The 19-year-old girl from Maastricht who spent nine months in Syria as a jihadi bride was released from custody on Tuesday afternoon.

The girl, a Muslim convert who adopted the name Aïcha, was being held on suspicion of being a member of a terrorist organisation. She has been given a conditional release but the conditions were not made public.

The court said it had agreed to release the girl after weighing up her personal interests against those of society. If she meets the conditions of her release, there is sufficient guarantee that the official investigation into her case can proceed, the court said.

Aïcha hit the headlines last week when her mother said she had travelled to Syria to rescue her daughter. However, the Dutch public prosecutor later said that the mother had not been in Syria and had probably waited for her daughter on the Turkish-Syrian border.

The girl went to Syria when she was 18 to marry high profile Dutch jihadi Omar Yilmaz. The timing of her release is being kept secret in the girl’s interest, the court said.
