According to reports, the militants have also been found using gangs trafficking migrants over the Mediterranean to get IS members to the West. These militants have been termed as ‘prize operatives' because they can travel undetected around Europe and to Britain.
The report further says, ISIS is also giving money to people smugglers to promote terrorism. They make £60,000 per boat of refugees who attempt the journey, it is claimed.
They may also force families in refugee camps on the borders of Lebanon and Jordan to flee to Libya. The migrants are forced to join IS or take a seven-day Sharia law course before travelling to Europe, said the report.
Abdul Basit Haroun, adviser to the Libyan government's intelligence service, said he had spoken to boat owners operating in IS-controlled areas, who said the group takes 50 per cent of their income.
'They use the boats for their people who they want to send to Europe as the European police don't know who is from IS and who is a normal refugee or not.
‘The boat owners have a list of who to take but some people come suddenly out of the list and they're told, "Take them with you" ... they come alone and in the boat they are not scared at all. They are for IS, 100 per cent.'
The investigation uncovered claims two Egyptian brothers travelled to Europe in March from Sirte, Libya, after traffickers told them IS offered safer, cheaper journeys.
