Shamima Begum said she was a "dumb kid" when she fled the UK to join ISIS, and has again expressed her desire to return to the UK.
The 21-year-old fled Bethnal Green to join ISIS as a schoolgirl six years ago, and has since had her British citizenship revoked.
In an interview with the Daily Mail, Begum said: "I don’t think I was a terrorist. I think I was just a dumb kid who made one mistake.
“I personally don’t think that I need to be rehabilitated, but I would want to help other people be rehabilitated. I would love to help.”
Dressed in modern western clothes, with a Nike baseball cap, lipstick and large sunglasses, Begum was asked why she had stopped wearing traditional Islamic dress.
She said: "I wear these clothes, and I don’t wear a hijab, because it makes me happy. And anything in this camp that makes me happy is like a lifesaver.”
Begum was 15 when she and two other east London schoolgirls travelled to Syria in February 2015. She married an ISIS fighter when out in Syria. She has since been arrested and is currently detained in the Al-Roj camp run by the Syrian Democratic Forces.
She has repeatedly made calls to be admitted back into the UK, but lost her recent legal battle after the Supreme Court ruled in the Home Office's favour.
