Egypt has said the World Bank should be brought in to resolve tensions with Ethiopia over a massive dam on the Nile River that Egypt says threatens its water security.

Cairo's foreign minister Sameh Shoukry was speaking in Addis Ababa after a 10-month impasse over the dam's technical negotiations.

Tuesday's talks also involve Sudan.

Mr Shoukry calls the World Bank "neutral and decisive" and says "science should be the determining factor" in resolving the issue.

Ethiopia says the Grand Renaissance Dam's construction will not reduce Egypt's water share.

Foreign minister Workneh Gebeyehu says Ethiopia will consider Egypt's proposal and that "this dam is not going to cause any significant harm".

The dam, now 63% complete, will be the biggest hydro-electric plant in Africa.

Ethiopia's leader is expected to visit Egypt next month.
