Several hundred Yazidi captives have been slaughtered by Islamic State (IS) militants near Mosul in Iraq.
According to the Yazidi Progress Party, the captive Yazidis were murdered on 1 May in the Tal Afar district. According to Shafaq News the party condemned the "heinous criminal acts" committed by the terror group.
Iraqi Vice-President Osama al-Nujaifi described the mass killing as "horrific and barbaric".It is not clear how they were killed, or why this has happened now.
40,000 Yazidis were kidnapped at gunpoint when the terrorists attacked their villages last summer. Some Yazidi women were held and sold in markets as sex slaves.
The religious minority group whose ancient religion has elements of Zoroastrianism, Christianity and Islam, have been persecuted by IS, who regard them as infidels and devil-worshippers.
Thousands fled to the Kurdish-controlled region of northern Iraq after IS captured the Yazidi-populated Sinjar district in Nineveh province.
In January, IS released some 200 mainly elderly Yazidis into the hands of Kurdish officials near the city of Kirkuk. Many of them, women, children and the elderly, held in Mosul, had disabilities or were wounded and were said to be in poor health, bearing signs of abuse and neglect.
The freed Yazidis were taken away by ambulances and buses to receive treatment and care. No explanation was given for the release of the prisoners, which took place in Himera just south west of Kirkuk, 180 miles north of Baghdad.
In March, the United Nations Human Rights Office published a report describing the savage killings, torture, rape and sexual slavery of Yazidis by the Islamic extremists.
The jihadists consistently separated out men and boys over the age of 14 to be executed, according to investigators.
Younger boys were forced to become child soldiers and women and girls were abducted as the 'spoils of war'. The UN condemned the act of violence, rape and abuse of children as war crimes.
In light of the mass killing, the Yazidi Progress Party statement has now called on the government in Iraq and international organisations to intervene to facilitate the release of the remaining captives.
