"KHARTOUM - Sudan asked the United Nations Security Council on Tuesday to meet and discuss a dispute over a giant dam being built by Ethiopia on the Blue Nile, a government statement said.
Ethiopia is pinning its hopes of economic development and power generation on the Grand Ethiopian Renaissance Dam (GERD), while the two downstream countries - Egypt and Sudan - are concerned about it and seeking a binding agreement on the filling and operation of the dam.
Egypt relies on the Nile River for as much as 90% of its fresh water and sees the dam as an existential threat. Sudan is concerned about the operation of its own Nile dams and water stations."
