Most 'Islamic State' fighters recruited by friends, terror expert says

Three-quarters of those who become foreign fighters for the Islamic State extremist group are recruited through friends and 20% by family members, a terrorism expert said.
Scott Atran, co-founder of the Centre for the Resolution of Intractable Conflict at Oxford University, said research has found that “radicalisation rarely occurs in mosques” and very seldom through anonymous recruiters and strangers.
