Lebanese citizen Ismail H., 37, was on Tuesday found dead from a gunshot wound to the head in the Wadi Hmeid region east of the Bekaa border town of Arsal, State-run National News agency reported.
“The corpse was transferred to the al-Rahma field hospital in the town,” the agency said.
“A forensic doctor is expected to examine the body to unveil the circumstances of the incident,” NNA added.
Militants from the Islamic State and the rival jihadist group Fateh al-Sham Front are entrenched in mountainous areas along the undemarcated Lebanese-Syrian border and the army regularly shells their posts while Hizbullah and the Syrian forces have engaged in clashes with them on the Syrian side of the border.
The two groups overran the eastern border town of Arsal in 2014 before being ousted by the army after days of deadly battles.
The retreating militants abducted more than 30 Lebanese soldiers and policemen of whom four have been executed and nine remain in IS’ captivity.
