An Iraqi man walks past a canoe siting on dry, cracked earth in the Chibayish marshes near the southern Iraqi city of Nasiriyah on June 25, 2015. Marsh areas in southern Iraq have been affected since the Islamic State group started closing the gates of a dam on the Euphrates River in the central city of Ramadi, which is under the jihadist group's control.
