All options are on the table when it comes to GERD, but let’s cooperate, shall we? That was President Abdel Fattah El Sisi’s message to Ethiopia in a public address earlier today (watch, runtime 3:19) after Egypt, Sudan, and Ethiopia walked away from four days of talks on Monday without reaching an agreement on the mechanism for the filing and operation of the Ethiopian dam. El Sisi reiterated Egypt’s rightful claim to its share of the Nile’s waters under international law, and referred to the natural elevation of the Nile’s path, saying, “What was made by God will not be changed by man.”

Egypt is coordinating with Sudan on next steps, the president said, and cautioned Ethiopia once again not to “let things get to the stage where you affect even a drop of Egypt’s water,” repeating his warning to Ethiopia last week that this would cause instability in the region. Ethiopia has repeatedly rejected Sudan and Egypt’s proposal to bring in international mediators, insisting instead to keep going with African Union-led talks. Addis Ababa meanwhile also hasn’t budged on its plans to press ahead with the second filling of its dam come the rainy season this June.

Foreign Minister Sameh Shoukry made a brief pitstop in Khartoum early this morning following the conclusion of the talks, before heading to Beirut immediately afterwards, Youm7 reports. It was unclear which Sudanese officials Shoukry met with during his visit.
