Magistrate Rashi Mezher said the suspects were detained earlier this month in different areas in Lebanon. They include seven Syrians, three Lebanese, a Saudi, a Jordanian, and a Palestinian.
Mezher said he has seen no proof that the suspects are members of Al-Qaeda.
Although Al-Qaeda has rarely carried out attacks in Lebanon, it is believed that the group has supporters and sympathizers among extremist factions hiding in Palestinian refugee camps in Lebanon.
