A lot of people try to get into the EU by going to one of three locations which are in or close to Africa, Lampedusa, Ceuta and Melilla. Quite horrific images are the result of this.
The part I don't understand is why these locations are so crucial. Technically they are part of the EU, but they are also remote. People would still need to cross the Mediterranean Sea to get to locations with more job opportunities.
I assume since the crossing is done without papers, just taking the ferry to the mainland is not an option. Still getting to these areas must be sensible given the constant number of people trying to get there.
