A short UK article that starts with:
Young British Muslims whose families have lived in the UK for generations are more at risk of radicalisation than recent migrants to Britain, according to new research which reveals the common characteristics of those most vulnerable to recruitment by terrorists.

Suffering from depression, being financially comfortable and being socially isolated were also common factors amongst those sympathising with terrorism, the University of London study found.
The author is Professor Kamaldeep Bhui, lead author of the study and professor of cultural psychiatry and epidemiology at Queen Mary University of London said:
The relationship between radicalisation and mental health is complex but we now know depression, alongside poor social networks and isolation, does play a role in vulnerability to radicalisation.
