"We are being slaughtered. Our entire religion is being wiped off the face of the earth," a Yazidi MP, Vian Dakhil, was quoted as saying in parliament.
Islamic State swept across most Sunni parts of Iraq at the beginning of June, seizing the second-biggest city, Mosul, and the birthplace of Saddam Hussein, Tikrit. Its fighters are still attacking Shia-majority areas in the centre and south of Iraq, including within a few miles of Baghdad, but have held off from a full-frontal attack. They seemed also to have been held up by Kurdish forces in the north and east, which guard the Kurdistan autonomous region. However, Kurdish forces too were forced to retreat by a sudden advance across a 130 kilometre front at the weekend, and abandoned Sinjar.
The jihadists' advance has sent Christians, Shia, and other minority groups flooding into Kurdistan for protection.
The Yazidis mostly fled south when Sinjar was attacked, but the mountains where they are hiding are cut off by Islamic State. Some photos have emerged of lines of cars, and groups of people huddled at the entrance of caves.
The army has managed to drop some supplies by helicopter, but not enough.
"The civilians trapped in the mountain area are not only at risk of being killed or abducted; they are also suffering from a lack of water, food and medical care," Ms Rovera said. Amnesty claimed the Kurdish government had begun blocking access to refugees. The Peshmerga announced their troops were in the area, but have so far been unable to reach the refugees.
"The plight of displaced people caught up in the fighting in Iraq is increasingly desperate," Ms Rovera said.
