KHARTOUM (Reuters) - Sudan has rejected an Ethiopian proposal to manage the filling for a second time of a giant dam that it is building on the Blue Nile, a senior official said on Sunday, deepening a regional dispute over the project.

Ethiopia has pinned hopes of development and power generation on the Grand Ethiopian Renaissance Dam (GERD), while downstream Sudan is concerned about regulating flows to its own dams and Egypt fears an impact on its water supply.
