万余伊拉克人逃离摩苏尔

The International Organization for Migration says more than 10,000 Iraqis have been displaced since the start of an operation to retake the northern city of Mosul from Islamic State militants.

The offensive, which involves Iraqi government troops, Kurdish fighters, Sunni tribesman and Shi'ite militias, began last week and has so far involved capturing town and villages surrounding Iraq's second largest city.

The United Nations warned last week that as many as 200,000 people could be displaced in the initial weeks of the fight for Mosul, and that humanitarian groups would initially be able to handle about 70,000 people in need of aid.

Iraq's displacement and migration ministry said Wednesday the number of displaced was increasing, and that on Tuesday there was a "big wave" of 3,300 people in what was considered the largest number of people fleeing since the Mosul operation began.

The United Nations said Tuesday it had preliminary reports of extrajudicial killings and summary executions by Islamic State fighters around Mosul, including the militants using civilians as human shields.
