Foreign Fighters

Welcome to the Foreign Fighters Tab of the International Crimes Database (ICD). This Tab, which is maintained by the T.M.C. Asser Instituut and sponsored by the International Centre for Counter-Terrorism – The Hague (ICCT), will collect cases of (individuals related to) (potential) foreign fighters, who could be defined as “individuals, driven mainly by ideology, religion and/or kinship, who leave their country of origin or their country of habitual residence to join a party engaged in an armed conflict” (A. de Guttry, F. Capone and C. Paulussen, ‘Introduction’, in: A. de Guttry, F. Capone and C. Paulussen (eds.), Foreign Fighters under International Law and Beyond, T.M.C. Asser Press/Springer Verlag (2016), p. 2.)

Often, the topic of foreign fighters is looked at from a (limited) counter-terrorism perspective only. In those cases, the object is not foreign fighters as such, but foreign terrorist fighters. This term has been defined in several ways, but the most authoritative one can be found in UN Security Council Resolution 2178 of September 2014, which refers to “individuals who travel to a State other than their States of residence or nationality for the purpose of the perpetration, planning, or preparation of, or participation in, terrorist acts or the providing or receiving of terrorist training, including in connection with armed conflict”.

Conversely, this Tab will collect cases of (individuals related to) (potential) foreign fighters as such, whether the suspects are charged with terrorism-related crimes (which admittedly will often be the case), war crimes or any other crimes.

Through the analysis of these cases, policy makers, practitioners and scholars alike will get a better insight into how (individuals related to) (potential) foreign fighters are prosecuted and which lessons learned can be distilled from these prosecutions. These lessons will be incorporated in papers that will be placed on both the ICCT website and this ICD Foreign Fighters Tab.

The first paper, based in part on the ICD case summaries, as well as other sources, is entitled ‘Prosecuting (Potential) Foreign Fighters: Legislative and Practical Challenges’ and is authored by Christophe Paulussen and Kate Pitcher. It can be found here.

The second paper is entitled ‘The Prosecution of Foreign Fighters under International Humanitarian Law: Misconceptions and Opportunities’ and is authored by Christophe Paulussen, Hanne Cuyckens and Katharine Fortin. It can be found here.

The Foreign Fighters Tab has just been launched and hence the number of cases is still limited. However, more cases will be uploaded in the future.

Though the ICD is managed by a competent team of editors and interns, and already contains, in addition to several videos and working papers, more than 700 cases, any help would be greatly appreciated. We kindly request that you send suggestions for the database, information regarding important cases from any jurisdiction (not necessarily related foreign fighters), and particularly original court documents to the editors: editors@internationalcrimesdatabase.org.

Thank you very much in advance for your assistance in continuing to build a comprehensive and user-friendly ICD together.

United States of America v. Tairod Nathan Webster Pugh

Jury Verdict, 9 Mar 2016, United States District Court for the Eastern District of New York, United States

Tairod Pugh is an US citizen and a US Air Force veteran who was convicted for providing material support to a terrorist organisation by attempting to travel to Syria in order to join ISIL, and obstruction of justice. After having worked in the Middle East for more than a year as an airplane mechanics, Pugh attempted to reach Syria through Turkey. On 10 January 2015, the defendant took a plane from Cairo and landed in Istanbul airport. As he refused a search of his laptop by the Turkish authorities, he was denied entry and was sent back to Cairo. Upon his arrival, he was detained by the Egyptian authorities who found damaged electronic devices in Pugh’s possession. On 15 January, he was deported from Egypt to the US and was arrested the following day in New Jersey. Pugh’s conviction is the first one after a trial by jury in the US involving an individual who attempted to travel to Syria to join ISIL. On 31 May 2017, he was sentenced to 35 years in prison.   


