A ceasefire largely held in Lebanon on Monday as the country experienced the longest lull in three months of war between Hezbollah and Israel, even as fear of renewed hostilities kept displaced people from going home.

A senior Lebanese security official said adherence to the ceasefire had been "almost total" since Saturday evening, though the official said an Israeli tank fired shells toward a village near Tyre and Israeli forces fired sound grenades in two other locations on Monday. An Israeli drone buzzed over Beirut.

The war has tested the interim U.S.-Iran deal on ending ‌the regional conflict, leading Tehran to announce over the weekend it had once more closed the Strait of Hormuz, saying the U.S. had failed to meet its commitment ​to halt the fighting in Lebanon.

Vice President JD Vance, who led Washington's delegation to a first round of talks with Iran aimed at reaching a final peace deal, said on Monday that progress had been made toward ending hostilities in Lebanon and that the Strait was open.

He said Lebanon ⁠was a work in progress.

Hassan Wazni, director of a hospital in Nabatieh — a city in the south that has been bombarded during the conflict — said there had ​been calm since Saturday evening.

"I'm monitoring the situation day by day, and most of the time I'm sleeping in the hospital. This is the longest a ceasefire has held," ⁠he told Reuters by phone.

But people were hesitant to return, he added, noting that a ceasefire declared on Friday had quickly collapsed, with 20 people in Lebanon killed by Israeli attacks on Saturday, according to Lebanon's civil defense.

"People are still uneasy," Wazni said.

Israeli forces remain deployed ‌deep inside southern Lebanon, occupying a self-declared security zone where they have been razing villages, saying Hezbollah has embedded itself in civilian areas.

Israeli Prime Minister Benjamin Netanyahu said ​on Monday that troops had ‌full freedom of action to thwart any Hezbollah direct or emerging threat against them or Israeli citizens and would remain in Lebanon for "as long as is necessary."
