The UK's Home Secretary says a British teenager, who travelled to Syria while a schoolgirl to join the IS terror group, could be prevented from returning to Britain.
Nineteen-year-old Shamima Begum says she wants to return to the UK to have a baby she's expecting.
But she also says she has no regrets about fleeing Britain to join the IS.
Home Secretary Sajid Javid says she could be stopped from returning, or prosecuted if she does.
But former British Commander in Afghanistan Colonel Richard Kemp says the UK system is not set up like that of the United States to deal with returnees who've been radicalised.
