Egypts president says he will meet with the Ethiopian prime minister in efforts to restart critical talks over Ethiopias soon-to-be-finished Blue Nile dam, which Cairo says threaten its water supply. Abdel-Fattah el-Sisi said in televised remarks Sunday the meeting with Abiy Ahmed will take place in Russia. Sisi didnt disclose the time of the meeting, but he will co-chair a two-day Russia-Africa summit on Oct. 23 in the coastal city of Sochi. The development comes a week after Egypt, Ethiopia, and Sudan failed to resolve their differences in yet another round of meetings. Egypt says filling the Grand Ethiopian Renaissance Dams giant reservoir will severely diminish its portion of waters downstream, and has called for international mediation to help reach a "fair and balanced" agreement.