United States of America v. Mufid A. Elfgeeh

Plea Agreement, 17 Dec 2015, District Court for the Western District of New York, United States

The District Court for the Western District of New York has accepted a guilty plea by Mr. Mufid Elfgeeh and subsequently sentenced him to 22.5 years’ imprisonment for his role in encouraging support for IS, recruiting individuals to fight in Syria and providing financial assistance to those attempting to fight for the terrorist group. Mr. Elfgeeh pleaded guilty to part of the original charges laid against him on 17 December 2015 following his arrest in May 2014. The court records demonstrate that Mr. Elfgeeh had been trying to recruit FBI informants and that his activities had been monitored for a significant period of time prior to his arrest. 


Prosecutor v. Imane B. et al. : Prosecutor v. Imane B. et al.

Judgment, 10 Dec 2015, District Court of The Hague, The Netherlands

In the ‘Context’ case, a large terrorism case in the Netherlands, nine individuals were found guilty of various terrorism offences, ranging from online incitement to the recruitment of individuals to travel to Syria. This case arose out of investigations into the flow of foreign fighters from the Netherlands – namely people heading to Syria in order to join various terrorist groups, including ISIS and al-Nusra. The prosecution successfully argued that an organisation existed in the Netherlands that aimed at recruiting other people to support terrorist groups in Syria and to travel to join the fighting. The case also looked into the use of social media, such as Twitter and Facebook, and its role in recruiting individuals.

The nine accused, including several individuals who had travelled to Syria, faced charges concerning incitement to join terrorist groups, the dissemination of inciting materials, the recruitment of people to travel to Syria, the participation in training to commit terrorist crimes, participation in a criminal and terrorist organisation, and other charges relating to inciting hate and defamation. The defendants were all convicted of differing offences and their sentences ranged from seven days’ to six years’ imprisonment. 


R. v. Sarwar (Yusuf): Yusuf Sarwar, Mohammed Ahmed v. Regina

Appeal Judgment, 9 Dec 2015, Court of Appeal (Criminal Division), Great Britain (UK)

Sarwar and Ahmed travelled from the UK to Turkey and then Syria on 15 May 2013. Both had been in communications on social media with a number of figures discussing jihad and their plans to travel to Syria. They deceived their parents as to the purpose of their trip, which, in reality, was to become involved with anti-Assad forces. After their departure, Sarwar’s mother found a letter from him saying he planned to join Jabhat al-Nusra in Syria, and his parents then told the police.

Sarwar and Ahmed were arrested when they returned to the UK on 13 January 2014. A search of Sarwar’s luggage found over 1600 deleted pictures including those of Sarwar and Ahmed in combat zones and pictures of explosives being made. Both pled guilty to the offense of preparation of terrorist acts contrary to section 5(1) of the Terrorism Act 2006 and were sentenced to 17 years and 8 months in prison. Sarwar and Ahmed appealed the decision.

Sarwar and Ahmed claimed that once they arrived in Syria, they disassociated themselves from combat activities and offered humanitarian assistance.  The Court found that while there was sustained preparation and travel, the trial court judge reached an incorrect conclusion on their involvement in combat activity. Therefore, sentences were reduced to 15 years and 3 months.


Hamza B et al.: Federal Prosecutor v Hamza B, Harris C-K, Abdelfattah A, Younnes HA, Kamal A and Sami L

Judgement, 6 Nov 2015, Tribunal de Première Instance Francophone de Bruxelles, Belgium

On 6 November, a Belgian Court handed down its judgment in a case concerning five foreign fighters and another individual who assisted the fighters travelling from Belgium. The foreign fighters had travelled to Somalia or Syria where they had joined jihadist groups, including Al-Shabab and Jabhat al Nusra. One of the accused, Kamal A, is thought to still be fighting in Syria with Jabhat al Nusra and another, Sami L, is believed to have died while carrying out a suicide attack in Iraq. The defendants received sentences ranging from 3 to 10 years’ imprisonment for having participated in the activities of a terrorist group via their various actions of support, assistance or actual fighting in the conflict.
