From HSToday:

A group of Muslim female Islamic State (ISIS) “Jihad Janes” who’ve been in Syria off and on – including a prominent member believed to be Um Abdullatif, the widow of Australian fighter Mahmoud Abdullatif — are part of an ISIS female brigade called “Al Khansaa” — whose membership some counterterrorism officials believe could number in the hundreds — have formed a clique of female ISIS members from English-speaking countries based in Raqqah — the Islamic State’s Syrian stronghold. The largely Western women in this clique are believed to be the wives and widows of ISIS fighters.
