Hundreds of young women and girls are leaving their homes in western countries to join Islamic fighters in the Middle East, causing increasing concern among counter-terrorism investigators.
Girls as young as 14 or 15 are travelling mainly to Syria to marry jihadis, bear their children and join communities of fighters, with a small number taking up arms. Many are recruited via social media.
Women and girls appear to make up about 10% of those leaving Europe, North America and Australia to link up with jihadi groups, including Islamic State (Isis). France has the highest number of female jihadi recruits, with 63 in the region ”“ about 25% of the total ”“ and at least another 60 believed to be considering the move.
