The European Union (EU) has said it will not create a "Guantanamo Bay for migrants" as it pushes ahead with plans for centres in North Africa.
Dimitris Avramopoulos, the EU's commissioner for migrants, said the group was talking to various United Nations agencies about the proposals.
He said they were now looking at ways to "further engage northern African countries in discussions on possibilities for regional disembarkation schemes".
However, he stressed these centres would not end up like the notorious detention centre set up by the US in Cuba, which has been accused of numerous human rights' abuses.
He told reporters:
EU leaders will discuss the plans at a June 28-29 summit.
