About 900 Arab refugees are crammed into a boat which capsizes 60 miles off the Libyan coast in April 2015, killing about 850 people. This is the worst single incident in an increasing influx of refugees from boats leaving the Libyan coast for Italy. About 171,000 refugees from North Africa made this journey in 2014, and increasing numbers are doing it in 2015 to flee the civil wars in Syria and Libya, and hardship conditions in Tunisia, Eritrea and other sub-Saharan countries.
