She appears pale, afraid and covered in dust, unveiled but wearing a colourful scarf around her neck.

She was initially mistaken for a kidnapped Yazidi girl because of her lack of Arabic.

Linda was reported missing from her home a year ago, where she had been living with her mother, Katharina, and step-father, Thomas.

She grew up in a Protestant family, and had not showed any interest in religion until a few months before her disappearance. In the spring of 2016 she told her parents for the first time that she was interested in Islam.

Friends in Pulsnitz say she converted to Islam around this time and was radicalised online in chat rooms. She started learning Arabic, taking the Koran to school, wearing conservative clothing and becoming fascinated with Islam before her disappearance.
