Terrorism risks in Europe to increase in 2018 as Islamic State’s Foreign Fighters return

Terrorism risks in Europe are likely to increase in 2018 as foreign fighters depart the former ‘Caliphate’ in Iraq and Syria and bring their training and expertise back to the continent. That’s according to a new report issued from Jane’s Terrorism and Insurgency Centre by business information provider and analyst IHS Markit.

“In the five-to-ten year outlook, European countries will face an elevated terrorism threat posed by radicalised convicts, returned foreign fighters and other returnees who have direct ties to the legacy of the Islamic State,” explained Otso Iho, senior analyst at Jane’s Terrorism and Insurgency Centre, in conversation with Risk UK.

Growing numbers of Islamist convicts are likely to exacerbate the risk of radicalisation in prisons. Additionally, many of those imprisoned for providing support to groups like the Islamic State in the past two years will probably be released between 2019 and 2023. This is according to data analysed by Jane’s Terrorism and Insurgency Centre.

Key findings of the report

*Islamist militancy will remain the primary terrorism threat in Europe, with international operations becoming increasingly important for the Islamic State as it seeks to maintain its relevance among supporters globally

*Returning foreign fighters will drive an increase in the terrorism threat, and particularly so via the potential transformation of radical Islamist support networks into operational structures directly involved with attack plots

*Though low-capability methods will remain prominent, it’s likely that new and more destructive methods will emerge in the next two years in Europe, including the use of car bombs and the adoption of new technologies such as drones

*Jane’s Terrorism and Insurgency Centre’s analysis of European prison sentencing reveals that, between 2019 and 2023, a substantial number of terrorism convicts who have been active supporters of Islamist militant groups are likely to be released into the general population

*Security Services will struggle to adequately monitor a combination of returning militants, an increased number of radical Islamist networks involved in the propagation of terrorism and the radicalisation risks associated with a substantially increasing Islamist prison population

Violent radicalisation of existing Islamist networks

In addition to the immediate and direct security threat posed by returning foreign fighters, a significant risk is likely to emerge through their potential to transform and radicalise existing Europe-based Islamist networks.

“Foreign fighters are likely to hold substantial credibility in Islamist networks that are already prone to supporting groups like the Islamic State,” added Iho. “Their input and leadership could plausibly move groups that have previously held a supportive role – financing, facilitating travel, spreading propaganda – to adopt an operational one: setting up cells, acquiring weapons, providing facilities and safe houses for explosives building and recruiting militants for attacks in Europe.”

‘Low-capability’ attacks, including crude improvised explosive device (IED) attacks, vehicle-impact attacks using rented or stolen trucks and vans, knife and (in a limited number of cases) small-arms attacks are likely to continue, employed primarily by individuals or small cells.

“Foreign fighters returning to Europe will provide critical skills to help an increasing number of operational Islamist networks conduct more complex attacks,” stated Iho. “These critical skills include the construction of viable IEDs – learned in Iraq and Syria where the Islamic State has produced IEDs on an industrial scale – as well as expertise in assault weapons and the use of new weapons types or technologies such as drones.”

The successful use of car bombs or suicide attack car bombs by Islamist militants on European soil would mark a notable increase in the threat level. There are indicators that some cells have already attempted to adopt this method, including the perpetrators of the August 2017 terrorist attack in Barcelona.

Returned militants will increase the likelihood of the successful execution of such an attack due to relevant skills learned within the Islamic State’s ‘Caliphate’.

Counter-terrorism challenges

As stated, Jane’s Terrorism and Insurgency Centre’s analysis of European prison sentencing reveals that, between 2019 and 2023, a substantial number of terrorism convicts who’ve been active supporters of Islamist militant groups, but in most cases haven’t taken action to plot or conduct attacks in-country, will be released from prison. As foreign fighters return and militant Islamist activity continues, this trend is likely to accelerate.

Since the 2015 attacks in Paris, counter-terrorism legislation across Europe has been harmonised pretty substantially. On a legislative level most countries are equipped to deal with returnees in a ‘hard’ manner (ie by imprisoning those who have committed terrorism offences or who pose a clear security risk). In practice, however, enforcement of these laws varies somewhat from country to country based on their experience of terrorism. Countries such as the Nordics, which have had lower terrorism exposure, tend to have more lenient sentencing.

“Though it’s too early to make definitive conclusions based on available data of returned foreign fighters, harsh sentencing practices in host countries don’t necessarily appear to be a significant disincentive for foreign fighters returning from Iraq and Syria,” concluded Iho. “The UK is an example of this trend. Despite ample precedent and prison sentences for returnees, the UK has the highest number of returned militants in Europe with around half having come back. For those returnees planning on engaging in violence, the symbolic target value of Western European countries perhaps outweighs the higher likelihood of being apprehended and imprisoned.”
