IDF security personnel have been performing tests in the past few weeks along the border with Lebanon. Channel 2 news reported that the IDF suspects Hezbollah terrorists have been digging tunnels in order to cross into Israel for attack purposes. The tests come after last month's discovery of a terrorist tunnel dug by Hamas near the Gaza border, in order to carry out a bomb attack.
