British teenager Shamima Begum, who joined the so-called Islamic State when she was 15, has said she regrets speaking to the media and wishes she had found a different way to contact her family.

Ms Begum said she wants to return to the UK with her newborn son.

The now 19-year-old, who has had her British citizenship revoked, was one of three schoolgirls to leave Bethnal Green in London to join the terror group in 2015 and resurfaced heavily pregnant at a Syrian refugee camp last week.

Speaking to the Sunday Telegraph from the al-Hol camp in Syria, Ms Begum said: "They are making an example of me. I regret speaking to the media. I wish I had stayed low and found a different way to contact my family. That's why I spoke to the newspaper."

British Home Secretary Sajid Javid revoked Ms Begum's British citizenship in a move only permissible under international law if it does not leave the individual stateless.

It was speculated that Ms Begum, who is of Bangladeshi heritage, may have citizenship there but Bangladesh's minister of state for foreign affairs has denied this.

Her family have written to the Home Secretary asking for his help to bring her son to Britain.

The letter to Mr Javid said the baby boy was a "true innocent" who should not "lose the privilege of being raised in the safety of this country".

The family said they have had no contact with Ms Begum and had only learned she had given birth to a boy through media reports.

They made clear that they were "shocked and appalled" at the "vile comments" Ms Begum had recently made to the media.
