US military advisors were headed for Iraq’s Mount Sinjar to study means of evacuating thousands of civilians trapped by jihadists with little food or water, a Kurdish spokesman said Wednesday. The United States has carried out air strikes against jihadists of the Islamic State (IS) group in the area of Mount Sinjar in northern Iraq, where the UN refugee agency has said tens of thousands of civilians, many of them members of the Yazidi minority, remain stranded.
