Politically motivated assaults, performed through lone folks missing direct association with any terrorist organization, have transform extra not unusual in Europe all the way through the previous couple of a long time.
Probably the most not unusual and devastating types of lone-actor violence comes to using into crowds. In 2016, Mohamed Lahouaiej-Bouhlel used this option to kill 86 other folks in Great. In 2011, Anders Breivik detonated a bomb in central Oslo prior to sporting out a mass taking pictures at the island of Utøya, leaving 77 lifeless. Now not all lone-actor assaults are as fatal or indiscriminate as those. Some goal explicit other folks, as observed within the assassinations of German flesh presser Walter Lübcke in 2019 and British MP David Amess in 2021.
Lone-actor terrorism – sometimes called lone-wolf terrorism – poses a novel problem for Eu states. Conventional counterterrorism gear designed for organised teams like al-Qaeda, Islamic State, or Eta are a ways much less efficient towards other folks performing on my own. Whilst lone-actor plots are normally much less complicated, they may be able to nonetheless reason vital hurt.
We’ve additionally observed that lone-actor assaults can cause far-reaching ripple results. The ensuing public outrage can accentuate debates on contentious problems like immigration, and in the long run spice up reinforce for extremist events.
Copycat or reactionary assaults are any other outcome of lone-actor terrorism. A putting instance is the mass shootings performed through Brenton Tarrant in New Zealand in 2019. He cited the movements of Breivik and others as direct inspiration. In line with Tarrant’s personal manifesto, a key cause for his radicalisation used to be the 2017 Islamist assault in Stockholm, the place Rakhmat Akilov, an asylum seeker from Uzbekistan, drove a truck right into a crowd, killing 5 other folks, together with an 11-year-old kid.
Why lone-actor assaults are so tough to forestall
As a result of lone actors perform independently and seldom be in contact their intentions, their identities continuously stay unknown till after an assault. Their targets and ideologies are ceaselessly ambiguous, making it exhausting to are expecting behaviour or make a choice most likely objectives. Even as it should be figuring out an incident as lone-actor terrorism can also be difficult.
The case of Axel Rudakubana illustrates this issue. Rudakubana killed 3 younger women in Southport, northern England, in 2024 after breaking into their Taylor Swift-themed dance workshop. Regardless of the invention of an Al-Qaeda coaching handbook in his ownership, prosecutors discovered no really extensive proof of political motivation and labelled the incident a “mass killing” somewhat than terrorism.
It is rather tough – if no longer not possible – to decide the precise choice of lone-actor terrorist assaults that experience taken position in Europe with walk in the park. The absence of a universally approved definition of terrorism is a part of the issue. It’s additionally imaginable that acts of mass violence are being categorised as terrorism when they’re in reality ideologically impartial. Similarly, it may be tough to decide whether or not an actor actually acted on my own, particularly in an age of web radicalisation.
What is apparent is that unbiased terrorist assaults changed into extra widespread within the early 2010s. By means of 2013, such incidents spiked, with Europe seeing six to seven Islamist and far-right assaults in step with yr (up from fewer than one yearly prior to 2010). Those figures refer strictly to instances the place perpetrators acted independently, apart from the ones with proof of exterior reinforce. As an example, Anis Amri’s 2016 truck assault in Berlin and Taimour al-Abdaly’s 2010 suicide strive in Stockholm have been first of all observed as lone-actor occasions, however later investigations printed ties to Islamist cells.
Lone-actor terrorism seems much less not unusual amongst far-left and ethno-nationalist teams, although exceptions do exist.

This shift against lone-actor assaults is most likely a results of evolving counterterrorism methods carried out after primary assaults just like the 2004 Madrid teach bombings and the 2005 London bombings. It changed into more difficult to hold out large-scale plots so teams like Al-Qaeda and later Islamic State switched to encouraging or setting up assaults through loosely affiliated folks performing independently however on their behalf.
The fight between terrorist teams and governments is considered one of consistent adaptation. By means of 2018, Europol knowledge indicated that the entire Islamist assaults that have been observed thru to of completion in Europe all the way through that yr have been performed through lone actors.
Lone-actor assaults have a good longer historical past inside far-right terrorism. The time period “lone-wolf terrorist” used to be first popularised in American white supremacist propaganda within the early Nineties – smartly prior to the extra impartial time period “lone-actor terrorist” used to be followed through researchers. As counterterrorism efforts an increasing number of focused white supremacist teams, many inside the motion got here to peer unbiased motion as top-of-the-line strategy to evade detection and handle operational secrecy.
Addressing the risk
Thankfully, we now perceive extra about lone-actor crimes. We’ve come to remember that those assaults stem from complicated mental and environmental components.
Whilst perpetrators shouldn’t be disregarded as merely “crazy,” psychological well being can play a task in radicalisation, particularly when blended with non-public grievances, failed aspirations, and perceived injustices. Influences from circle of relatives, friends and on-line areas additionally form this procedure. Whilst no two radicalisation pathways are equivalent, sure patterns can also be noticed – and recognising them early might assist cut back the risk.
The theory of “self-radicalisation” additionally deserves warning. Lone actors infrequently radicalise in isolation; their manifestos continuously echo broader ideological subject matters, formed through conspiracy theories or charismatic figures. Those actors continuously assign symbolic which means to their movements. Elevating consciousness of the affect of violent public discourse is vital – although this should be performed with out infringing on loose speech. Historical past presentations that offering “pressure valves” for arguable concepts is extra positive than censorship.
Lone-actor assaults are, partially, tough to forestall exactly as a result of they aren’t a systemic risk in the way in which that coordinated, group-based terrorism can also be. Its threat lies in remoted bursts of violence somewhat than in sustained campaigns. However there are patterns price following that would assist save you long term incidents.
