When ISIS swept into the northern Iraqi town of Sinjar in 2014, a few young Yazidi women took up arms against the militants attacking women and girls from their community. “They took eight of my neighbors and I saw they were killing the children,” Asema Dahir told Reuters last month at a checkpoint near a front line north of Mosul. Dressed in military fatigues, the 21-year-old is now part of an all-female unit in the Kurdish peshmerga forces, which have played an important role in pushing back ISIS in northern Iraq.
