The Israel Defense Forces on Sunday revealed a major Hezbollah tunnel system near Beaufort Castle in southern Lebanon, which it said was constructed with direct Iranian assistance.

According to the military, the main reason for its raid on the Beaufort Castle area was to capture and demolish the underground site, as well as to prevent the terror group from carrying out rocket attacks on Israel from the area.

“The IDF launched operations in the Beaufort area to achieve operational control over the area, which constitutes a threat to Israeli civilians, and to enable the destruction of the tunnel network,” the military said.

The IDF said the tunnel was “built in a civilian area, in a location that enables operational control over the Galilee panhandle region, only six kilometers (3.7 miles) from Metula, and served as Hezbollah’s center in the area.”

Troops are now working to destroy the “major Hezbollah underground infrastructure site in the Beaufort Ridge area,” IDF Spokesman Brig. Gen. Effie Defrin said in a video statement.

“This is an underground network consisting of several levels excavated deep into the rocky ground. The entire network was built with full funding and planning by the Iranian terror regime over more than a decade,” he said.
