Speaking during a visit to India, US Secretary of State Marco Rubio said an announcement could come within days as diplomatic efforts intensified.

“There is a chance that, whether it’s later today, tomorrow, in a couple days, we may have something to say,” Rubio told reporters, adding that he hoped to deliver “good news” soon.

Iranian officials also pointed to momentum in the talks. Foreign Ministry spokesman Esmaeil Baqaei said negotiators were working on a memorandum of understanding consisting of 14 clauses that could serve as the basis for a broader settlement.

“Our intention was first to draft a memorandum of understanding, a kind of framework agreement composed of 14 clauses,” Baqaei said on state television, while cautioning that a trend toward rapprochement did not guarantee agreement on all major issues.

Iranian officials stressed that disputes surrounding Tehran’s nuclear program would not form part of the initial framework, which is expected to focus on de-escalation measures and ending hostilities. Iranian negotiators have also said lifting the US naval blockade remains a key component of discussions.

The latest diplomatic push has been heavily supported by Pakistan, whose army chief, Asim Munir, concluded a two-day visit to Tehran after meetings with President Masoud Pezeshkian, Parliament Speaker Mohammad Bagher Qalibaf, Foreign Minister Abbas Araghchi and Interior Minister Eskandar Momeni.

Pakistan’s military said the meetings contributed “meaningfully” to mediation efforts and produced encouraging progress toward a final understanding.
“The discussions remained focused upon expediting the consultative process underway to support peace and stability in the region and to reach a conclusive agreement,” Pakistan’s military said in a statement following Munir’s departure.

Despite the positive signals, Iranian officials continued to warn against any return to military confrontation. Qalibaf said Iran’s armed forces had rebuilt their capabilities during the ceasefire period and would respond forcefully if hostilities resumed.

The conflict erupted after US and Israeli attacks on Iran on Feb. 28, triggering a regional crisis that disrupted shipping and energy flows through the strategically important Strait of Hormuz, a vital route for global oil exports.

Araghchi, in a conversation with Antonio Guterres, said Iran remained engaged in diplomacy despite what he described as repeated military aggression and excessive demands from Washington. He also held consultations with counterparts from Turkiye, Iraq, Qatar and Oman.

Meanwhile, US President Donald Trump spoke by phone with Sheikh Tamim bin Hamad Al Thani, whose office said the Qatari leader supported efforts to contain the crisis through dialogue and diplomacy.

Any agreement would mark the most significant diplomatic breakthrough since the outbreak of the conflict and could ease tensions across a region that has faced months of military escalation and economic disruption.

The proposed accord, details of which were reported by the Saudi-owned broadcaster Al Arabiya, outlines a series of measures aimed at reducing tensions between Washington and Tehran and reinforcing regional stability following months of heightened confrontation.

According to the reported draft, both countries would pledge to abide by international law and the United Nations Charter, underscoring a renewed focus on diplomatic engagement and adherence to established international norms.

A central element of the agreement is the phased easing of U.S. sanctions on Iran. In return, Tehran would be required to fully implement the commitments contained in the accord, Al Arabiya reported.

The draft also includes guarantees for freedom of navigation in the Arabian Gulf, the Strait of Hormuz and the Sea of Oman, waterways that are critical to global energy shipments and international trade.
Both sides would further commit to respecting each other’s sovereignty and territorial integrity and refrain from interference in domestic affairs, according to the reported text.

The agreement contains provisions barring attacks on military, civilian and economic infrastructure, a clause that could help reduce the risk of direct confrontation and disruptions to regional energy markets.
Details regarding Iran’s nuclear programme, a longstanding source of dispute between Tehran and Washington, were not included in the reported draft and remain unclear.

Al Arabiya did not disclose how it obtained the document. Neither U.S. nor Iranian authorities had publicly commented on the reported draft at the time of publication.

The agreement would take effect immediately upon formal announcement by both governments, according to the reported text.

The discussions, held days after a Pakistan-brokered ceasefire, marked the first direct engagement between senior U.S. and Iranian officials since Iran’s 1979 Islamic Revolution. Delegations led by U.S. Vice President JD Vance and Iranian Parliament Speaker Mohammad Bagher Qalibaf met over more than 20 hours at Islamabad’s Serena Hotel, with Pakistani mediators shuttling between the sides.

Despite moments when negotiators appeared close to a framework agreement, talks ultimately stalled over key issues including Iran’s nuclear program, control of the Strait of Hormuz, and access to frozen assets, according to 11 sources familiar with the discussions.

A U.S. official said Washington’s core objective remained ensuring Iran does not obtain a nuclear weapon, while Iranian officials emphasized sovereignty concerns, sanctions relief, and broader security guarantees.

Iran has consistently denied seeking nuclear weapons but maintains its right to uranium enrichment.Sources described a tense and shifting atmosphere, with periods of optimism giving way to deadlock. At one stage, the sides were “80 percent” toward an understanding before unresolved political decisions derailed progress, one source said.

Pakistan played a central mediating role, with Prime Minister Shehbaz Sharif confirming that efforts to bridge differences are ongoing. Officials said communication between Tehran and Washington continues through intermediaries, even after the formal talks ended.

U.S. President Donald Trump said on Monday that Iran had reached out seeking a deal, though this could not be independently verified. A White House spokesperson reiterated that Washington’s position remains unchanged, particularly its demand that Iran abandon any pathway to nuclear weapons.

Iranian officials signaled deep mistrust, citing past negotiations and subsequent military actions, while also indicating willingness to continue discussions under defined conditions.The Strait of Hormuz remains a central point of contention, with Iran asserting control over the waterway and the United States insisting on restoring unrestricted navigation.

The dispute has had significant implications for global energy markets, contributing to volatility and supply concerns.Mediators, including Pakistani officials and regional diplomats, have continued backchannel communications in an effort to revive talks.

Both sides face mounting pressure to de-escalate, with economic costs rising and broader geopolitical risks intensifying.
