A controversial deal has been signed to share the waters of the world's longest river.
But Egypt and Sudan are not happy at four African countries signing a new deal on the Nile.
Rwanda, Ethiopia, Uganda and Tanzania signed the new framework on Friday while Kenya issued a support statement.
Ten nations share the resources of the river.
Colonial-era agreements gave the biggest share of water to the two downstream countries, Egypt and Sudan.
But as Al Jazeera's Mohamed Vall explains, upstream nations are now pushing for a greater share.
