Tunnel

In the end, the Hezbollah Maginot Line fell in southern Lebanon. It has taken many years to uproot the infrastructure that was built over the last decades.

The IDF has encountered several individual Hezbollah operatives in the area over the past several months, which the Alma center said supports the possibility of a continued Hezbollah presence.

Drone footage released by the IDF Spokesperson's Unit shows the tunnels running underground at length, packed with sandbags.

Kushner said Hamas could surrender weapons and tunnels within 60 to 90 days, calling demilitarization a potential major security gain for Israel.

Observers from the Border Police patrol unit first noticed the group digging a tunnel near the fence and alerted officers in the field, who then went to the scene. 

A video released by the IDF shows footage from a body camera on a military dog of the IDF's K9 unit, Oketz, exploring the cave and finding dozens of munitions.

The tunnel network was intended not just for surveillance, but also to facilitate attacks on Israeli troops and communities near the Lebanon border.

Earlier on Monday, the military said a Hamas tunnel network in northern Gaza was discovered and destroyed by the IDF's Northern Gaza Brigade and Yahalom Unit.

Survival chances for the trapped workers were slim, state disaster management official Rajiv Roka said, as rescuers had to battle the fumes, making their task difficult.

In this war, the soldiers of S-2 are no longer just an engineering unit but have become a living laboratory of underground warfare.
