Iranian authorities have accused the US of ‌violating ⁠the ⁠ceasefire agreement between the two sides by firing at one of ​Iran’s commercial ships in ​the Gulf of ​Oman.

Iran’s top joint military command, the Hazrat Khatam al-Anbiya Central Headquarters, vowed to respond swiftly to the US actions.

“We warn that the ⁠armed ​forces of ​the Islamic Republic ​of Iran will ‌soon respond and retaliate against ​this ⁠armed piracy by the US military,” ⁠the ​spokesperson said.

Earlier, US naval forces stationed in the region intercepted and seized an Iranian-flagged cargo vessel, which they said had tried to sail through the waters of the Gulf of Oman, in violation of the US blockade of Iranian ports and shipping.

Iranian state media quoted a military ‌spokesperson as saying that the vessel was en route from ​China to Iran.

Hours after Donald Trump announced he was dispatching US negotiators for a fresh round of talks in Islamabad, Iran said it has no intention of joining.

So far, engagement between Washington and Tehran has been limited to a single 21-hour negotiating session in Islamabad on April 11 that ended without any breakthrough.

Iranian parliament speaker Mohammad Bagher Ghalibaf said afterwards that the US side “ultimately failed to gain the trust of the Iranian delegation in this round of negotiation.”

Washington’s hardline stance further complicates matters

A major sticking point is the US blockade of Iranian ports, which continues to overshadow diplomacy just days before the two-week ceasefire is due to expire.

Trump’s announcement that US Marines had seized an Iranian ship attempting to evade the blockade is likely to fuel tensions further.

Although Iran briefly reopened the Strait of Hormuz following a ceasefire in Lebanon, it quickly reversed course in response to the ongoing US blockade.

Earlier, the Fars and Tasnim news agencies, citing anonymous sources, reported that lifting the US blockade was a precondition for any renewed talks.

Another point of contention: Iran’s enrichment program

Trump said on Friday that Iran had agreed to give up its stock of around 440 kilograms of enriched uranium. 

However, Iran’s Foreign Ministry later said the stockpile was “not going to be transferred anywhere.”

Foreign Ministry Spokesman Esmaeil Baghaei told state TV that the “transfer of Iran’s enriched uranium to the US has never been raised in negotiations.”

Tehran was not planning to take part in a new round of negotiations with the United States in Islamabad, Iranian state media reported on Sunday

“There are currently no plans to participate in the next round of Iran-US talks,” state broadcaster IRIB reported, in English, on X.

It was not immediately clear who was behind the announcement.

President Donald Trump said US forces seized an Iranian-flagged cargo ship on Sunday. The vessel was trying to evade a US naval blockade near the Strait of Hormuz, he wrote in a post on his Truth Social platform.

“Our Navy ship stopped them right in their tracks by blowing a hole in the engineroom,” Trump wrote.

He added that US Marines had taken custody of the ship, named Touska, and were “seeing what’s on board!”

Pakistani Prime Minister Shehbaz Sharif said he discussed the conflict in the Gulf with Iranian President ⁠Masoud Pezeshkian on Sunday.

Sharif wrote in a post on X that he “shared insights from my recent engagements with leaders of Saudi Arabia, Qatar and Türkiye.”

“I appreciated Iran’s engagement, including its high-level delegation to Islamabad for the historic talks, ⁠and recent discussions with Field Marshal Syed Asim Munir,” Sharif said.

Sharif told Pezeshkian that Pakistan remains ⁠committed to its role as a ⁠facilitator of peace and regional stability.

It is still unclear whether Iran will ultimately join the second round of talks in Islamabad with the United States.

State-run Iranian news agency Irna reported Sunday that “there is no clear prospect of fruitful negotiations.”

Irna also pointed to Washington’s “maximalism and unreasonable and unrealistic demands, frequent changes of positions, constant contradictions and the continuation of the so-called naval blockade.”

Meanwhile, the Fars and Tasnim news agencies, quoting anonymous sources, said, “The overall atmosphere cannot be assessed as very positive.” 

Fars cited one source as saying that the lifting of a US blockade on Iranian ports was a precondition for continued talks.

On Friday, German Chancellor Friedrich Merz said his country was prepared to supply mine clearance and maritime reconnaissance to help secure the Strait of Hormuz.

The same day, Iran’s top diplomat Abbas Araghchi declared the critical waterway “completely open” for the duration of the Israel-Lebanon ceasefire, and US President Donald Trump likewise said it was “ready for full passage.”

The following day, Iran reversed its decision, shutting the strait again.

Either way, maritime traffic might still be at risk, given that Iranian authorities had previously indicated there may be underwater mines in the strait.

How dangerous are naval mines, and what can be done to clear them? Find out here.

US Vice President JD Vance, who led the first round of talks between the US and Iran last weekend, will return to Islamabad for the negotiations, according to a White House official.

Trump’s envoy Steve Witkoff and son-in-law Jared Kushner will also be part of the delegation.

Earlier, Trump had said Vance would not go to the Pakistani capital. “It’s only because of security,” Trump told ABC News. “JD’s great.”

