Why do young people from Europe head off to fight in a religious war? How do they become radicalised? These questions have been prompted by reports that more than four hundred young Moslems from Germany have traveled to Syria and Iraq in recent months to fight in the ranks of terrorist groups. The intelligence services are warning that any who return to Europe could pose a threat to the public.

How serious is the threat from these re-imported terrorists? Is it appropriate to tighten up anti-terror laws. What should Europe do in the face of this perceived danger?
