BARCELONA, Dec 13 (IPS) - It was a hellish journey aboard a crammed boat amid three-meter waves. It had started on a Libyan beach, and at the gates of winter. On December 11, the last 500 migrants rescued from the waters of the Mediterranean disembarked exhausted but relieved in the south of Italy. They had all been rescued by vessels run by NGOs Doctors Without Borders (MSF) and SOS Humanity.
