BEIRUT — Israeli forces carried out a series of detonations overnight near the Unesco-listed Beaufort castle in southern Lebanon, Lebanese state media reported Friday, with Israel saying it had destroyed tunnels used by the Iran-backed Hezbollah militant group.

“Israeli forces triggered very powerful explosions around midnight,” specifically “in the area of the Beaufort fortress,” the official National News Agency (NNA) said.

The Crusader-era castle, located in the southern area occupied by Israel, was added last week to Unesco’s List of World Heritage in Danger.

An AFP correspondent in a nearby village reported hearing large explosions.

In a joint statement, Israeli Prime Minister Benjamin Netanyahu and Defence Minister Israel Katz announced that the army had destroyed “terror tunnels in the Beaufort area” using approximately 700 tonnes of explosives.

They said the explosions came after a “blatant violation of the ceasefire agreement” by Hezbollah on Wednesday.

The Israeli army accused Hezbollah of violating their fragile ceasefire by launching an explosive drone at an Israeli military vehicle in southern Lebanon.

Hezbollah has not claimed any attack on Israel since June 20.
