The United Nations has expressed serious concern over Israel's continued large-scale demolitions in southern Lebanon, warning of a "devastating impact on civilian infrastructure, cultural heritage, and the collective memory of communities." The statement, issued on Saturday 1 August by the office of the UN special coordinator for Lebanon, came after overnight detonations near Beaufort Castle — a Crusader-era fortress that was added just last week to UNESCO's List of World Heritage in Danger.

Israeli Prime Minister Benjamin Netanyahu and Defence Minister Israel Katz confirmed that the Israeli military used approximately 700 tonnes of explosives to destroy what they described as "terror tunnels in the Beaufort area." Israel said the operation was a direct response to what it called a flagrant ceasefire violation by Hezbollah — the Iran-backed Lebanese militant group — which it accused of launching an explosive drone against an Israeli military vehicle earlier in the week. Hezbollah, however, has not publicly claimed any attack on Israel since 20 June, and called on Lebanese authorities to act at "all political and diplomatic levels" to halt what it described as Israeli crimes.

Lebanese President Joseph Aoun condemned the blasts as "an extremely dangerous escalation" and a direct threat to a fragile framework agreement reached in June, brokered with US involvement, which envisions the Lebanese army deploying into southern areas progressively vacated by Israeli forces — contingent on Hezbollah's disarmament, which the group has refused. Lebanon's National News Agency reported several further detonations across the south in the hours that followed, some powerful enough to be felt across wide areas. Lebanese Prime Minister Nawaf Salam separately condemned what he called "continuous Israeli aggressions" including damage to archaeological sites. The Lebanese culture ministry said possible damage to the vicinity of Beaufort Castle could not yet be assessed, as the site remains inaccessible.

The timing has added tension to already delicate diplomacy. A new round of talks between Israel and Lebanon is scheduled to take place in Rome next week, and Aoun warned that the bombings "send negative messages and undermine international efforts aimed at consolidating stability." The UN echoed this concern, stating that "this escalating pattern of destruction must stop as diplomatic channels exist to resolve any outstanding issues."

The broader context remains volatile. The Israeli military said on Saturday that it had killed several Hezbollah fighters inside what it designated a "security zone" in Lebanon, and reported that an Israeli soldier was moderately wounded and evacuated for treatment. Lebanon's army chief, speaking in the south to mark Lebanese army day, declared that "we reject the continued Israeli occupation of any part of our territory." Lebanese authorities say that Israeli military action since the conflict escalated has killed more than 4,300 people in the country — figures that underscore the enormous humanitarian stakes as diplomatic efforts continue.
