Not everyone survives this journey. A recent U.N. report has found that 2016 is set to be the deadliest year for refugees crossing the Mediterranean. Far fewer migrants have attempted the crossing this year, perhaps in part due to the huge death tolls — and anti-immigration crackdowns — in 2015. But nevertheless, more of them are dying, with at least 3,740 people reported killed this year: roughly one in every 47. While Mediterranean countries clamp down on border control, no easy solution seems to be in sight.
