Islamic State, a militant group that witnesses and officials say has executed hundreds of members of Iraq's Yazidis, has released a video that seeks to show it enlightened hundreds of members of the religious minority by converting them to Islam.
The production was issued not long after the group on Tuesday released a video showing one of its black-clad fighters beheading American journalist James Foley, sparking international outrage.
The Yazidis, followers of an ancient religion derived from Zoroastrianism who are part of the country's Kurdish minority, have paid the highest price for Islamic State's dramatic advance through northern Iraq.
