MAASTRICHT, Netherlands: A blonde, blue-eyed Dutch teenager from a Catholic family who was rescued by her mother after marrying an Islamic State fighter in Syria appeared in court Friday. She was ordered by the court to be detained pending possible terror charges.

“Today the examining judge has reviewed the custody order of Aicha and concluded that it was lawful,” court spokesman Marc Bax told journalists after the hearing.

Another hearing on Tuesday will decide if the young woman, known as Sterlina before she adopted an Arab name, should be held for another 14 days and possibly charged.

Nineteen-year-old Aicha arrived in the Netherlands on Wednesday with her mother Monique after going to Syria in February to marry an IS fighter she saw as a Robin Hood figure.

Annemarie Kemp, a spokeswoman for the public prosecutor’s office, told AFP earlier Aicha had been arrested “on suspicion of crimes threatening state security.”

European nations are increasingly concerned about returning jihadist fighters, but the question of what to do with women who travel to Iraq and Syria but do not fight is a thorny one. The authorities have barred Monique and Aicha’s lawyers from talking to the press because of the sensitivity of the case.

But Monique, 49, has previously spoken at length to Dutch media about her daughter, previously known as Sterlina before adopting an Arab name, who “liked going out, playing the piano and listening to music.” She told Dutch television that her daughter converted to Islam and began wearing a face-covering niqab. The turning point came when Aicha saw an interview on Dutch television with a Dutch-Turkish jihadist fighter, Omar Yilmaz.

Yilmaz, a former soldier in the Dutch army who also did national service in Turkey, is one of a group of Dutch jihadists who have traveled to Syria where he is training fighters for the IS group.
