Massive explosions carried out by the Israeli military to destroy a Hezbollah tunnel network have once again highlighted the risks posed by the Iran-backed group's military infrastructure embedded beneath civilian areas in southern Lebanon.

According to Lebanese media reports, the explosions targeted an underground tunnel on Sunday, causing extensive destruction in the border villages of Majdal Zoun and Mansouri. The blast was so powerful that it reportedly split part of Majdal Zoun geographically into two sections, leaving widespread devastation and preventing residents from returning to their homes.

The Israeli military announced that it had destroyed a 200-meter-long Hezbollah tunnel in southern Lebanon after informing the United States in advance of the operation. The tunnel was reportedly packed with approximately 80 tons of explosives.

Observers say the operation illustrates how parts of southern Lebanon have become military frontlines, weapons storage sites, and tunnel networks situated beneath civilian homes, exposing local communities to severe risks and widespread destruction during military operations.

Lebanon's state-run National News Agency reported that numerous homes in both villages were damaged or destroyed. The agency added that Majdal Zoun has been completely evacuated, while only a few families remain in neighboring Mansouri.

Images circulating online showed extensive devastation, with entire neighborhoods reduced to rubble as underground infrastructure collapsed beneath residential areas. Witnesses reported that the force of the explosion erased property boundaries and landmarks, making it difficult for residents to identify the locations of their homes.

The developments come as Israel and Lebanon recently agreed to a U.S.-brokered framework aimed at ending hostilities. The agreement envisions a gradual Israeli withdrawal from southern Lebanon following the disarmament of non-state armed groups and the restoration of Lebanese army control over the region.

Hezbollah Secretary-General Naim Qassem rejected the agreement, describing it as "invalid," a "humiliation," and a surrender of Lebanese sovereignty. He argued that the framework should instead be replaced by the recent U.S.-Iran understanding reached in Switzerland.

Qassem further stated that any attempt to link an Israeli withdrawal from southern Lebanon to Hezbollah's disarmament crosses "all red lines," accusing Lebanese authorities of legitimizing a prolonged Israeli presence in the country.

The framework agreement, signed under U.S. sponsorship, outlines a path toward permanent peace, direct negotiations between Israel and Lebanon, the gradual deployment of the Lebanese army, Hezbollah's disarmament, international support for reconstruction efforts, and Israel's declaration that it has no territorial ambitions in Lebanon.

On Monday, the Israeli military stated that its war efforts were not over and that preparations for future stages of combat continue, marking 1,000 days since the outbreak of regional hostilities.
