The Lebanese army and militants clashed on the outskirts of the northeastern village of Ras Baalbek overnight as troops targeted fighters in the areas surrounding the town of Arsal, the state-run National News Agency reported on Tuesday.
NNA reported shooting incidents and skirmishes between armed groups and the military's bases in the area of Tallet al-Hamra that lies in Ras Baalbek's outskirts.
Last month, eight soldiers were killed in the same area in a battle between troops and Syria-based fighters from the Islamic State group.
The cross-border attack was the most serious since IS and al-Nusra Front militants seized Lebanese soldiers and policemen in a raid in Arsal in August 2014.
