U.S. President Donald Trump said on Sunday he had told his representatives not to rush into any deal with Iran, as his administration played down hopes of an imminent breakthrough ​in the three-month-old war that had been raised a day earlier.

The U.S. blockade on Iranian ships in the Strait of Hormuz would “remain in full force and effect until an agreement is reached, certified, and ‌signed,” Trump wrote on Truth Social. “Both sides must take their time and get it right,” he added, Reuters reported.

There was no immediate response from Iran’s government. But Tasnim news agency, which is linked to Iran’s Revolutionary Guards, said the U.S. was still obstructing parts of a potential deal, including Tehran’s demand for the release of frozen funds.

A day earlier, Trump said Washington and Iran had “largely negotiated” a memorandum of understanding on a peace deal that would reopen the Strait of Hormuz, which before the conflict carried one-fifth of global oil and liquefied natural gas shipments.

The two sides remain ​at odds on several difficult issues, such as Iran’s nuclear ambitions, Israel’s war in Lebanon with the Iranian-backed Hezbollah militia and Tehran’s demands for the lifting of sanctions and the release of tens of billions of dollars ​of Iranian oil revenues frozen in foreign banks.

WORKING OUT DEAL’S DETAILS

A senior Trump administration official told reporters an agreement would not be signed on Sunday, saying that the Iranian system ⁠did not move fast enough. But he outlined what he said were the latest contours of what was being negotiated.

The official, speaking on the condition of anonymity, said Iran had agreed “in principle” to open the Strait of Hormuz, in exchange ​for the United States lifting its naval blockade, and to dispose of Tehran’s highly enriched uranium.

He said the U.S. understood Iran’s Supreme Leader Ayatollah Mojtaba Khamenei had endorsed the broad template of the deal.

There was no immediate confirmation from Iran or ​elaboration on what an “in principle” agreement meant.

The U.S. official said Washington envisioned first re-opening the strait and lifting the U.S. naval blockade. Negotiating the details of the nuclear measures would take more time, he said.

He pushed back on suggestions that Iran has not accepted disposing of its stockpiled enriched uranium. “It’s a question about how,” the official said.

A second senior administration official said on Sunday that the proposed framework would give negotiators 60 days to reach a final deal.

Iranian sources had told Reuters that in future stages, “feasible formulas” could be found to resolve the ​dispute over its highly enriched uranium stockpile, including diluting the material under the supervision of the U.N. nuclear watchdog.

Iran has long denied U.S. and Israeli accusations that it is pursuing nuclear weapons and says it has a right to enrich uranium ​for civilian purposes, although the purity it has achieved far exceeds that needed for power generation.

DEAL DRAWS OUT U.S. CRITICS

Trump, whose approval ratings have been hit by the war’s impact on U.S. energy prices and who has faced congressional efforts to curb his war powers, has ‌repeatedly played up ⁠the prospect of an agreement to end the conflict that the U.S. and Israel started on February 28. A tenuous ceasefire has been in place since early April.

Oil prices hit two-week lows to kickstart the week with Brent crude futures down over 4% to $98.83 a barrel — the first time it has dipped below $100 in intraday trading since early May — while U.S. West Texas Intermediate was at $92.03 a barrel, also down over 4%.

As details of the possible agreement emerged over the weekend, critics including former Secretary of State Mike Pompeo and Democratic lawmakers argued that it offered little beyond the 2015 Iran nuclear deal negotiated by former President Barack Obama, from which Trump withdrew during his first term.

Chris Van Hollen, a Democratic member of the Senate Foreign Relations ​Committee, said the deal’s reported outlines would amount to ​little more than “the pre-war status quo” with Iran.

“I think ⁠this was a blunder,” Van Hollen said on the “Fox News Sunday” program. “When you’re digging a hole, you should stop digging, and that sounds like maybe what we’re doing finally.”

Trump, who has also faced criticism from hawkish conservatives over his willingness to compromise with Iran, pushed back.