Last Sunday, Vance left Islamabad after 21 hours of talks with Iranian officials ended without a breakthrough. 

Germany-based TUI Cruises said ‌that ⁠its ⁠Mein Schiff 4 and Mein Schiff ​5 ships passed through the ​Strait of Hormuz on Sunday.

According to the maritime data service MarineTraffic, only one other cruise ship, the Celestial Discovery, formerly known as the Aida aura, had been able to pass the strait since the start of the Iran war on February 28, when the US and Israel attacked Iran.

Tui ​said that all passengers ​had previously been ‌brought home and both ships were ​operating ⁠with reduced crews, adding that it had obtained approvals ‌from ​relevant authorities to cross the strait, under careful consideration of the security situation.

It said ​the ships would now continue on to the Mediterranean ⁠Sea.

French President Emmanuel Macron is expected to meet with Lebanese Prime Minister Nawaf Salam in Paris this week, his office announced.

The meeting comes amid a fragile 10-day ceasefire between Israel and the Iran-backed militant group Hezbollah.

The visit was announced a day after France blamed Hezbollah for an ambush on UN peacekeepers that left one French soldier dead and three others wounded.

Macron is expected to urge Lebanese authorities to “shed full light on the incident” and “identify and prosecute those responsible without delay,” his office added.

With the move, the French government will highlight Macron’s commitment to seeing “full and complete respect for the ceasefire in Lebanon” as well as France’s support for Lebanon’s “territorial integrity,” the president’s office said on Sunday.

Iran is not sending a ​negotiating ​delegation ‌to Pakistan “as long ‌as there is ‌a ​naval blockade,” Iran’s Tasnim ​news agency ⁠reported on ​Sunday.

The development came after Pakistani Foreign Minister Ishaq Dar, who spoke by phone with his Iranian counterpart Abbas Araghchi on Sunday, had said his country was working to “bridge” differences between Washington and Tehran.

Earlier, US President Donald Trump had announced that US negotiators were due in Islamabad on Monday evening.

Late Saturday, Parliament Speaker Mohammed Bagher Ghalibaf, who has emerged as Iran’s main negotiator, said in an interview on state television that “there will be no retreat in the field of diplomacy.”

US President Donald Trump accused the Iranian regime of violating the current ceasefire agreement and threatened to “to knock out every single Power Plant, and every single Bridge,” if Iran does not make a deal with the US.

Tehran said on Saturday it would keep the Strait of Hormuz closed. ​At least two ships ⁠reported they had been fired upon while approaching the strait on Saturday. 

“Iran decided to ⁠fire bullets yesterday ​in the Strait of Hormuz — A Total Violation of our Ceasefire Agreement!” Trump wrote in a post Sunday on his Truth Social platform. “That wasn’t nice, was it?”

Iran has called the US blockade on its ports a “violation” of the ceasefire agreement mediated by Pakistan some 10-days ago, which paused over six weeks of fighting.

“The United States’ so-called ‘blockade’ of Iran’s ports or coastline is not only a violation of Pakistani-mediated ceasefire but also both unlawful and criminal,” Iranian Foreign Ministry spokesman Ismaeil Baqaei said Sunday on X.

He cited a United Nations General Assembly resolution to argue that the blockade was an “act of aggression” against Iran.

“Moreover, by deliberately inflicting collective punishment on the Iranian population, it amounts to war crime and crime against humanity,” the Foreign Ministry spokesman went on to say.

Iran has reverted to shuttering the critical Strait of Hormuz after Trump refused to lift the blockade.

US negotiators are due in the Pakistani capital on Monday evening, US President Donald Trump announced on Sunday, as Islamabad mediates efforts aimed at ending the US-Israeli war on Iran.

“My Representatives are going to Islamabad, Pakistan — They will be there tomorrow evening, for Negotiations,” Trump said in a lengthy post on his Truth Social platform.

He then strayed into criticism and threats against Iran, which he accused of violating the ceasefire agreement by attacking ships attempting to pass through the strategic Strait of Hormuz on Saturday.

Iran had briefly reopened the critical waterway on Friday, only to announce closing it again less than 24 hours later after Trump refused to lift a blockade on its ports.

Questioning Iran’s closure of the strait, Trump called it “strange” because “our BLOCKADE has already closed it.”

Without mentioning any of the terms, he also said the US proposed a peace agreement.

“We’re offering a very fair and reasonable DEAL, and I hope they take it because, if they don’t, the United States is going to knock out every single Power Plant, and every single Bridge, in Iran. NO MORE MR. NICE GUY!” Trump went on to say.

Crude prices jumped and the US dollar rose but equity futures fell in early Asian trading on Monday.

The price of Brent crude, the international benchmark, soared as much as 7% to $96.85 a barrel.

The S&P 500 futures, meanwhile, fell about 0.9%, while the US dollar appreciated against several other currencies, including the euro and the Japanese yen.

The market movements signal investor concern over the Middle East situation, with Iran shutting the Strait of Hormuz once again amid the continuing US blockade of Iranian ports and ships.
