A day after President Trump announced a potential deal with Iran, Lebanon found itself in a familiar position — waiting on outside powers to determine whether the latest war to devastate the country was drawing to an end.

After Hezbollah, the Iranian-backed Lebanese militant group, fired on Israel in March in solidarity with its patron, the country was dragged into a conflict that has killed more than 3,000 people and displaced hundreds of thousands.

A U.S.-brokered cease-fire took effect on April 17, but Israel and Hezbollah have continued to clash, with each side accusing the other of violating the truce. The fighting has escalated in recent weeks, exposing the limits of the cease-fire and stoking fears that the conflict could turn into yet another full-blown war.

On Sunday, Lebanon hoped that the agreement announced by Mr. Trump could bring a degree of calm after months of intense upheaval. While the terms of the agreement are murky, three senior Iranian officials told The New York Times that it would halt the fighting on all fronts, including Lebanon.

On Sunday, a senior U.S. official said that the United States and Iran had agreed to a preliminary deal that would fully reopen the Strait of Hormuz and see Iran dispose of its stock of highly enriched uranium. He cautioned that a deal had not been signed and would have to be approved by Mr. Trump and Mojtaba Khamenei, Iran’s supreme leader.

Many of the most intractable problems between the countries, including the future of Iran’s nuclear program, were put off to future negotiations. Iran’s leaders and official state media had not publicly commented on Sunday on what was in the potential agreement or what specific issues were under discussion.
