A Lebanese Army Intelligence Unit busted on Thursday two "security cells" belonging to the Islamic State terrorists group (IS), local media reported.
Citing LBCI television, Xinhua reported said that nine were detained and most of them are Lebanese.
The arrested suspects are still being interrogated by the Intelligence Directorate, the TV station added.
It was not immediately clear where and how the nine suspects were arrested.
The General Directorate of General Security had recently announced the dismantling of an IS cell that had been planning attacks in the country during the holy month of Ramadan.
