Smugglers made more than $5 billion from migrants in 2015, according to a joint Interpol-Europol report, released on Tuesday. Migration to the EU is "predominantly facilitated by members of a criminal network," the report said, and migrants paid on average between $3,200 and $6,500. Europol and Interpol expect more migrants will attempt to enter Europe in 2016 than in 2015, and the proportion who use smugglers is expected to rise above 90 percent.
