Nile dam dispute spills onto social media

As Egypt, Ethiopia and Sudan struggle to resolve a long-running dispute over Addis Ababa's mega-dam project on the Nile, some of their citizens are sparring online over their rights to the mighty waterway. For nearly a decade, multiple rounds of talks between Cairo, Addis Ababa and Khartoum have failed to produce a deal over the filling and operation of the Grand Ethiopian Renaissance Dam (GERD). Anxiety has mounted in downstream Sudan and Egypt, which fear for their vital water supplies after upstream Ethiopia declared plans to start filling Africa's largest dam reservoir in July.
