"Kurds of the ethnic minority of Yazidis hold up a banner reading ""Stop genocide against Yazidis in Iraq"" as they march through the streets of Bielefeld August 9, 2014.  Some 10,000 ethnic Kurds of the Yazidis sect, who practice an ancient faith related to Zoroastrianism, protested in the western German city on Saturday against Islamic State (IS) militants, who are surging across northern Iraq near the Kurdistan borders in their drive to eradicate unbelievers such as Christians and Yazidis.
