Israel-Hezbollah Ceasefire Holds as US-Iran Deal Faces New Strain

Following the start of the war with US-Israeli attacks on February 28, Iran largely closed the Strait of Hormuz and the US later imposed its own blockade of Iranian ports

Israel and Hezbollah Agree to Ceasefire as US-Iran Deal Hangs in Balance

A fragile ceasefire between Israel and Hezbollah took effect Friday afternoon, a U.S. official confirmed to NBC News, after a dramatic escalation in southern Lebanon killed at least 47 people and threatened to unravel the interim peace deal signed between Washington and Tehran earlier this week. The ceasefire, set to begin at 4 p.m. local time (9 a.m. ET), was announced following urgent diplomatic efforts to salvage the broader U.S.-Iran agreement that President Donald Trump has touted as a historic breakthrough.

An official Hezbollah source told NBC News the group would abide by the truce but accused Israel of continuing to fire and attempting to advance deeper into Lebanese territory. Israeli officials did not immediately comment on the American statement. President Trump, speaking to NBC News by phone Friday afternoon, said he had asked Israel to agree to the ceasefire, calling it "a positive" and "a little icing on the cake." He declined to specify whether he had spoken directly with Prime Minister Benjamin Netanyahu.

The development came after a day of intense violence. According to Lebanon's Ministry of Public Health, Israeli airstrikes since midnight had killed at least 47 people and wounded 97 others. The Israeli military said it struck more than 150 Hezbollah targets and killed dozens of militants in response to what it described as ceasefire violations. Israel also reported that four of its soldiers, including a battalion commander, had been killed in the fighting.

Talks in Switzerland Postponed

The violence had already derailed planned technical talks between the U.S. and Iran, scheduled for Friday at the Bürgenstock Resort in Switzerland. The Swiss Foreign Ministry confirmed early Friday that the talks would not go ahead. Vice President JD Vance canceled his planned travel to Switzerland, and Iran said it would not send its delegation while Israeli attacks on Lebanon continued.

"Switzerland remains ready to facilitate these talks," the ministry said in a statement, adding that "relevant preparatory work" at Bürgenstock was continuing. A regional diplomat with knowledge of the situation told NBC News that Tehran had asked for guarantees that hostilities in Lebanon would end, as outlined in the deal signed with Washington.

Esmail Baghaei, a spokesman for Iran's Foreign Ministry, said the Friday meeting was no longer urgent because the agreement had already been signed, adding that further negotiations would take place as needed.

Why the Ceasefire Matters: The Stakes of the US-Iran Deal

The interim agreement between Washington and Tehran, signed Wednesday, was the product of months of diplomacy following the outbreak of war on February 28, when President Trump announced "major combat operations" against Iran, launching massive joint U.S.-Israeli strikes. The memorandum of understanding includes a provision that all fighting on all fronts, including Lebanon, must end immediately. Israeli strikes in southern Lebanon, therefore, represented a direct challenge to the deal's core terms.

The violence in Lebanon also risked alienating Iran at a critical moment. Tehran has responded bullishly to what it perceives as Trump's eagerness to conclude a war that has become increasingly unpopular in the United States. Mohammad Bagher Ghalibaf, Iran's chief negotiator, said Friday that any talks would remain bound by Tehran's "red lines," with a halt to Israeli attacks on Lebanon being a key demand. "If the enemy seeks to be excessive, we have proven that our fingers are on the trigger and we have no hesitation in giving a crushing response to the enemy," Ghalibaf said, according to the official IRNA news agency.

Despite the strong rhetoric, Iran also signaled flexibility on Friday. The Persian Gulf Strait Authority announced it would waive planned fees for ships passing through the Strait of Hormuz during the 60-day negotiation period designated under the MoU. Ships would be required to provide 48 hours' notice and coordinate routes and transit times, but the waiver aimed to ease tensions over the strategic waterway, which CENTCOM said saw more than 20 vessels pass through overnight.

Regional Mediators Step In

The postponement of the Switzerland talks prompted an urgent diplomatic scramble. Mediators including Pakistan, Saudi Arabia, and Turkiye agreed to gather for discussions in the Egyptian city of Alamein on Sunday, according to Cairo and Islamabad. Qatar and Switzerland also remained engaged, with the Qatari foreign minister meeting his Swiss counterpart at the Bürgenstock resort on Friday to discuss "diplomatic efforts aimed at promoting security and stability in the region."

The U.S. military, meanwhile, said it had lifted its naval blockade of Iranian ports, a key Iranian demand, and CENTCOM confirmed it would continue to operate in the Strait of Hormuz area to support freedom of navigation.

