The announcement came a day after talks in Pakistan ended without agreement, underscoring persistent divisions over terms to end a conflict launched on Feb. 28 by the United States and Israel. The blockade is aimed at pressuring Iran to reopen the Strait of Hormuz and accept a broader settlement addressing its nuclear and missile programs, as well as its regional activities.

Trump indicated that diplomatic channels remain open, saying Iran had reached out to explore a possible resolution. “We’ve been called by the right people … and they want to work a deal,” he told reporters outside the White House.Iran signaled conditional openness to negotiations.

Judiciary chief Gholam Hossein Mohseni Ejei said discussions must proceed on the basis of “principles and logic,” while other officials warned that Tehran would respond if the situation escalates.The blockade drew sharp reactions from Iran, which threatened countermeasures targeting ports across the Arabian Gulf and Gulf of Oman, raising the risk that the two-week ceasefire declared earlier could collapse before its April 22 expiry.

At the core of the dispute remain differences over Iran’s nuclear program and control of the Strait of Hormuz, a critical global energy corridor through which roughly one-fifth of the world’s oil supply typically passes. Its closure has already disrupted markets and driven up oil prices.

U.S. Vice President JD Vance, who led the American delegation in the recent talks, said Iran had not provided assurances it would refrain from pursuing nuclear weapons capability. Tehran has long denied such intentions while defending its right to civilian nuclear development, including uranium enrichment.

Iran’s negotiating position, articulated by Parliament Speaker Mohammad Bagher Qalibaf, emphasized sovereignty over the strait, an end to hostilities, and compensation for wartime damage.

Iranian officials also dismissed the blockade as exaggerated, with parliamentary spokesperson Ebrahim Rezaei describing it as “more bluffing than reality.”Pakistan has indicated it may facilitate further dialogue, with Foreign Minister Ishaq Dar expressing willingness to host another round of talks, though no timeline has been confirmed.

Both sides have maintained firm public positions, with Trump warning that any Iranian attempt to challenge the blockade would be met with force, while Iranian foreign ministry spokesperson Esmaeil Baqaei said the measure risked further destabilizing the global economy.

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.

Two Pakistani officials, speaking on condition of anonymity, said Islamabad has offered to again facilitate negotiations, although the final venue would depend on whether Washington or Tehran request an alternative location.

They described the initial round of talks as part of an ongoing diplomatic process rather than a one-off effort.The proposal follows marathon negotiations held on April 12 that ended without a breakthrough but were marked by what U.S. Vice President JD Vance described as “some progress,” particularly on Washington’s demands regarding Iran’s nuclear program.

In an interview with Fox News, Vance said Iranian negotiators had moved closer to U.S. positions on the removal of nuclear material and mechanisms to prevent future uranium enrichment, but were unable to finalize a deal, suggesting decisions may require approval from authorities in Tehran.

“There really is, I think, a grand deal to be had here,” Vance said, adding that the next step rests with Iran.The White House did not confirm whether preparations for a second round are underway. Press Secretary Karoline Leavitt reiterated that U.S. negotiating positions remain unchanged and pointed to increased pressure on Iran following the implementation of a U.S. naval blockade.

Multiple sources familiar with the discussions said both sides are considering further in-person talks aimed at reaching an agreement before the ceasefire expires next week. While Islamabad remains a leading candidate to host the meeting, other locations such as Geneva are also under consideration, with timing still undecided but potentially within days.

A diplomat involved in mediation efforts said there is growing alignment on holding another round, though details on the level of representation and agenda remain unresolved.U.S. President Donald Trump said earlier that Iran had reached out seeking a deal, underscoring continued engagement between the two sides even as tensions persist.

In a telephone conversation, Lavrov stressed the importance of preventing a return to armed confrontation and reiterated that the conflict has no military solution, according to the ministry’s statement.

The call followed recent talks between the United States and Iran in Pakistan, which ended without agreement. Araqchi briefed Lavrov on the discussions, the ministry said, providing details of negotiations that failed to produce a settlement.

Russia has positioned itself as a potential mediator in the conflict, signaling willingness to engage diplomatically as tensions remain high despite a temporary ceasefire and ongoing international efforts to restart negotiations.

Both sides have maintained firm public positions, with Trump warning that any Iranian attempt to challenge the blockade would be met with force, while Iranian foreign ministry spokesperson Esmaeil Baqaei said the measure risked further destabilizing the global economy.

