More than 300 migrants crossing the Mediterranean Sea in a clandestine convoy from Libya to Italy were reported drowned this week when their boats overturned off Lampedusa, just days after 29 other seaborne migrants were discovered dead from hypothermia close to the Italian coast. The tragedies follow the narrow rescues in December and January of more than 1,200 Syrian migrants from two rusting ‘ghost’ freighters left abandoned by people smugglers to their fate. Earlier this month, Mediapart’s Carine Fouteau joined the Týr, an Icelandic coastguard ship patrolling the central Mediterranean as part of an operation mounted by the EU border-policing agency Frontex. She heard the harrowing experiences of the Týr’s proud crew who have already rescued 2,000 migrants in difficulty, and questioned Frontex officials about what is an increasingly confused mission. But she begins this report with the dramatic events she witnessed aboard the Týr, when a drifting, apparently crewless rusting freighter suspected of carrying hundreds of migrants in its hold was left to its fate overnight in strong seas - because no-one had sent out an SOS.
The discovery last week of two abandoned cargo ships crammed with clandestine migrants in the Mediterranean Sea has underlined a cynical change of tactics by people traffickers. Though buying the massive vessels costs money, the traffickers still stand to make millions from preying on the desire of refugees to flee war-torn Syria or the Horn of Africa for a better life in Europe. Mediapart has been reporting regularly on the plight of migrants and refugees crossing the Mediterranean and has highlighted the new tactics being used by traffickers. Here Carine Fouteau looks at the background to people smuggling and describes just how traffickers exploit the needy – including wealthier middle class Syrians desperate to escape the ongoing war in their country.
