Shockwaves from the explosions registered 3.8 on seismic monitoring scales. Lebanese authorities have denied Israeli claims that there are ‘Hezbollah tunnels’ under the nearly 900-year-old UNESCO World Heritage site.

Israel carried out massive detonations involving around 700 tons of explosives around Lebanon’s historic Beaufort Castle – a UNESCO World Heritage site – with the huge blasts being heard across large parts of the country’s south late on 30 July.
The violent detonations were carried out under the pretext of alleged Hezbollah infrastructure under the Crusader-era fortress. This has been denied by Lebanese authorities.
“Israeli forces carried out unprecedented bombardment in southern Lebanon, triggering a series of powerful explosions that residents said were unlike anything heard in recent years,” Al Manar TV reported on Friday.

Lebanon’s National News Agency (NNA) also reported the blasts, calling them “massive” and “unprecedented,” while confirming that they were heard across the whole south.
“The blasts echoed across all of south Lebanon with unprecedented intensity, and their shockwaves reached the Iqlim al-Kharroub and Khaldeh regions,” the report said, adding that “violent explosions in the Beaufort Castle area shattered the glass of several windows in homes in the town of Qlayaa.”

Lebanese Parliament Speaker Nabih Berri condemned the violent detonations.
“The shockwaves from these terrorist explosions, caused by 700 tons of explosives, registered 3.8 on seismic monitoring scales and were felt by Lebanese citizens from the South and Mount Lebanon all the way to the outskirts of Beirut,” he said.
Lebanon’s Culture Ministry released a statement saying Beaufort Castle was unharmed.
However, it stressed that because the area remains under Israeli occupation, specialized technical teams have been prevented from accessing the site in order to conduct a proper assessment of any potential damage.
Earlier in July, the castle had been placed on UNESCO’s list of sites “in danger.”
The massive detonations were announced by Israeli Prime Minister Benjamin Netanyahu and Israel’s War Ministry late on Thursday evening.
In a joint statement, Netanyahu and War Minister Israel Katz claimed a Hezbollah tunnel network under the castle was destroyed.
They also confirmed the unprecedented amounts of explosives used in their “operation.”
Israeli occupation forces will “remain in the security zone in southern Lebanon and will continue to destroy all terror infrastructure to prevent any attempt by Hezbollah to restore its capabilities,” they added.
Lebanon’s Directorate General of Antiquities has previously rejected Israeli claims that the site contained Hezbollah infrastructure.
Israeli maps and videos detailing “terrorist infrastructure” are fabricated, and the fortress has been under Lebanese state administration since 2000, placing under enhanced protection in line with the 1954 Hague Convention.
Lebanese geologists have warned that demolitions of this scale near major fault lines could potentially trigger human-induced seismic activity.
Israeli forces occupied the castle in May 2026 and framed the move as a major strategic victory. Hebrew media challenged this narrative at the time.
Israeli forces were unable to maintain a consistent presence in the historic site due to constant resistance operations – namely Hezbollah’s FPV drone strikes that have inflicted heavy casualties and losses on the Israeli occupation forces since March.

Since the violent detonations near the castle on Thursday night, Israel has continued destroying civilian infrastructure across south Lebanon.
Heavy explosions were recorded in Deir Siryan on Friday, while Israeli shelling continued to target the Ali al-Taher Hill.
Over 4,300 have been killed and more than a million displaced by Israel in Lebanon since 2 March.
Tens of thousands of civilian homes and buildings – amounting to practically all of south Lebanon’s border villages – have been eradicated.
Israeli occupation forces refuse to withdraw, and the Lebanese government has signed a US-brokered deal allowing Tel Aviv to maintain its illegal presence in the country.
