Information is leaked about an alleged secret agreement that would allow Egypt to build an air base in Sudan to attack the Grand Ethiopian Renaissance Dam (GERD). Egypt is concerned that the dam, under construction in Ethiopia just upstream of Sudan on the Blue Nile, would reduce flows into its territory. The news reports, strongly denied by Egypt, claim that Sudan would allow Egypt to launch attacks if diplomatic efforts fail to resolve water sharing between Egypt and Ethiopia. The allegations are based on an internal 2010 email made available by Wikileaks.
