In this Wednesday July 9, 2014 photo, Iraqi refugees who fled from Mosul and other towns sit on the floor at a temporary camp outside Irbil, northern Iraq, nearly a month after Islamic militants took over the country's second largest city. The lightning sweep by the insurgents over much of northern and western Iraq the past month has dramatically hiked tensions between the country's Shiite majority and Sunni minority. At the same time, splits have grown between the Shiite-led government in Baghdad and the Kurdish autonomy region in the north. (AP Photo)
