(JTA) — Among the some 100 girls and young women who have left France in recent weeks to join the ISIS in Syria was a Jewish girl, the Daily Mail reported citing French intelligence.

The French security official, who spoke anonymously to the British newspaper, did not provide any other details on the Jewish girl, such as her age and how she made her way to Syria.

The decision of the girls to join ISIS and their actual departure come after months of recruitment, mostly on-line, targeting adolescents, according to the Daily Mail. The girls serve as wives, babysitters and housekeepers for jihadists.

Between 20 and 50 young girls have also come to Syria to join ISIS from Britain, according to the newspaper.
