NNA said in the army's operation took place in Khirbet Daoud..
The threat of terrorists, deployed on the porous Lebanese-Syrian border, rose a year ago when al-Nusra Front and so-called “Islamic State” (ISIS/ISIL) group fighters overran Arsal and engaged in heavy battles with the army.
The gunmen took with them hostages from the military and police and later executed four of them.
Since then, the terrorists are carrying out several infiltration attempts but troops, which are heavily deployed in the area, are confronting them.
