Egypt declared an Ethiopian diplomat *persona non grata* on Thursday, ordering them to leave the country within 48 hours. This retaliatory measure follows Ethiopia’s earlier expulsion of an Egyptian diplomatic staff member. According to local press reports, an Egyptian source described the decision made in Addis Ababa as “regrettable and unjustified.” The move signals escalating tensions between Egypt and Ethiopia, particularly concerning the Grand Ethiopian Renaissance Dam on the Nile River. Further details regarding the specific accusations against Ethiopian authorities were not immediately available. The incident highlights a continuing dispute over the dam’s construction and its potential impact on Egypt’s water supply. This diplomatic fallout underscores the sensitivity of the Nile River issue for both nations.
