It is widely known that Hezbollah possesses an extensive tunnel network across Lebanon. However, an Israeli Alma Research Center report suggests that over the past two decades, the group has developed a large-scale Military Tunnel project—one of its most significant investments in terms of cost and infrastructure.
According to the study, the network is not limited to southern Lebanon. It also extends to Beirut’s southern suburbs, the Bekaa Valley, and the Lebanese-Syrian border. It reportedly includes strategic tunnels containing command-and-control rooms and weapons depots, tunnels connecting operational areas, tunnels near the border, as well as offensive tunnels and others designed for demolition operations.
The center estimates the project’s cost at between $1 billion and $3 billion, noting that some strategic sections may extend for dozens of kilometers. It cites, for example, an estimated tunnel route approximately 45 kilometers long in the Iqlim al-Tuffah region.
The project was reportedly developed with Iranian and North Korean support and with the involvement of engineering entities linked to Hezbollah. Its purpose was to secure the movement of fighters and commanders and protect the group’s military capabilities underground during any confrontation.
These claims, however, originate from an Israeli research center and rely heavily on intelligence estimates and security analysis. Not all the details or figures have been independently verified, leaving the network’s true size, cost, and geographical reach open to debate.