Pakistan’s Foreign Minister Ishaq Dar said it was “imperative” that both parties maintain their ceasefire commitments, adding that Islamabad would continue facilitating dialogue between Washington and Tehran following the inconclusive talks.

U.S. Vice President JD Vance, who led the American delegation, said the absence of a deal was “bad news for Iran much more than it’s bad news for the United States,” reiterating Washington’s demand for a firm commitment from Tehran not to pursue nuclear weapons capability.

He said the United States had made its “red lines” clear, including preventing Iran from acquiring both nuclear weapons and the means to rapidly develop them.

Iranian officials rejected the U.S. position, with state-linked Tasnim news agency reporting that “excessive” American demands had hindered progress. Tehran signaled that discussions would continue, with technical teams expected to exchange documents in follow-up engagements.

Iran’s parliamentary speaker Mohammad Baqer Qalibaf said the U.S. had failed to build trust during the talks despite what he described as “forward-looking” proposals from the Iranian side. He emphasized longstanding skepticism rooted in past negotiations, saying Washington must demonstrate credibility before progress can be made.

Iran’s foreign ministry also downplayed the outcome, stating that no agreement had been expected in a single session and expressing confidence that diplomatic contacts would continue with Pakistan and other regional actors.

Former Iranian foreign minister Mohammad Javad Zarif attributed the breakdown to what he called U.S. attempts to “dictate” terms, warning that negotiations with Iran would not succeed under unilateral conditions.

The Islamabad meeting marked the highest-level direct engagement between the United States and Iran in more than a decade and the most senior talks since the 1979 Islamic Revolution.

The discussions were aimed at halting a conflict that began over six weeks ago and has driven up global oil prices while threatening key maritime routes.Central to the negotiations was the Strait of Hormuz, a critical chokepoint for roughly one-fifth of global energy supplies.

The U.S. military said it was preparing to ensure safe navigation through the waterway, including mine-clearing operations, while Iranian state media denied any U.S. naval transit in the area.

Tehran has demanded control over the strait, war reparations, and broader ceasefire arrangements extending to regional theaters including Lebanon. U.S. officials have focused on securing freedom of navigation and curbing Iran’s nuclear enrichment capabilities.

The talks took place under tight security in Islamabad, where thousands of paramilitary forces were deployed. Pakistani officials described fluctuating tensions during the discussions, with “mood swings” and intermittent progress reported by sources familiar with the negotiations.

The Iranian delegation, which arrived dressed in black to mourn those killed in the conflict, also raised concerns about a U.S. airstrike on a school near a military compound, an incident the Pentagon has said is under investigation.

Despite the impasse, analysts noted the seniority and size of the Iranian delegation as an indication of Tehran’s willingness to engage, even as deep mistrust continues to define the diplomatic landscape.

U.S. President Donald Trump said the agreement followed mediation efforts led by Pakistan, adding he would suspend threats of military action if Iran upheld the ceasefire and ensured full reopening of the Strait of Hormuz.

Pakistan’s Prime Minister Shehbaz Sharif said Islamabad would host talks between U.S. and Iranian delegations on Friday, describing both sides as constructively engaged. He expressed hope that the proposed “Islamabad Talks” would lead to sustainable peace.

China said it welcomed the ceasefire, with foreign ministry spokeswoman Mao Ning stating Beijing would continue efforts to restore stability in the Middle East.Iraq’s foreign ministry also supported the development, calling for “serious and sustainable dialogue” to address underlying disputes and build trust between the parties.

Turkiye backed the planned negotiations in Islamabad and stressed the importance of full implementation of the ceasefire on the ground, while Australia thanked mediators including Pakistan, Egypt, Turkiye and Saudi Arabia for their role in de-escalation efforts.

Egypt underscored the need to respect sovereignty and territorial integrity across the region, particularly for Gulf Cooperation Council countries and Jordan, warning against any violations that could threaten regional stability.

The United Nations welcomed the ceasefire, with Secretary-General Antonio Guterres urging all parties to comply with international law and uphold the terms of the agreement to pave the way for comprehensive peace.Indonesia also called for respect for sovereignty and diplomacy, while Germany’s foreign minister described the truce as a critical first step toward avoiding further escalation.

British Prime Minister Keir Starmer said the ceasefire would bring “a moment of relief” and confirmed plans to engage Gulf partners on ensuring the permanent reopening of the Strait of Hormuz.

Financial markets responded positively to the announcement, with oil prices falling and global stocks rising after Iran agreed to allow safe passage through the key waterway, which carries a significant share of the world’s energy supplies.

