Israeli Defense Minister Yoav Gallant did say on Wednesday, however, that his country's war with Iran's so-called proxy groups in the region had entered a "new phase," announcing a shift to the north of Israel after 11 months of intense conflict with Hamas in the Gaza Strip.

Hezbollah and Israel have traded blows in recent days, as the conflict has escalated with few off-ramps in sight to avoid total war.

The unprecedented attack, followed by explosions of walkie-talkies, comes after Israeli officials warned about escalating tensions on the Lebanese border.

It took years, three different shell companies, and an explosive called pentaerythritol tetranitrate, according to reports.
