"My gut feeling is they [ISIL] are facilitating such an operation. To go to Europe and other places," Lebanese Education Minister Elias Bou Saab said, as quoted by the Daily Mirror tabloid late on Monday.
Saab estimated that at least two percent of the 1.1 million Syrian refugees hosted by Lebanon are ISIL militants secretly plotting to enter Europe in the confusion brought about by the migrant crisis.
He claimed that Lebanese soldiers kidnapped last summer were taken by "people who…came out of the camps."
Cameron also announced a three-year $15-million education support package for refugees in Lebanon.
Last week, Hungarian secret service claimed to have detected two Arab terrorists who managed to get to Western Europe under the guise of refugees as tens of thousands of migrants flee their crisis-torn homelands.
