Ethiopia's Prime Minister Abiy Ahmed on Thursday said a multi-billion-dollar mega-dam on the Blue Nile that has long worried neighbouring countries is complete and will be officially inaugurated in September.
The Grand Ethiopian Renaissance Dam (GERD), launched in 2011 with a $4-billion budget, is considered Africa's largest hydroelectric project stretching 1.8 kilometres (just over one mile) wide and 145 metres (475 feet) high.
