BAGHDAD (Reuters) - Islamic State militants have threatened to kill more than 300 families from Iraq's Yazidi ethnic minority unless they convert to Islam, witnesses and a Yazidi lawmaker told Reuters on Saturday.
The families in the villages of Koja, Hatimiya and Qaboshi are surrounded by the Sunni militants who are mounting an offensive through northern Iraq which has sent tens of thousands of Yazidis and Christians fleeing for their lives, prompting international outrage.
