Radical Islamic preachers have increasing influence on the education of young Muslims in the Netherlands, according to the annual report of the Dutch security service AIVD which was published on Tuesday.

Some of these preachers, particularly those involved in private Islamic education centres, have ‘double standards’ about the use of violence and are potentially feeding jihadism, the report states.

While after-school lessons in Arabic and Islam would appear to be ‘low-threshold and innocent’, ‘we believe that children and young adults are being alienated from society and may be hindered from participating,’ the AIVD said.

Last month the AIVD warned Amsterdam mayor Femke Halsema that directors of the city’s only Islamic secondary school had links to a Chechen terrorist group and said that a radical British imam had held secret meetings at the school and that there was considerable ‘Salafist’ influence.
