hamima Begum, one of three teenage girls to flee east London for a new life with the Islamic State group, says she has given birth to a baby boy.
Ms Begum left four years ago aged 15. Found in a Syrian refugee camp last week, she now hopes to return home.
The 19-year-old told Sky News: "People should have sympathy towards me for everything I've been through."
Under international law, the UK is obliged to let a Briton without the claim to another nationality back in.
Asked if she had made a mistake by travelling to Syria, Ms Begum
told Sky News: "In a way, yes, but I don't regret it because it's changed me as a person.
"It's made me stronger, tougher. I married my husband. I wouldn't have found someone like him back in the UK."
She continued: "I had my kids, I did have a good time there.
"It's just that then things got harder and I couldn't take it anymore."
