Belgian fighters in Syria & Iraq – an important review of our data
After a thorough review of our data, we do estimate the total number of Belgian foreign fighters who were active at some point in the current Syrian-Iraqi at 543 individuals now. Almost 70% of them have joined Islamic State, while Shariah4Belgium and the so-called Zerkani network remain the most important recruiters. 127 people have returned to Belgium, while at least 105 were reportedly killed.
We have been keeping track of Belgian foreign fighters for several years now, and we felt that a review of our data was needed. At the time of our very first publication, most of the information was vague and much records in our database lacked sufficient identification.
While adding details, the risk of double counting grew. We are pretty confident that the number of fighters not discovered yet, greatly compensated for that. But with all the sources we have now — both publicly available as confidential ones — we thought it would be wise to omit as much of potential doubles as possible.
Therefore, we have reviewed every single entry in our database, investigating the chance that the same person occurred elsewhere. Apart from a rather small number of obvious cases, we finally decided to omit an even number of completely anonymous records dating from before 2014 as the number of fighters we know in detail who had left already at that same time. That is a rather arbitrary measure, but we do believe that it helps to make our estimate more accurate.
On the other hand, we added all the information that we have about minors taken to the battlefield, records that we previously didn’t count. It can be feared that the foreign fighters phenomenon will last for many years, and while the minors of today probably will be the fighters of tomorrow, it becomes relevant now to count them in.
Definition of Belgian fighters
Altogether, we do estimate the number of Belgian foreign fighters in the current Syrian-Iraqi conflict at 543 now, defining them as follows:
1) every person of Belgian origin, foreign origin but living in Belgium for a significant time, or clearly recruited by an entity operating from Belgium and departed to the conflict zone via Belgian soil;
2) having at least physically tried to reach the war zone of the Syrian-Iraqi conflict that started in March 2011;
3) with a clear intention to join a local fighting party there, be it as a fighter themselves or in any other role.
While it has to be stressed that this definition is broader than Sunni Islamists, actually 534 (or 98% of all our records) can be considered as such. Other kind of affiliations, such as pro-regime fighters in both Syria and Iraq, certainly are a very small part of the foreign figher phenomenon in reality too. But they are also underrepresented in our database because the focus of our active investigations is the Sunni Islamist part.
In the near future, we may try to get a clearer picture of those other kind of affiliations too. More specifically, we would like to add figures about Kurdish fighters, who aren’t included at all for the moment, although we know for sure that they too have Belgian fighters in their ranks. Another possible extension of our database could be the Belgian foreign fighters who have joined Islamic State in Libya.
Our count versus the official one
Although our total estimate is considerably lowered by the review, it is still higher than the number of 458 mentioned by Interior Minister Jan Jambon in April of this year. Probably, authorities do limit their number to fully identified and thus juridically relevant cases, while our database also includes anonymous cases for which the source was deemed reliable. But with much more limited means, we still identified 324 individuals with their full names.
Of all the people in our database, 493 have reached the battle zone — a rate of 90.8%. 32 or 5.9% were stopped somewhere abroad, and 18 or 3.3% before they left the Belgian soil. We have information about 127 people who returned to Belgium — which is slightly higher than the official figures of 114 à 117 mentioned recently. 401 of our records are males, representing 74%. 64 or 12% are females, while the gender is not known for another 78 or 14%.
We have information about 27 children taken to the war zone as minors, of whom at least 18 male and 6 female. These numbers do exclude however youngsters who were juridically still minors at their moment of departure, but apparently have left at their own will. According to official sources, there are at least 48 Belgian minors who have left, of whom 32 were younger than twelve.
Islamic State by far the most important group
217 people in our database joined the Islamic State. That is 67.4% of all 322 records for which an exact affiliation is known. Jabhat an-Nusra, the Syrian branch of the global terrorist network al-Qaeda that has rebranded itself into Jabhat Fath as-Sham very recently to indicate a split from al-Qaeda, is the second most important group with 43 people for whom it is their last known affiliation.
It must be noted that affiliations often changed in course of time. The third most important group for instance, Majlis Shura al-Mujahideen, became a part of the Islamic State early in 2013. Until then, it was the group joined by almost all the recruits of Shariah4Belgium. Some of them followed their leaders into the Islamic State immediately, while a significant number of others initially switched side to Jabhat an-Nusra. 33 people are still listed in our database with Majlis Shura al-Mujahideen as last known affiliation, because we do not know in which group they landed. But the total number of Belgians who have belonged to Majlis Shura al-Mujahideen at a certain point amounts to 77.
Other Sunni Islamist groups with Belgians in their ranks are Suqur as-Sham (joined by the notorious Brussels based cheikh Bassam Ayachi, and merged in March of last year with Ahrar as-Sham) with 13 people; Katibat al-Khadra and the so-called Katibat des Français with two individuals; and Faylaq as-Sham, Jabhat Ansar al-Din, Jaysh Muhammad, Jund al-Aqsa, Katibat al-Muhajiroun and the Turkistan Islamic Party with each one.
Shariah4Belgium & Zerkani network main recruiters
Looking at recruitment organizations, the Antwerp based Shariah4Belgium still is the most important one. 97 people were at least in touch with that organization before their departure. Second comes the network around the Brussels recruiter Khalid Zerkani, with 72 individuals. An overlap exists, mainly in the circles of the Brussels recruiter Jean-Louis Denis. He worked together with both networks, and has influenced at least 55 people who tried or succeeded to reach the battle zone. The Centre Islamique Belge of the mentioned Bassam Ayachi had proven ties with four fighters, while the so-called ‘Terloplein Group’ and ‘The Way of Life’ — both of which can be considered as spin-offs of Shariah4Belgium — had ties with respectively five and one who’ve tried.
Geographically, the Brussels Capital Region has the highest number of Belgian foreign fighters with 179 individuals on a total of 403 for whom the origin is known, including at least 40 from the now notorious municipality of Molenbeek-Saint-Jean. Antwerp is the second most important place of origin with 98 people, while Vilvoorde (29) and Mechelen (17) add to the importance of the axis Brussels-Antwerp as hotbed of the Belgian jihad.
105 deaths, of whom 11 by suicide attacks
Of the Belgian foreign fighers in our database, 105 were reportedly killed. For nine of them, that happened after their return to Europe to commit a terrorist attack: Khalid Ben Larbi and Soufiane Amghar during a police operation on January 15, 2015 in Verviers (Belgium); Bilal Hadfi and Ibrahim Abdeslam while conducting suicide attacks on November 13, 2015 in Paris (France); Abdelhamid Abaaoud and Chakib Akrouh during a police operation following the Paris attacks on November 18, 2015 in Saint-Denis (France); Mohamed Aziz Belkaïd during a police operation on March 15, 2016 in Forest (Belgium); and Najim Laachraoui and Ibrahim El Bakraoui while conducting suicide attacks on March 22, 2016 in Brussels (Belgium).
It has to be stressed that the death of 96 others in the war zone cannot be verified. There are for instance several cases known already of foreign fighters faking their death to lure security services, including the already mentioned Abdelhamid Abaaoud prior to the Verviers plot and the Paris attacks. So, being mentioned in the list of people killed we publish beneath, only means that relevant sources have announced the death of that person, without clear signs that it was inaccurate. Altogether, 11 Belgian fighters have died while committing suicide attacks: six in Iraq, two in France, two in Belgium and one in Syria.
