Core Event
In the early hours of July 30, Israeli forces detonated roughly 700 tons of explosives near Beaufort Castle (Qalaat Al Shaqif) in Lebanon’s Nabatieh governorate. The blast generated seismic waves recorded as a magnitude 3.8 earthquake. Israel’s prime minister Benjamin Netanyahu and defence minister Israel Katz said the operation destroyed “terror tunnels” that Hezbollah had built beneath the ridge and that the tunnels formed part of a command centre for the group’s Badr Unit.
Background & Context
Beaufort Castle, a 12th-century Crusader fortress, was added to UNESCO’s World Heritage List and placed on the World Heritage in Danger List on July 25. The site had been occupied by Israeli forces since May and previously served as an Israeli military base from 1982 to 2000. Israeli officials describe a multi-level underground network built over two decades with Iranian assistance and used to launch drones and missiles against Israeli targets.
The demolition followed a Hezbollah-launched explosive drone that struck an IDF engineering vehicle on the Ali Taher Ridge, an incident Israel labeled a cease-fire violation.
Data & Statistics
- Explosives used: ? 700 tons.
- Seismic impact: 3.8-magnitude event recorded by Lebanon’s National Centre for Geophysics.
- Tunnel network: built over 20 years, described as a “central command compound.”
Official Statements & Responses
- Netanyahu and Katz framed the demolition as a response to Hezbollah’s drone attack and warned residents of northern Israeli towns to open windows before the blast.
- Lebanon’s Ministry of Culture said an assessment of damage to the castle was impossible while the area remained under Israeli occupation.
- ICOMOS Lebanon called for an independent, on-site technical assessment of the castle’s condition.
- A UNESCO spokesperson said the organization had been “informed of the reported incident” and that a technical assessment would be needed to determine any impact on the site’s integrity.
Conflicting Reports & Gaps
- The Israeli Defence Forces asserted that the explosive device that wounded five Lebanese soldiers in the Kfara area was a Hezbollah-deployed device.
- The Lebanese Armed Forces initially reported a “hostile Israeli strike” as the cause of the same injuries.
- The IDF later said it was “not aware of any strikes” against the Lebanese soldiers, leaving the origin of the device unresolved.

Why It Matters
The demolition highlights the clash between military operations and cultural-heritage protection. The blast’s proximity to a UNESCO World Heritage site raises legal and diplomatic questions under the 2024 enhanced-protection designation, which prohibits the use of heritage sites for military purposes. The incident also deepens tensions over the fragile cease-fire between Israel and Hezbollah, with both sides accusing the other of violating the agreement.
