French report cites military sources who served in Lebanon, who say Hezbollah used quiet on the border to construct hundreds of kilometers of complex underground systems for infiltration and defensive purposes

An investigative report in the French newspaper Libération claimed Sunday that Hezbollah has been digging hundreds of kilometers of underground tunnels in Lebanon for over 30 years, some of them reaching depths of 40 meters to 80 meters, using North Korean technology. The report noted that the tunnels are more complex and dangerous than those in Gaza, and the explosion of some of the tunnels could cause earthquakes or landslides.
