ADDIS ABABA (Reuters) - Ethiopia has banned all flights over its giant new hydropower dam on the Blue Nile for security reasons, the head of its civil aviation authority said on Monday, as the president pledged the dam would begin generating power in the next 12 months.

The move could worsen Ethiopia's dispute with Egypt and Sudan over its $4 billion Grand Ethiopian Renaissance Dam, which Cairo has said could threaten its main supply of water.
