Check out my new ‘Insight’ for the International Centre for the Study of Radicalisation: "Up to 11,000 Foreign Fighters in Syria; Steep Rise Among Western Europeans"

Since ICSR published its first estimate in April, the issue of foreign fighters in Syria has become a major concern for Western governments. More reports have emerged since, though few have accurately gauged the full extent and evolution of the phenomenon.
This ICSR Insight provides an update of our April estimate, offering the most comprehensive and richly resourced account of the Syrian foreign fighter phenomenon from open sources. Based on more than 1,500 sources, we estimate that up to 11,000 individuals from 74 nations have become opposition fighters in Syria – nearly double our previous estimate. Among Western Europeans, the number has more than tripled from (up to) 600 in April to 1,900 now.
