The army command said Thursday a group of gunmen aboard a pickup truck attacked an army checkpoint Wednesday overnight in the area of Wadi Hmeid in the outskirts of Arsal.
Two of the assailants, a Lebanese and a Syrian, were killed while the rest were able to escape, a statement said.
The army confiscated the pickup truck, and seized a quantity of weapons and ammunition.
Another armed group attacked the same checkpoint later in the night, however no soldiers were wounded in the attack.
