Europe today faces a challenge that may seem small in scale, but its political and social impact is profound. Newly released reports from Europol, examining the state and trends of terrorism in Europe for 2024, show that jihadist attacks have not only failed to decrease, but their very nature is also changing. While the main concern during the peak of the Islamic State’s caliphate (2014-2019) was coordinated operations and established networks, we are now witnessing a wave of individual, scattered attacks inspired by the online environment. This is a threat that is smaller in scale but greater in its unpredictability and political impact.
Today’s threat to Europe is a combined product of three factors: rapid online radicalization, geopolitical developments, and social divides within European societies. Numerous reports indicate that many individuals who are members of, or inspired by, jihadist groups are being made vulnerable through social media. Encrypted platforms and social media networks have become the primary means for reproducing Jihadist ideology.
A process that previously took months or years can now lead to violence in just a few weeks or even days. This change in nature has complicated the work of security agencies; they are no longer dealing with a traceable physical network, but with individuals who form in a social and identity vacuum and suddenly become operational.
Geopolitical developments have also played a role. The return of the Taliban to power in Afghanistan (August 2021) and ongoing regional crises serve a symbolic and inspirational role for some extremist movements. Even without extensive operational networks in Europe, these developments shape individuals’ mindsets and push them toward violent acts. Social divides in Europe, from economic marginalization and weak integration processes to the identity crisis faced by some second- and third-generation immigrants, have provided fertile ground for limited but dangerous recruitment by jihadist groups.
The vast majority of Muslims in Europe have no connection to extremism, but a small minority, influenced by online propaganda due to various factors (in which the policies of host countries also play a significant role), is sufficient to create a major political impact.
Despite the small scale of these attacks, their political and media consequences are vast. Every incident, whether limited in casualties or more extensive, receives wide coverage in the media and on social media networks, pushing debates on immigration, security, and civil liberties back to the top of the agenda. Far-right parties exploit this security climate to reinforce their narratives, warning that Europe is in danger and that liberal governments are unable to protect citizens. The security threat has turned into political capital.
A self-reinforcing cycle has formed: each limited attack generates a broad political reaction; the public sphere becomes more polarized; social divides widen; and the social groundwork for the next extremist act is laid. Purely security-focused policies, including increased digital surveillance and stricter measures against immigrants, if implemented without social integration programs and effective action against online radicalization, may not only fail to reduce the threat but could actually intensify it.
In many conversations I’ve had with immigrants, they complained about the integration process. They find it overly complicated and, at the same time, lacking the necessary support regarding their access to appropriate educational resources, schooling, and even housing in many European countries.
Available information shows that today, Europe is facing individuals inspired by jihadist ideologies, not a centralized army; it faces a scattered and unpredictable threat, not an organized network. This characteristic makes the threat politically more sensitive because even a small incident can accelerate the redefinition of countries’ domestic policies and solidify specific political narratives.
According to the latest information released by Europol, at least 58 terrorist acts were reported in 2024, with jihadists responsible for 24 of them, i.e., 41.4% of the total reported terrorist acts. Meanwhile, other groups carried out acts as follows: far-right 1 case (1.7%), far-left 21 cases (36.2%), nationalists and separatists 4 cases (6.9%), and the other 8 cases (13.8%). These statistics show that only terrorist acts by jihadist groups saw a serious increase compared to 2023.
Below, I will examine terrorist attacks and arrests related to Islamist jihadists, broken down by country for the years 2021, 2022, 2023, and 2024:
| No. | Country | 2021 | 2022 | 2023 | 2024 |
| 1 | France | 5 | 4 | 8 | 11 |
| 2 | Germany | 2 | 0 | 3 | 6 |
| 3 | Austria | 0 | 0 | 0 | 3 |
| 4 | Belgium | 0 | 2 | 2 | 1 |
| 5 | Ireland | 0 | 0 | 0 | 1 |
| 6 | Netherlands | 0 | 0 | 0 | 1 |
| 7 | Spain | 1 | 0 | 1 | 1 |
| 8 | Hungary | 1 | 0 | 0 | 0 |
| 9 | Sweden | 1 | 0 | 0 | 0 |
| 10 | Denmark | 1 | 0 | 0 | 0 |
| Total | 11 | 6 | 14 | 24 |
As seen in the map and table above, at least ten EU countries reported terrorist attacks by jihadist individuals or groups. This data suggests the presence of jihadist groups in these countries, even if through a single attack.
At the same time, the number of arrests related to membership in or inspiration by jihadist groups is reported to be significantly higher than for other groups. In 2024, 289 individuals were arrested across Europe for membership in or connection to jihadist groups. Meanwhile, a total of 449 individuals were arrested on suspicion of terrorist acts related to various extremist groups, with Islamist jihadists accounting for 64.4% of them.
