An urgent evacuation plan has been devised for migrants facing abuse in Libyan detention camps.

It was drawn up at an African Union-European Union summit in Ivory Coast.

Libya's UN-backed administration joined the agreement, but has only limited control over the territory, raising questions about how it will work in practice.

The migrants will be sent mainly back to their home countries.

The move follows the publication of video footage that appeared to show migrants from sub-Saharan Africa being sold in Libya as slaves.

French President Emmanuel Macron called the slave auctions a "crime against humanity"
