For decades women have been involved in terrorism, whether carrying out attacks or supporting organisations. They have been victims of terrorist acts, and many have also been involved in diverse aspects of security, including on the front lines with forces trying to reduce the threat from terrorism.

The events of 9/11 triggered years of counter terrorist efforts by the USA and its global partners. However, Dr Joana Cook, Senior Research Fellow at the International Centre for the Study of Radicalisation, says women were not adequately considered in the counter terrorist strategies developed since the events of 9/11, and this has created a major gap in how we understand and respond to terrorism today.
