the Islamic State’s (IS) larger media campaign aimed more specifically at Western audiences. Using a thematic analysis approach, recurring themes of 10 al-Hayat videos were identified with conclusions made regarding the specificities of the message and the target audience. It was found that al-Hayat videos cater to potential Western recruits and sympathizers by portraying life in the IS as spiritually and existentially fulfilling, while simultaneously decrying the West as secular, immoral, and criminal. By utilizing well-produced propaganda videos that tap into the dissatisfactions of Western Muslims, al-Hayat was shown to deliver a sophisticated and legitimate message that may play a role in the larger radicalization process.

Social media, and Twitter in particular, have become important sources for journalists in times of crises. User-generated content (UGC) can provide journalists with on-site information and material they otherwise would not have access to. But how they source and verify UGC has not yet been systematically analyzed. This study analyzes sourcing and verification practices on Twitter during the Brussels attacks in March 2016. Based on quantitative content analysis, we identified (1) the journalists and news organizations sourcing during the attacks, (2) classified different forms of sourcing and verification requests, and (3) analyzed the sourced UGC. Results show that sourcing on Twitter has become a global phenomenon. During the first hours of the attack, journalists rely on UGC. Their sourcing and verification practices vary widely and often lack basic verification procedures, which leads to a discussion about the ethical implications of sourcing practices.