“If I make a deal with Iran, it will be a good and proper one … So don’t ​listen to the losers, who are critical about something they know nothing about,” Trump said in a Truth Social post on Sunday.

In another potential stumbling block, an Iranian ​military adviser to Khamenei said Tehran ⁠had the legal right to manage the Strait of Hormuz, though it was not clear if that meant continuing to decide which ships can go through.

Iran’s Revolutionary Guards said 33 vessels had passed through the strait over the past 24 hours after getting permission from Tehran, still far short of the 140 on a typical day before the war.

Any deal reinforcing the current fragile ceasefire would bring relief to markets but not immediately quell a global energy crisis, which has driven up costs of fuel, fertilizer and food.

Even ⁠if the war ​ends now, full flows through the strait will not return before the first or second quarter of 2027, the head of the Abu Dhabi National ​Oil Company said last week.

The U.S.-Israeli bombing of Iran killed thousands of people in Iran before it was suspended in early April.

Israel has also killed thousands more and driven hundreds of thousands from their homes in Lebanon, which it invaded in pursuit of Hezbollah. Iranian strikes on Israel and neighbouring Gulf ​states have killed dozens.

At least 24 people were killed and nearly 70 injured after a powerful explosion targeted a train carrying military personnel in Balochistan province on Sunday morning, according to officials and local media reports.

The blast occurred shortly after 8am near the Chaman Phatak area of Quetta as the train was travelling from a military zone toward the city’s main railway station.

Authorities said the explosion caused severe damage to the railway track and partially damaged the train. Three coaches, including the locomotive, were derailed while two overturned following the blast.

The impact of the explosion was reportedly heard across Quetta and shattered windows and glass panels in nearby buildings. Several vehicles parked near the scene caught fire, with at least 10 vehicles damaged in the blast. Material damage was also reported in surrounding homes and buildings.

Emergency rescue teams, firefighters and security forces rushed to the scene soon after the attack, cordoning off the area and launching rescue and recovery operations. Firefighters worked to contain flames that spread to nearby vehicles after the explosion.

Authorities later declared an emergency in government hospitals across Quetta, with doctors and medical staff placed on high alert to treat the large number of injured victims.

The separatist militant group Baloch Liberation Army (BLA) claimed responsibility for the attack. In a statement, the group said its Majeed Brigade, described as its suicide attack wing, had targeted security personnel travelling from Quetta Cantonment in what it called a “well-planned fidayee attack”.

The group said further details regarding casualties and damage would be released later.

Following the attack, the Peshawar-bound Jaffar Express was halted at Quetta Railway Station as a precautionary measure.

Pakistan Railways Minister Hanif Abbasi condemned the bombing, describing it as a cowardly act of terrorism aimed at spreading fear and chaos in the country.

Abbasi alleged that anti-Pakistan elements based in India and Afghanistan were involved in attempts to destabilize Pakistan through such attacks. He said railway operations would continue despite the incident and vowed that those responsible would face justice.

Babar Yousafzai, spokesperson for Pakistan’s interior ministry, said all relevant institutions had been placed on high alert following the explosion. He urged residents to avoid gathering near the blast site to allow emergency teams to carry out rescue operations safely.

Counter-terrorism teams and explosives experts later arrived at the scene to begin technical investigations into the nature of the explosive device and identify those responsible.

The bombing is one of the deadliest incidents reported in Balochistan in recent months. The province has long faced insurgent violence, with separatist groups frequently targeting security forces, transport infrastructure and government installations.

A “largely negotiated” memorandum of understanding on an Iran peace deal would reopen the Strait of Hormuz, U.S. President Donald ​Trump said on Saturday, although the Iranian Fars news agency disputed that claim.

Trump posted on social media that the emerging agreement would reopen the strait, the vital shipping passage ‌whose closure has upended global energy markets since the U.S. and Israel launched the war on Iran in February. He did not say what else would be included in an agreement.

“Final aspects and details of the Deal are currently being discussed, and will be announced shortly,” Trump wrote on Truth Social.

