Portugal's President Marcelo Rebelo de Sousa has said that his country must take full responsibility for colonial-era abuses and that there are circumstances in which reparations should be paid.

President de Sousa has several times expressed regret for Portugal's role in enslaving and colonizing Africans.

Now, he's said that in some cases it should "pay the costs" for wrongs done - such as when massacres took place under colonial rule, or where significant items were looted and never returned.
