When the Assad regime was forced from the northeastern city of Raqqa in the summer of 2013, Souad Nofal was elated. A schoolteacher in the town, she belonged to a revolutionary group that used non-violent tactics to instigate civil unrest. ‘We rushed into the street, crying and singing,’ she remembers. ‘I wanted to live as they do in the countries we see on the TV – for a person to say whatever they want and not be afraid.’

The elation was short lived. The Islamist group that had just started to call itself ISIS quickly became a major presence in the city. Many of Raqqa’s revolutionaries left, and those that remained were intimidated into silence. But as Nofal saw the revolution’s promise betrayed, she decided to confront the Islamists.
