In this Sunday, Aug. 10, 2014 photo, a U.S. flag waves while displaced Iraqis from the Yazidi community cross the Syria-Iraq border on Feeshkhabour bridge over Tigris River at Feeshkhabour border point, northern Iraq. Kurdish authorities at the border believe some 45,000 Yazidis passed the river crossing in the past week and thousands more are still stranded in the mountains.
