Ethiopia's leader has vowed that no one will stop a $4.2 billion energy project that is diverting the flow of the Nile River.

His comments come a day after Egypt's president warned that all options were being considered to halt the dam.

Ethiopia started diverting the flow of the Nile River in late May to make way for its hydroelectric plant, which will be Africa's largest. Egypt fears that the project will mean a diminished share of the Nile River.

In an interview aired Tuesday, Ethiopian Prime Minister Hailemariam Desalegn said that he did not think Egypt would start a war over the vital river.

Ethiopia says that an experts' panel already has concluded that the dam will not significantly affect water flow to both Egypt and Sudan.