Arrest statistics show that the scope of individuals affiliated with or inspired by Islamist jihadist groups is far broader than the countries where attacks occurred. According to available data, the presence of such individuals is expanding. Below, we examine arrest data broken down by year (2021-2024) and EU member state.
| No. | Country | 2021 | 2022 | 2023 | 2024 |
| 1 | France | 96 | 93 | 62 | 58 |
| 2 | Germany | 24 | 30 | 39 | 37 |
| 3 | Austria | 23 | 16 | 18 | 22 |
| 4 | Belgium | 18 | 22 | 67 | 25 |
| 5 | Ireland | 4 | 4 | 9 | 1 |

As seen in the table and map above, individuals have been arrested in at least 22 out of 27 EU member states. The number of countries on this list has increased from 2021 to 2024, indicating the growing influence of Jihadist groups, both in numbers and geographic reach.
Another serious and important issue visible in the new Europol report is the presence of youth, their individual activities, and their recruitment online. The report highlights examples of individuals aged 14 to 21. This suggests that Islamist terrorist groups increasingly focus on recruiting and misleading teenagers and young adults. Now that this age group has the most access to technology and social media, the risk of vulnerability is greater.
According to the Europol report, in 2024, 80 people were arrested for disseminating jihadist propaganda on social media and in the digital space. The majority of these individuals supported ISIS (including its Khorasan branch, ISKP). Social media networks and messaging apps remained the primary tools for spreading terrorist audio-visual content by radicalized individuals; individuals who were, in many cases, very young and self-radicalized, possessing varying levels of technological skill. These ranged from those only able to repost and share existing content to those capable of producing AI-generated content. This means that Islamist terrorist groups exploit every available capacity to achieve their goals.
Terrorism financing through money transfers is another activity that involves individuals in terrorist groups and facilitates money laundering. A large portion of Europol’s arrests involve individuals accused of financing terrorism. These individuals used various methods to send money to terrorist groups, including Hawala, online transfers to bank accounts, transfers via the VIA system, and digital currency. The most important and most used method in this regard has been the Hawala money transfer system.
The social and political consequences of this evolving threat are vast. Far-right movements use this opportunity to polarize society, push debates on immigration and security to the center of domestic politics, and create a sense of insecurity among citizens. This process can itself become a driver for further radicalization, demonstrating that terrorism is not just a security issue but also a catalyst for political and social change.
In several European countries, some political parties, including far-right parties, generalize the issue of jihadist terrorism to the entire Muslim immigrant community and use it as a political opportunity and a tool to pressure liberal parties and governments. Liberal governments, in turn, to maintain and retain power, attempt to implement a series of changes in laws or even engage with terrorist groups like the Taliban for the forced deportation of individuals who have committed serious crimes, hoping to alleviate domestic political pressure.
Germany, as one of the leading countries in pursuing this policy and engaging with the Taliban, has now become a model for other countries such as Denmark, Austria, Sweden, and the Netherlands. This forced deportation diplomacy has been somewhat effective only domestically in managing the situation in response to political pressure from the right, but it has not led to any reduction in the rate of jihadist radicalization. As the new statistics released by Europol show, from 2022 to 2024, the rate of jihadist attacks has increased by 300%.
My analysis indicates that the Taliban, by continuing an expansionist approach that enables transnational militancy, have effectively created a platform for the West’s forced engagement with the group. The group’s treatment of deportees from Europe illustrates this dual strategy: the official reception at Kabul airport for these individuals with titles like “Mujahid” and “hero” not only shows a lack of criminal deterrence against them but also constitutes a form of legitimization of their security background. Based on observations, none of these individuals have been held in Taliban prisons; instead, they either join the ranks of this group or, with the cooperation of migrant smuggling networks (which mainly operate under the influence or control of Taliban elements), have their identities and documents changed, paving the way for their return to Europe. This cycle creates a serious challenge for the long-term security of European countries.
European policymakers face a serious challenge: how can security be guaranteed without undermining civil liberties and social cohesion They are effectively confronted with this question: security or freedom? Increased controls and restrictions might yield short-term results, but in the long run, they deepen divides and make the threat more complex. A sustainable solution requires a combination of smart security, social policies, and programs to counter radicalization both online and offline.
Europe now stands in the midst of this confrontation: small but smart terrorism, security and media policies that are sometimes themselves crisis-inducing, and political movements that exploit every incident to consolidate power. Success or failure in managing this threat will impact not only security but also the democratic foundations and liberal values of Europe. If the new threat is not properly understood and managed, the result could be more than individual violence and sporadic attacks; it could be a widespread political and social crisis.
The fight against jihadist radicalization is not solely the task of European governments. Muslim communities living in Europe also have an important role to play. They can help prevent the influence of extremist narratives by paying close attention to the educational and cultural content their teenagers and young adults are exposed to. Furthermore, cooperating with security forces and reporting suspicious cases, as well as preventing the activities of preachers who seek to promote violence in the name of religion, are among the important responsibilities of these communities in maintaining social cohesion and collective security.
Finally, it must be acknowledged that Europe’s real danger today lies not in the number of attacks, but in their changing nature and dispersion. The new threat, while small, possesses the ability to generate a massive political, social, and media wave, and every security or political decision must be made with an understanding of this complexity. Europe faces a difficult test; a test whose success will be measured not only in controlling violence but also in preserving European values and political and social cohesion.
