CNN Exclusive Explores ISIS Fighters Mixing In with Refugees

CNN showed how Islamic State terrorist fighters are blending in with legitimate refugees and traveling to Europe in an exclusive report Thursday.

CNN Senior International Correspondent Nick Paton Walsh traveled with the Libyan Immigration Police near Tripoli and went into a warehouse that was being used by refugees until police raided it.

"But there is a new threat here, smugglers and police telling us that ISIS have hidden fighters among other groups of migrants bound for Europe. This trade in human souls is awful enough until you think that perhaps ISIS are using this passage of human life into Europe to try and infiltrate the continent with sleeper cells," Walsh said. "Police tell us off-camera they've caught different, other migrants with ISIS links and a top Libyan intelligence officials warns us, the threat is real."

"ISIS can be among the illegal immigrants on the boats," said Ismail al-Shukri, a police commander. "They travel with their families, without weapons as normal illegal immigrants. They will wear American dress and have English language papers so they cause no suspicion."

Walsh then spoke with a smuggler who refused to have his identity known, but said that he and other smugglers know that they frequently will ferry ISIS members between Libya and Europe.

"Do you and other smugglers feel comfortable moving people who may be ISIS towards Europe?" Walsh asked the smuggler.

"Smugglers are only interested in smuggling," he said. "Only money matters."

Walsh also spoke with those who were trying to flee from terrorism, including one from Nigeria who said he had lost two family members in a bombing.
