The 18-year-old Moroccan girl was arrested in Gandia, near Valencia, after being detained by counter-terror police. She was Moroccan but had lived in Spain for years.

Police confiscates boxes of evidence from inside her home. Police says at the time of her arrest, the woman 'was making the last preparations for her journey' to Syria, a police statement said.

She was the latest in a series of suspected ISIS sympathizers detained in Spain in the last year, with another woman arrested on the island of Lanzarote for allegedly recruiting women and girls for ISIS in July.
