Lebanon on Monday charged 28 people, including a Saudi citizen and two French nationals, with belonging to the jihadi Islamic State of Iraq and Syria (ISIS), a judicial source told AFP.
The men, only seven of whom are in custody, also face charges of seeking to carry out suicide attacks, said the source.
A Saudi citizen and one of the French nationals were arrested in June, on the basis of US intelligence, as Lebanon was rocked by three suicide bombings in less than a week.
The second French national facing charges is still at large.
The group also includes five Lebanese citizens, the source said, with the nationalities of the others accused not specified.
The men are accused of belonging to the ISIS, which says it now wants to be called the Islamic State after declaring the formation of a “caliphate” over territories in captured in northern Syria and Iraq
They are also accused of preparing suicide bombings, and purchasing explosives and weapons.
The Saudi citizen was arrested on June 25 in a Beirut hotel.
As police raided the hotel, the man’s accomplice blew himself up, killing himself and wounding 11 people.
The French citizen was arrested the week before, also in a Beirut hotel, and is of Comoran origin.
