The Lebanese army on Monday raided Syrian refugee encampments outside the eastern border town of al-Qaa, including in the Masharii al-Qaa and Nuaimat areas, state-run National News Agency reported.
Troops from the Lebanese army's Airborne Regiment arrested 35 Syrians in the raids and seized a number of motorcycles, LBCI television said.
NNA meanwhile said that the army "seized all motorbikes at the encampment and arrested several people who were not carrying identification papers."
Later in the day, the agency said 25 of those arrested were freed as ten were kept in custody.
The raids are part of a major crackdown that followed unprecedented suicide bombings in the predominantly Christian border town of al-Qaa.
Eight suicide bombers attacks the town in two waves last Monday, killing five people and wounding 28 others.
