The Brit teen was said to be a member of the barbarous terror group's feared "morality police", who punished those that flouted ISIS laws on how to dress and behave.
Begum, who fled her London home four years ago to join the group, was seen clutching a gun as she yelled at Syrian women in ISIS-stronghold Raqqa for wearing brightly-coloured shoes.
Jihadi bride stereotypes are causing female Isis members to be dangerously underestimated by security services, the United Nations has warned.
结合国告诫说，圣战新娘的呆板印象致使女性ISIS成员被平安部分低估。
In the wake of home secretary Sajid Javid’s decision to strip Shamima Begum of her British nationality, an arm of the UN Security Council said there was an “urgent need” to monitor female jihadis remaining in Iraq and Syria.
In its annual report on terrorism in the European Union, Europol said that while the number of foreign citizens joining Isis was decreasing, women made up an increasingly “significant percentage”.
“An increasing proportion of women have travelled from some EU member states – for example from the UK, Belgium and, more markedly, the Netherlands,” the security agency said. “Women may also seek to radicalise others, take part in on and offline recruitment, and actively finance and facilitate terrorist groups and departure to them.”
