A German teenage girl has said she was an “idiot” for joining Islamic State and the decision has wrecked her future, in her first interview since her arrest by Iraqi forces in Mosul.

Linda Wenzel, 17, claimed her escape was a “stupid idea” but showed little remorse in the first meeting with her family since she left her hometown of Pulsnitz in Saxony for Syria in July last year.

Linda was briefly reunited with her mother Katharina and sister Miriam, who were allowed to visit her at the Palace of Justice in the Iraqi capital of Baghdad.

A video of the meeting shows Linda, who is currently being held in prison while she awaits trial, wearing a flowery headscarf sporting round cheeks. She appears hesitant at first and pauses for a few seconds before finally embracing her mother, who hands her a stuffed toy.
