TEHRAN/NEW YORK – Negotiations between delegations from Iran and the United States will be extended for another day at Pakistan’s proposal and at the two sides’ consent, the semi-official Tasnim news agency reported early Sunday.

The report said given the “illogical and excessive demands” of the United States and the Iranian delegation’s insistence on ensuring national interests, Pakistan proposed to hold another round of negotiations on Sunday and the two sides agreed.

This occurred at the end of the latest round of Pakistani-mediated talks that ended early Sunday in Islamabad, and after the two delegations exchanged texts, according to Tasnim.

The negotiations started at 1 pm local time (0800 GMT) on Saturday and continued for more than 14 hours, the report said.

Tasnim said earlier that certain serious differences still remain between the two sides, adding that “the ball is now in the US court to put aside its usual excessive demands and replace its ambitious approach with a realistic one.”

It quoted an informed source as saying that despite the initial progress achieved in the negotiations between the two sides’ expert teams, the delegations still have “serious” differences over the Strait of Hormuz and a number of other issues, and no tangible change has occurred in the talks due to the US “excessive demands.”

The report stressed that some Western media are exaggerating the talks’ “positive atmosphere” to control global energy prices.

Regarding the latest round, Tasnim said: “Given the US excessive demands, this round appears to be the last chance given by the Iranian team to the Americans to achieve a joint framework.”

Delegations from Iran and the United States are in Islamabad for talks aimed at easing tensions in the Middle East following a ceasefire reached earlier this week after more than a month of fighting.

Trump unbothered

US President Donald Trump said Saturday he is not bothered about the outcome of the US-Iran talks in Pakistan.

Trump insisted that the United States had come out ahead from the war. “Whether we make a deal or not makes no difference to me. The reason is because we’ve won,” Trump told reporters when departing the White House.

“We’re in very deep negotiations with Iran. So we win regardless,” Trump said.

“We’ve defeated them militarily. We’ve defeated their military. They have no navy. 158 ships are underwater. Undersea. All of their minesweepers,” he claimed.

Iran rejects claim 2 US warships transited Hormuz Strait

Meanwhile, Iran’s Khatam al-Anbiya Central Headquarters “strongly” denied Saturday that US vessels had approached or entered the Strait of Hormuz, rejecting a US claim that two warships had transited the waterway.

According to the semi-official Fars news agency, Ebrahim Zolfaghari, spokesman of the headquarters commanding all Iranian armed forces, said that the claim by US Central Command (CENTCOM) commander Brad Cooper about “the approach and entry of US vessels to the Strait of Hormuz is strongly denied,” and “authority over any vessel’s passage lies with the Armed Forces of the Islamic Republic of Iran.”

Earlier on Saturday, CENTCOM said that two US Navy guided-missile destroyers — USS Frank E. Peterson and USS Michael Murphy — transited the waterway and began mine-clearing operations in the Gulf.

In a post on social media platform X, CENTCOM said that the operation was “part of a broader mission to ensure the strait is fully clear of sea mines.”

“Today, we began the process of establishing a new passage and we will share this safe pathway with the maritime industry soon to encourage the free flow of commerce,” said Cooper.

Iranian military analyst Nima Akbarkhani told the semi-official Mehr news agency that even the world’s most advanced warship could not pass through the Strait of Hormuz undetected.

Akbarkhani added that the US warship attempted a “high-risk operation” on Saturday using electronic warfare and identity disguise, but Iran’s naval forces exercised restraint amid a recent ceasefire and issued a serious warning.

The developments come as delegations from Iran and the United States are currently in Islamabad for talks on easing tensions in the Middle East after a ceasefire was achieved between the two countries early Wednesday.

On Feb 28, Israel and the United States launched joint attacks on Tehran and several other Iranian cities, killing Iran’s then Supreme Leader Ali Khamenei, along with senior military commanders and civilians. Iran responded with waves of missile and drone strikes targeting Israel and US assets in the Middle East, and tightened control over the Strait of Hormuz by restricting passage by vessels belonging to or affiliated with Israel and the United States.
