Yazidi People Hold Religious Ritual At Holy Shrine

LALISH, IRAQ - NOVEMBER 06: Women sweep in the daily cleaning of the temple of Lalis the most holy site of the Yazidi religion on November 6, 2015 in Lalish, Nineveh Province, Lalish, Iraq. Many Yazidi visitors to the main Lalish temple were displaced from Sinjar Mountain, which was overrun by ISIS in 2014, when ISIS killed thousands of the men and enslaved many Yazidi women. The Yazidis, one of the most impoverished groups in Iraq, had been widely descriminated against, even before being more severely targeted by the Islamic State. The Yazidi religion, which has some similar religious symbols to Hinduism and maintains a caste system, predates Judaisim and Christianity as one of the world's most ancient faiths.
