A small cruise boat passes Nile City Towers, which is owned by Naguib Sawiris the owner of Orascom Telecom, overlooking the river Nile in Cairo June 7, 2013. Most of Egypt's population live clustered around the Nile valley and delta, and the river is both a vital resource for the country's citizens, and a potent national symbol. In a recent dispute with Ethiopia over the construction of a dam upstream, Egypt's foreign minister Mohamed Kamel Amr underlined the country's reliance on the river's waters: "No Nile - no Egypt," he said.