But Fars reported early on Sunday that the agreement would allow Iran to manage the strait and that Trump’s assertion on the strait was “inconsistent with reality.”

IRAN’S NUCLEAR PROGRAM IN FOCUS

U.S. news ​website Axios reported late on Saturday that the U.S. and Iran were close to a deal that would reopen the Strait of Hormuz with no tolls during a 60-day ceasefire extension, ​while Iran would be able to freely sell oil and negotiations would be held on curbing Iran’s nuclear program.

In exchange, the U.S. would lift its ⁠blockade on Iranian ports and issue some sanctions waivers on Iranian oil, Axios said, citing a U.S. official.

The draft agreement also includes commitments from Iran never to pursue nuclear weapons and to negotiate over ​a suspension of its uranium enrichment program and the removal of its stockpile of highly enriched uranium, the Axios report said.

The New York Times reported that the proposed deal includes an “apparent commitment” by Iran to ​give up its highly enriched uranium. Details of how Iran would cede that stockpile would be left for a subsequent round of talks, the newspaper said, citing two unidentified U.S. officials.

Trump, while offering various war aims during the three-month-old conflict, has repeatedly said the U.S. struck Iran to prevent it from obtaining nuclear weapons. Iran has denied it is pursuing nuclear weapons and says it has a right to enrich uranium for civilian purposes.

Iran said on Saturday that it was ​working toward a memorandum of understanding on ending the war after its top officials met with Asim Munir, the army chief of Pakistan, which has sought to be a mediator.

The Pakistani army said the ​negotiations had resulted in “encouraging” progress. Two Pakistani sources involved in the talks said the deal being negotiated is “fairly comprehensive to terminate the war.”

Sources have told Reuters the proposed framework would unfold in three stages: formally ending the war, resolving ‌the crisis ⁠in the Strait of Hormuz and launching a 30-day window for negotiations on a broader agreement, which can be extended.

One of the Pakistani sources said that if the U.S. accepts the memorandum, further talks could take place after the Eid holiday ends on Friday.

Trump, whose approval ratings have been hit by the war’s impact on U.S. energy prices, said on Friday he would not attend his son’s wedding this weekend, citing Iran among the reasons he planned to stay in Washington.

‘ISSUES STILL NEED TO BE DISCUSSED,’ IRAN SAYS

Trump spoke on Saturday with leaders from Saudi Arabia, Qatar, the United Arab Emirates, Jordan, Egypt, Turkey and Pakistan. The leaders ​encouraged Trump to agree to the emerging framework, ​Axios reported.

A call with Israeli Prime Minister Benjamin ⁠Netanyahu also went “very well,” Trump wrote on Truth Social.

Pakistan has aimed to narrow differences between Iran and the U.S. after weeks of war have left the vital Hormuz waterway closed to most shipping despite a nervous ceasefire.

“The trend this week has been towards a reduction in disputes, but there are still issues that ​need to be discussed through mediators. We will have to wait and see where the situation ends in the next three or four days,” ​said Iranian Foreign Ministry spokesperson ⁠Esmail Baghaei.

Iran has demanded supervision of the strait, an end to the U.S. blockade on its ports and the lifting of sanctions on Iranian oil sales.

Baghaei said the issue of the U.S. blockade on Iran’s shipping was important, but that its priority was ending the threat of new U.S. attacks and the ongoing conflict in Lebanon, where Iran-allied Hezbollah militants are fighting Israeli troops who have moved into the south.

Pakistan’s army chief Munir left ⁠Tehran on Saturday ​after talks with Iran’s top negotiator Mohammad Baqer Qalibaf and Foreign Minister Abbas Araqchi.

Qalibaf said Iran’s armed forces had rebuilt ​their capabilities during the ceasefire and that, if the U.S. “foolishly restarts the war,” the consequences would be “more forceful and bitter” than at the start of the conflict.

Despite weeks of conflict, Iran has preserved its stockpile of near-weapons-grade enriched uranium as well as missile, ​drone and proxy capabilities.
