Several of the people picked up by the Aquarius over the last few months could not have claimed to be refugees, since their countries are not at war, and there has been no particular danger to them there.
Examples are Senegal, Nigeria, Chad, Ivory Coast and Mali. These are undoubtedly economic migrants.

But what can one do? Chuck them back in the sea? Shoot them?
Thank goodness the Spanish region of Basque agreed to accept them. They can be processed (with kindness and humanity I hope) and due arrangements made for their futures.
