12-member Israeli force crossed the electronic fence overnight in the outskirts of the southern border town of Mays al-Jabal in the Kroum al-Sharqi area, media reports said Wednesday.
Troops planted spy devices consisted of a camera and a transmission instrument that are both solar powered, the reports added.
The development comes amid high tensions between Israel and Hizbullah that follow an exchange of threats and amid unconfirmed reports of Israeli airstrikes on Hizbullah posts inside Syria.
