ADDIS ABABA, Ethiopia—Ethiopians in the capital are celebrating progress in the construction of the country’s dam on the Nile River, which has caused regional controversy over its filling.
In joyful demonstrations urged by posts on social media and apparently endorsed by the government, tens of thousands of residents flooded the streets of the capital Addis Ababa on Aug. 2, waving Ethiopia’s flag and holding up posters. People in cars honked their horns, others whistled, played loud music, and danced in public spaces to mark the occasion.
