A top Sudanese general on Sunday said his country would mediate a deal on an escalating dispute between Ethiopia and Egypt over Ethiopia’s controversial dam on the Nile River. The deputy head of Sudan’s Sovereign Council, Mohamed Hamdan Dagalo, said his country would work to bridge the gap and “reach an agreement” in the years-long dispute. Tensions are rising in east Africa because of the impasse between Ethiopia and Egypt over the $4.6 billion Grand Ethiopian Renaissance Dam. It’s around 71% complete and promises to provide much-needed electricity to Ethiopia’s 100 million people. Egypt fears the project — set to be Africa’s largest hydraulic dam — could reduce its share of the Nile, the main source of freshwater for Egypt’s population, also more than 100 million people.
