The Israeli army launched on Wednesday an air balloon with surveillance cameras from one of its military positions opposite the area of Kroum al-Sharaqi- Mays al-Jabal, in the district of Marjayoun, the National News Agency reported on Wednesday.

NNA added that Israeli troops have also installed a surveillance camera, over the cement separation wall between Lebanon and occupied Palestine, in the area of al-Abbara near Kfarkila.

The camera was pointed at the Lebanese territories, it said.

The Israeli activity comes one day after it announced an operation against what it said were Hizbullah infiltration tunnels.

The operation dubbed "Northern Shield" aims to destroy "attack tunnels" that Israel accused the Iran-backed Hizbullah of digging under the border.
