Following almost four months of conflict in the area, officials from both nations confirmed that an agreement has been finalized between Washington and Tehran. In a televised statement early Monday, Kazem Gharibabadi, serving as deputy foreign minister for Iran, announced that the accord would halt hostilities between the nations and extend to include Lebanon.

Although specific terms of the agreement remained undisclosed, a statement released on Truth Social Sunday night indicated that the president had declared the Strait of Hormuz open and the naval blockade lifted, adding that vessels worldwide could resume operations. Trump announced in the post that he wanted to increase oil production.

The official subsequently stated that access through the strait would depend on the agreement expected to be finalized in Geneva on Friday, as announced by mediator Pakistan, to facilitate mine clearance operations; however, Mehr state news from Iran reported that the understanding reached with the US specifies the waterway would reopen within 30 days under arrangements managed by Iran.

On Sunday afternoon, Prime Minister Shehbaz Sharif of Pakistan revealed the accord, with statements from each party indicating a complete cessation of armed conflict across all territories, encompassing Lebanon. Despite an Israeli attack in Lebanon on Sunday that prompted disapproval from Iran and President Trump, the ceasefire arrangement was reached.

After extensive negotiations, Sharif announced on X that an agreement had been concluded between Washington and Tehran. He noted that the formal signing of the peace accord would likely occur in Switzerland on 19 June.

Following Israel's renewed aerial bombardments of Beirut, Trump advocated for moderation on Sunday while intermediaries worked toward an initial agreement that could bring the three-month Middle Eastern conflict to a close. On Sunday, Trump suggested a potential agreement with Iran was possible, though by day's end in the area, no deal had been finalized.

Officials from Iran indicated they may respond militarily to the strike on Beirut, where an airstrike attributed to Israel leveled a structure in the southern part of the city, resulting in three fatalities and six wounded. Trump told Axios that Israel's military action delayed the deal by a few hours, and he said to Netanyahu that his decision-making was poor.

Israel reported targeting high-ranking Hezbollah officials following the firing of three rockets into its northern territory by the group, which maintains ties with Iran. An operation in Beirut by forces last week led to renewed hostilities between the two nations, briefly affecting ongoing diplomatic discussions.

On Sunday, Iran's parliamentary speaker and a negotiator for Tehran posted on X that Israeli attacks on Beirut indicated the United States either lacked willingness to honour agreements or capacity to enforce them, and noted the attacks might jeopardise ongoing negotiations. According to the official Mizan news agency, the deputy commander of the joint command headquarters stated that a response to the acts would be forthcoming.

Iran's foreign ministry stated the US bears responsibility for Israel's operation in Lebanon and signalled its intention to respond forcefully. The military command stated that forces were prepared to respond to hostile actions.

Iranian officials stated that any ceasefire arrangement would need to encompass the conflict in Lebanon, where military operations have resulted in territorial control of southern areas. Qatari mediators travelled to Tehran on Sunday to complete negotiations on a memorandum of understanding, according to reports from the region.

According to preliminary reports not yet verified, the tentative accord would require Iran to restore full maritime access through the Strait of Hormuz, a waterway that previously transported approximately one-fifth of global oil and liquefied natural gas shipments before hostilities began. Simultaneously, Washington would end its sanctions on Tehran and permit Iranian oil exports, offering economic respite to the country's struggling financial system.

The memorandum omitted the most disputed matters, including Iran's nuclear activities, which were to be negotiated in a subsequent 60-day phase before reaching a broader agreement. Observers have raised doubts about completing complex negotiations within the proposed timeline, pointing out that the 2015 accord between the two nations—which limited Iran's nuclear programme in return for sanctions relief—took almost a decade to finalise and required large teams of expert diplomats, with one researcher from the Atlantic Council noting the difficulty of addressing all issues in the available time.

Within Israel, observers voiced notable unease regarding the preliminary framework, particularly noting the draft's lack of provisions compelling Iran to limit its ballistic missile programme or its backing of regional armed groups like Hezbollah. Netanyahu has expressed support for Trump while confronting electoral challenges in the upcoming vote.

On 2 March, two days following a joint operation by Washington and Tel Aviv that resulted in the death of Iran's supreme leader, Ali Khamenei, the Lebanese militant group launched rocket strikes into Israeli territory. Israeli forces have now advanced further into Lebanon than at any time in more than 25 years, with observers describing the development as a substantial setback.

A complete breakdown.

In the mass-market Maariv newspaper, Avi Ashkenazi stated that Iran has become a primary beneficiary of recent developments. A former national security adviser to Netanyahu described the proposed agreement as an error in judgment.

Republican opponents of the agreement have also voiced concerns about elevated fuel costs and the ongoing conflict prior to midterm voting.

Experts predict that global economic recovery will lag even if shipping access through the Strait of Hormuz resumes. Ensuring safe transit for vessels currently stranded in the restricted channel remains uncertain, and damaged facilities from the fighting will require several months of complete restoration.

The former president is anticipated to address clearance of mines from the waterway at the G7 gathering commencing Monday.