Iran and the United States have agreed to a conditional two-week ceasefire, marking a temporary pause in hostilities that have disrupted regional stability and threatened global energy supply routes, according to statements from officials in both countries and mediators involved in the talks.

The agreement provides for an immediate halt to attacks and the reopening of maritime traffic through the Strait of Hormuz, a critical corridor for global oil shipments. Iranian authorities said safe passage would be coordinated with their armed forces during the ceasefire period, indicating continued operational control over the waterway.

The announcement was confirmed by Shehbaz Sharif, who said the ceasefire would apply “everywhere including Lebanon and elsewhere” and take effect immediately. Sharif also invited both sides to send delegations to Islamabad for talks aimed at reaching a longer-term settlement, positioning Pakistan as a key mediator in the process.

Officials in Washington and Tehran offered differing emphases on the agreement. Donald Trump described the ceasefire as a “total and complete victory” for the United States, stating that US military objectives had been achieved and that discussions toward a broader peace arrangement were already advanced. He added that Washington would suspend further military action, including previously stated threats against Iranian civilian infrastructure, contingent on compliance with the terms of the agreement.

Iranian Foreign Minister Seyed Abbas Araghchi confirmed that Tehran would halt what he described as “defensive operations” to facilitate negotiations. He said Iran had submitted a 10-point proposal that Washington had accepted as the basis for talks, while also reviewing a separate 15-point proposal put forward by the United States.

Despite these developments, there were inconsistencies in how the ceasefire’s geographic scope was described. Benjamin Netanyahu stated that the agreement did not extend to Lebanon, contradicting assertions by Pakistani officials and some US sources that the ceasefire would apply across multiple fronts. The discrepancy highlights ongoing uncertainty over the terms and implementation of the arrangement.

No official text of either proposal has been publicly released. However, details reported by Iranian state media suggest that Tehran’s 10-point plan includes provisions for maintaining its authority over the Strait of Hormuz, securing the lifting of sanctions, unfreezing overseas assets, and obtaining compensation for damages.

The proposal is also reported to call for the withdrawal of US forces from the region, recognition of Iran’s nuclear enrichment activities, and a binding United Nations resolution to formalize any final agreement.

Iranian diplomatic messaging has reinforced these positions, emphasizing continued control over strategic waterways and a cessation of hostilities across multiple regional theaters. Tehran has also indicated that any lasting agreement would need to address broader geopolitical and economic demands, including sanctions relief and security guarantees.

By contrast, the US proposal is reported by regional sources cited by CNN to focus on nuclear and security constraints. The 15-point framework is believed to include commitments by Iran to forgo nuclear weapons development, surrender highly enriched uranium, limit its defense capabilities, and curtail support for regional proxy groups. It also includes provisions to ensure the continued operation of the Strait of Hormuz as an open international shipping route.

Iran has previously rejected these terms, describing them as “excessive, unrealistic and unreasonable,” suggesting that significant gaps remain between the two sides despite the temporary ceasefire.The reopening of the Strait of Hormuz is a central component of the agreement, given its importance to global energy markets.

Any disruption to shipping through the waterway has immediate implications for oil prices and supply chains, making the ceasefire’s maritime provisions a key focus for international stakeholders.

The two-week timeframe underscores the provisional nature of the arrangement, with both sides framing the ceasefire as an opportunity to advance negotiations rather than a definitive resolution. Diplomatic engagement is expected to intensify in the coming days, particularly with the proposed talks in Islamabad.

While the agreement signals a de-escalation after a period of heightened tensions, the absence of a publicly verified framework and conflicting statements from key actors point to a fragile understanding that will depend on sustained diplomatic coordination and adherence to interim commitments.

Iran has rejected a U.S. ultimatum to reopen the Strait of Hormuz by a deadline set by former U.S. President Donald Trump, as military strikes intensified and diplomatic efforts led by Pakistan approached what officials described as a critical stage.

With hours remaining before the deadline, a senior Iranian source said Tehran would not reopen the strategic waterway without concessions from Washington that had not been offered. The Strait of Hormuz, a key global energy corridor, has effectively been closed by Iran to most international shipping since late February following joint U.S.-Israeli military actions.

Trump warned that failure to comply would result in large-scale destruction of Iranian infrastructure, including power grids and bridges. In a social media post, he stated that “a whole civilization will die tonight,” framing the moment as a pivotal point in global history.

The remarks drew criticism from legal experts, including a former U.S. State Department adviser now with the International Crisis Group, who said the language could be interpreted as a threat violating international norms.

