The Lebanese Armed Forces (LAF) has detained four Al-Nusra Front radicals and about 470 suspected Islamist militants in Ersal, Tripoli, Akkar, and Koura, local media reports quoted Lebanese security sources as saying on Thursday.
Last month, Ersal was the scene of the deadliest spillover of fighting in the three-year crisis in Syria.
During those clashes that killed dozens, Daesh and al-Nusra Front militants captured a group of Lebanese soldiers and have since killed at least three of them.
