Of those, it had been estimated that around 30% had already returned to their home countries by 2018.

The issue of foreign fighters had been high on the political agenda at both Member State and EU level for the last five years and touched upon a wide range of policies:

+ policies related to the prevention of radicalisation
+ to information exchange at EU level
+ to criminal justice responses to returnees
+ to disengagement/deradicalisation inside and outside prisons.

This study aimed at outlining the EU response to the issue of returning foreign fighters and their families. It furthermore examined how six Member States have responded to this phenomenon so far (Belgium, Denmark, Germany, France, the Netherlands and the UK).

These Member States were confronted with significant challenges in dealing with foreign fighters that combined legal, ethical and practical questions regarding their obligations and capabilities as regards the handling of the foreign fighters still abroad and the returnees already on EU soil. Meanwhile, Member States' existing programmes aiming at tackling radicalisation were difficult to evaluate, leading to uncertainties as regards the efficiency of current practices.
