Two women, Hoda Muthana and Shamima Begum, from the United States and Britain respectively, left for Syria, married Islamic State in Iraq and Syria (ISIS) fighters, had children, and now seek to return to their home countries with their children.

However, they both are barred from doing so - though for different reasons: Begum has been deprived of her British citizenship, while US Secretary of State Mike Pompeo claims that Muthana was never a US citizen, having been born to a foreign diplomat in the US.
