The number of foreign fighters in Iraq and Syria has more than doubled since last year to at least 27,000, according to a new report by an intelligence consultancy, highlighting the global dimension of the conflict.  The figures, compiled by the Soufan Group, indicate that efforts by countries around the world to stem the flow of foreign fighters to Iraq and Syria and blunt the appeal of violent organisations such as Islamic State (Isis) appear to have made little impact.

The largest number travelled to the two countries, across which Isis controls a swath of territory, from the Middle East and the Maghreb, with about 8,000 foreign fighters each.  Around 5,000 made their way from Europe, with a further 4,700 from former Soviet republics.  The Soufan Group added that between 20 and 30% of foreign fighters were returning to their home countries, creating major challenges for domestic security agencies as Isis in particular looks to carry out an increasing number of attacks overseas.  Isis claimed responsibility for a massive attack in Paris last month that left 130 dead, and its fighters have been held responsible for violence in a litany of countries ranging from Iraq to Bangladesh.  The threat of returning foreign fighters has sparked widespread debate, particularly in western countries, many of which have criminalised travel to Syria to fight in the country’s years-long conflict.  In the wake of the Paris attacks, US lawmakers have also called into question a programme that allows Europeans to travel to the United States without a visa.  But, according to the Soufan Group, the latest figures are “evidence that efforts to contain the flow of foreign recruits to extremist groups in Syria and Iraq have had limited impact”.

Isis seized control of significant parts of Syria and Iraq last year, declaring a self-styled Islamic “caliphate” and committing widespread atrocities.  It has sought to recruit followers via social media, prompting growing alarm in the west, with the European Union launching a forum this month to bring together internet giants like Google and Facebook as well as law enforcement agencies to combat online extremism.  The Soufan Group noted, however, that “while the power of the Islamic State’s social media outreach is undeniable, it appears more often to prepare the ground for persuasion, rather than to force the decision”.  “As hotbeds develop, recruitment through social media becomes less important than via direct human contact, as clusters of friends and neighbours persuade each other to travel separately or together to join the Islamic State.  “Even if the Islamic State is a failing enterprise in steady decline, it will be able to influence the actions of its adherents, and it may become more dangerous as it dies.”
The Soufan Group finds 27,000 from 86 countries drawn to Isis territory, suggesting international efforts to stem flow are ineffective
