Iraq conflict: Christians and Yazidis flee amid Islamic State warning
Tens of thousands of Iraqi Christians and Yazidis have fled their homes following a warning by Islamic militants to renounce their faiths or face death.
A quarter of the country's Christians are reported to have fled after the capture of the minority group's biggest town, Qaraqosh.
About 50,000 Yazidis were thought to have been trapped in the mountains after fleeing the town of Sinjar.