Military activity escalated across Iran throughout the day. Strikes were reported on transport infrastructure, including railway and highway bridges, as well as an airport and a petrochemical facility. U.S. forces also targeted installations on Kharg Island, which hosts Iran’s primary oil export terminal.

Power outages were reported in parts of Karaj following damage to transmission lines and a substation.Iran signalled a broadening of its response. Officials warned that Gulf states aligned with Washington could face retaliatory strikes on critical infrastructure.

A senior Iranian source said such actions could disrupt electricity and water supplies in desert cities dependent on energy systems.Iran’s Revolutionary Guards issued a statement saying previous restraint had ended and that Tehran would seek to deprive the United States and its regional allies of oil and gas resources.

Iranian authorities also claimed responsibility for attacks on a vessel in the Gulf and on a major Saudi petrochemical facility in Jubail, where international energy companies operate.In parallel, reports emerged of an overnight strike on a synagogue in Tehran, which Iranian officials attributed to Israeli forces.

Footage aired by state media showed debris scattered across the site, including religious texts. Israel’s military did not immediately comment on the incident.Diplomatic efforts led by Pakistan continued amid the escalation.

Iranian officials said mediation attempts were “approaching a critical, sensitive stage,” with Islamabad relaying messages between the two sides. A proposal under discussion included a temporary ceasefire and partial reopening of the strait, with broader negotiations to follow.

However, Iranian sources said Tehran had rejected interim arrangements, insisting instead on a permanent cessation of hostilities, guarantees against future attacks and compensation for damage.Iran’s conditions, as outlined through official channels, also included maintaining control over the strait and introducing a mechanism to regulate transit, potentially involving fees.

Prior to the conflict, the waterway functioned as an open international route through which roughly one-fifth of global oil and liquefied natural gas supplies passed.Despite the intensifying conflict, global markets showed limited reaction, reflecting uncertainty over whether the U.S. would carry out the threatened escalation.

Trump has previously issued similar warnings but later stepped back, citing unspecified progress in talks, claims that Iranian officials have denied.On the ground, residents expressed concern over the prospect of further escalation.

A resident in Isfahan said she hoped the latest threats would not materialise, reflecting broader public anxiety as military actions continued.Iran maintains that any negotiations must follow a halt to U.S. and Israeli strikes and include the lifting of sanctions.

Without such measures, officials indicated that Tehran would continue its current posture, including restrictions on maritime transit through the Strait of Hormuz.

As the deadline approached, neither side signalled a willingness to compromise, raising the risk of further escalation in a conflict that has already disrupted regional stability and global energy flows.

Ishaq Dar said after meetings with regional counterparts that Islamabad was ready to facilitate “meaningful talks” toward a “comprehensive and lasting settlement,” including potential U.S.-Iran negotiations. It was not immediately clear whether either side had agreed to participate.

Iran’s parliament speaker Mohammad Baqer Qalibaf accused Washington of signalling openness to diplomacy while preparing for military escalation, saying Tehran would not accept demands amounting to surrender.U.S. officials have not publicly confirmed any agreement to attend talks.

Reports cited by U.S. media indicate the Pentagon is assessing options that could include ground operations, though no final decision has been announced by Donald Trump.

Discussions among regional powers, including Saudi Arabia, Turkey and Egypt, have focused on reopening the Strait of Hormuz, where Iranian restrictions on shipping since late February have disrupted global oil flows.

The conflict has driven oil prices sharply higher and intensified risks to maritime trade, with additional threats emerging near the Bab el-Mandeb Strait following attacks by Iran-aligned Houthi forces.

Israel said it carried out more than 140 air strikes across Iran over a 24-hour period, targeting missile infrastructure and other sites. Iranian media reported damage to Mehrabad airport in Tehran and a petrochemical facility in Tabriz.

Missile and drone exchanges have extended beyond Iran, with strikes reported in southern Israel near Beersheba and damage to industrial facilities in Gulf states including the United Arab Emirates and Bahrain.

The International Atomic Energy Agency said Iran’s heavy water production plant at Khondab had suffered severe damage and was no longer operational, though it contained no declared nuclear material.

The U.S. military has begun deploying thousands of Marines to the region, with the first contingent arriving aboard an amphibious assault ship, according to official statements.

Washington last week proposed a ceasefire framework that included reopening Hormuz and limiting Iran’s nuclear programme, but Tehran rejected the plan.

The conflict has triggered domestic political divisions in the United States, with protests reported in multiple cities and lawmakers offering sharply differing views on the war’s trajectory.
