Five suicide bombers blew themselves up during military raids on two refugee encampments in Lebanon’s Arsal area near the border with Syria, leaving seven soldiers injured, the army said.

Four of the bombers struck in one camp housing Syrian refugees near the border town of Arsal, wounding three soldiers, said a communique issued by the army command.

Media reports said that a child was also killed when one of the suicide bombers blew himself up.

The army command said that one militant blew himself up in a second camp near Arsal, while another militant threw a grenade at troops wounding four of them.

The raids, which are aimed at “arresting terrorists and seizing weapons,” are still ongoing, the communique added.

The state-run National News Agency said that during the raids the army arrested several people suspected of contacting militants in Arsal’s outskirts.

A military explosives expert also defused several bombs planted in one of the encampments, NNA added.

Terrorists have staged regular incursions into Arsal from the barren hills just outside. They overran the town briefly in 2014 before withdrawing to the hills after clashes with the army.

The camps around Arsal have also long been a haven for the militants coming from Syria.

The Lebanese army has in recent months stepped up raids in the makeshift camps built on the edge of the town.
