A ceasefire in Lebanon appeared to hold largely intact on Monday, marking the longest pause in fighting since the onset of hostilities three months ago between Hezbollah and Israeli forces, though concerns about renewed violence have kept many displaced residents from returning to their homes.

According to a senior Lebanese security official, adherence to the truce has been “almost total” since it began Saturday evening. However, the official noted isolated incidents, including fire from an Israeli tank targeting a village near Tyre, the use of sound grenades by Israeli forces at two other locations, and the operation of an Israeli drone over Beirut.

The broader conflict has underscored tensions surrounding the interim U.S.-Iran negotiations aimed at ending regional hostilities. Iran announced over the weekend that it had closed the strategically vital Strait of Hormuz, accusing the U.S. of failing to uphold its commitment to halt the fighting in Lebanon. On Monday, U.S. Vice President JD Vance, who heads Washington’s delegation for talks with Iran, stated that progress had been made toward ending the violence in Lebanon and confirmed that the Strait of Hormuz remained open.

Vance described Lebanon’s situation as “a work in progress,” reflecting ongoing uncertainty despite the ceasefire’s relative success so far.

Hospital officials in the south of Lebanon, a region heavily battered in recent months, reported a period of calm. Hassan Wazni, director of a hospital in Nabatieh, said the lull had persisted since Saturday evening, calling it the longest sustained ceasefire since the conflict began. “I’m monitoring the situation day by day, and most of the time I’m sleeping in the hospital,” Wazni said. The sense of respite in Nabatieh contrasts with widespread displacement and damaged infrastructure across southern Lebanon.

While the truce offers a temporary relief, the presence of minor flare-ups and lingering mistrust between the parties involved suggests that the ceasefire’s durability remains uncertain. Displaced civilians continue to exercise caution amid fears that the fragile calm could unravel. The ongoing diplomatic efforts between the U.S. and Iran, alongside local security dynamics, will likely play a critical role in determining whether the region can sustain a longer-term peace.
