I strongly suspect that the vast majority of people in Lampedusa are not actually from Libya or whatever. Libya probably doesn't want random countries showing up and dumping people from random countries off on their beach, and countries don't really have a right to do that.
The normal convention, if you're gonna deport someone, is to deport people to their country of origin. Like, if some guy is from Sudan and he's illegally present in your country, he gets deported to Sudan.
Looking at the crowd, everyone there looks to be from sub-Saharan Africa, not North Africa.