The Background: From War to Ceasefire

The current crisis traces back to February 28, when President Trump announced the start of major combat operations against Iran. Massive joint U.S.-Israeli strikes targeted military, government, and infrastructure sites across Iran. The war quickly expanded, drawing in Hezbollah and other Iran-backed militias across the region.

After the announcement of a two-week ceasefire in April, initial U.S.-Iran talks in Pakistan failed to reach a peace deal. Trump then extended the ceasefire indefinitely while maintaining a U.S. blockade until negotiations concluded. On Sunday, Trump announced that the U.S. and Iran had reached what he called a "great deal." The memorandum of understanding was read to reporters on Wednesday, and the U.S. and Iranian presidents signed it that day, a White House official said.

The deal reportedly includes provisions for a $300 billion Iran reconstruction fund, a fact that has become a political flashpoint in the U.S. Critics argue the fund rewards Iranian aggression, while supporters say it is necessary to stabilize the region and ensure the deal's durability.

Israel's Calculations

Israel has consistently maintained that it must continue military operations against Hezbollah, including airstrikes and occupation of territory in southern Lebanon, to prevent attacks into northern Israel. In response to the news that Hezbollah had killed four soldiers, far-right Israeli Minister of National Security Itmar Ben-Gvir wrote on social media: "All of Lebanon must burn." Finance Minister Bezalel Smotrich called for Israel to "open the gates of hell."

The toughness of Israel's position reflects deep divisions within the U.S.-Israel alliance. President Trump, in a newly released interview clip with Axios, said he has to keep Israel and Prime Minister Netanyahu "sane." "If it weren't for Donald Trump and Bibi Netanyahu -- who I work well with -- but he will tell you: we're the ones with the guns, we're the ones with the whole deal, we're the ones with the B2 bombers, etc. If it weren't for Donald Trump, Israel would have been eviscerated," Trump said.

Perspective: What This Changes

The ceasefire between Israel and Hezbollah, if it holds, removes the most immediate obstacle to the U.S.-Iran peace process. But the fragility of the truce and the underlying tensions suggest the path to a permanent agreement remains highly uncertain.

For the broader region, the deal represents a potential turning point. The reopening of the Strait of Hormuz, the lifting of the naval blockade, and the establishment of a 60-day negotiation period create a framework for de-escalation that could reduce the risk of a wider war. The involvement of multiple mediators -- Qatar, Switzerland, Pakistan, Saudi Arabia, Turkiye, and Egypt -- indicates a broad international desire to stabilize the region.

However, the situation on the ground in Lebanon remains volatile. Hezbollah's accusation that Israeli forces continued firing even after the ceasefire deadline underscores the deep mistrust between the parties. The Israeli military's statement that it had struck more than 150 Hezbollah targets and killed dozens of its members suggests that both sides are preparing for further confrontation if diplomatic efforts falter.

The postponement of the Switzerland talks also highlights the difficulty of coordinating technical negotiations while active hostilities continue. Iran's insistence on linking the Lebanon front to the broader deal could become a recurring point of tension, particularly if Israel resumes operations.

Economic Implications

The renewed stability has already had economic ripple effects. Mortgage Rates Hit One-Month Lows as Iran Peace Deal Boosts Bond Markets, reflecting investor optimism that a broader peace could reduce geopolitical risk and lower energy costs. The waiver of Strait of Hormuz transit fees, combined with the lifting of the naval blockade, signals that trade and energy flows could normalize, potentially easing inflationary pressures globally.

For Iran, the deal offers a path to economic relief after months of crippling sanctions and blockade. The $300 billion reconstruction fund, though controversial, represents significant investment in rebuilding Iranian infrastructure devastated by the U.S.-Israeli strikes.

For Israel, the ceasefire with Hezbollah, even if temporary, provides a respite from rocket attacks and allows the military to consolidate its gains in southern Lebanon. But the far-right elements within Netanyahu's coalition have made clear they view the current arrangement as insufficient.

What Comes Next

The immediate focus now shifts to the Alamein talks on Sunday, where mediators will attempt to bridge the gaps between the U.S., Iran, and Israel. The key issues remain: a permanent cessation of hostilities on all fronts, the withdrawal of Israeli forces from Lebanon, and the timing of sanctions relief and reconstruction funding.

President Trump's ability to manage his relationship with Prime Minister Netanyahu will be crucial. Trump's claim that he can "keep Israel sane" suggests he is prepared to exert pressure, but the limits of that influence remain untested. Iran, sensing Trump's desire for a deal, is likely to press for maximum concessions, particularly on the Lebanon issue.

The ceasefire announced Friday is a positive step, but as the events of the past 24 hours have shown, it can unravel quickly. The world will be watching to see whether this fragile pause can hold long enough to build something more permanent.
