EGYPT - Egypt’s president said Tuesday his country’s share of the Nile River's waters are “untouchable" in a stark warning apparently to Ethiopia, which is building a giant dam on the Nile's main tributary. The comment from President Abdel Fattah el-Sissi comes amid a deadlock in the years long talks over the dam between the Nile Basin countries, which also includes Sudan. In a news conference, el-Sissi warned of “instability that no one can imagine” in the region if the Grand Ethiopian Renaissance Dam is filled and operated without a legally binding agreement. “No one can take a single drop of water from Egypt, and whoever wants to try it, let him try," he said. “No one imagines that it will be far from our capabilities.”
