Israel's strategic sabotage of Hezbollah's communication devices exposed the terror group's vulnerabilities.
Norwegian security police investigate potential links between a Norwegian-owned company and pagers used in recent Hezbollah attacks in Lebanon.
Israel must continue applying psychological pressure on Hezbollah and Lebanon to exploit the group's vulnerabilities and eventually break its resolve to fight.
The Jerusalem Post has exclusively learned that whoever caused the sabotage did not pick the timing because of a sudden discovery by Hezbollah.
The way the explosive material was integrated into the battery pack made it extremely difficult to detect, the source said.
The Shin Bet agency did not name the official. It said in a statement that it had seized an explosive device attached to a remote detonation system that Hezbollah had planned to operate remotely.
Security forces also killed a terrorist who threw explosive devices and dismantled a vehicle rigged with explosives.
Security forces are investigating the possibility of a third vehicle.
One of the terrorists killed was involved in the shooting attack that led to the murder of an Israeli civilian, Amnon Muchtar, in June.
The IDF, Shin Bet, and Border Police have confiscated about 150 sacks of materials intended for making explosives to target soldiers.
