The source said that General Security's Information Bureau detained Omar Ghannoum, who is a prominent ISIL official, in the Bab al-Ramel neighborhood.

His arrest came as a result of monitoring a group involved in recruiting Lebanese to join ISIL and carrying out and facilitating terror acts, according to the source.

Residents of Tripoli have been increasingly concerned about the number of youths who have left to join ISIL and the Nusra Front.

Hundreds of people from the north are believed to have joined extremist groups in Syria and Iraq.

Occasionally information is leaked stating that one has been killed in north Syria or Iraq. Their families are informed by a call from ISIL, telling them that their child has been killed, and buried.

As more young people become affiliated with extremist groups in Tripoli, suspicion has grown among the city’s residents.

Whenever someone announces that they are heading to Turkey for vacation, they immediately become the object of mistrust.
