Syrian refugees cross into Iraq at the Peshkhabour border point in Dahuk, 260 miles (430 kilometers) northwest of Baghdad, Iraq, Tuesday, Aug. 20, 2013. Around 30,000 Syrians, the vast majority of them Kurds, have fled the region over a five-day stretch and crossed the border to the self-ruled Kurdish region of northern Iraq. Another 4,000 made the trek across the frontier Tuesday, said Youssef Mahmoud, a spokesman for the UNHCR in Iraqi Kurdistan. (AP Photo/Hadi Mizban), APTOPIX
