GENEVA - People smugglers made over $5 billion from the wave of migration into southern Europe last year, a report by international crime-fighting agencies Interpol and Europol said on Tuesday.

Nine out of ten migrants and refugees entering the European Union in 2015 relied on "facilitation services", mainly loose networks of criminals along the routes, and the proportion was likely to be even higher in 2016, the report said.

About 1 million migrants entered the EU in 2015, and most paid 3,000-6,000 euros ($3,400-$6,800), so the average turnover was likely between $5 billion and $6 billion, the report said.
