The article states: “South Africa is attractive for ISIS recruitment for a number of reasons. South African recruits seem more likely to come from average-income families, which reduces the financial burden their recruitment would otherwise pose.”

“Most of the recruits could therefore take care of their own travel arrangements, though some still require financial and technical support. Travelling on a South African passport does not raise immediate suspicion, which makes it easy for South Africans to book itineraries that would be less accessible to passport holders from other African countries.”
