The Lebanese army arrested on Sunday a number of armed Syrians in the Bekaa region of Arsal, reported Voice of Lebanon radio (93.3).
It said that a shootout broke out between the army and the four Syrians when they opened fire at an army patrol in the Wadi Hmayyed area.
Al-Jadeed television said that a fifth Syrian managed to escape the scene.
Investigations are underway with the assailants.
On Thursday, a Syrian was killed and two others were wounded by the army in Arsal.
The army was forced to open fire at the Syrians after they fled from an army checkpoint in Wadi Hmayyed.
Arsal lies 12 kilometers from the border with Syria and has been used as a conduit for weapons and rebels to enter Syria, while also serving as a refuge for people fleeing the conflict.
