Dozens of Australian women 'supporting terrorism'

Up to 40 Australian women have taken part in terror attacks or are supporting militant groups, Foreign Minister Julie Bishop has said.

She said an increasing number of women were going to Syria and Iraq to join husbands fighting with Islamic State (IS) or to marry a militant.

Dozens of Australian nationals are thought to have joined IS.

Australian officials are worried about the effect of returnees, and on those who support them, on domestic security.
