President Donald Trump has suspended attacks on Iran for the second night in a row to give more time for diplomacy, the US ambassador to the UN said.

Speaking to Fox News on Sunday, Ambassador Mike Waltz said the president was “giving the talks some space, he’s giving them some space.”

An Iranian military spokesman said on Sunday that Tehran had stopped “retaliatory” attacks in the region in response.

The pause comes after nearly two weeks of daily U.S. strikes and tit-for-tat attacks, which effectively unraveled the ceasefire reached in June.

Asked if Trump had decided not to escalate the situation for now, Waltz told NBC: “I wouldn’t go that far at all. The president keeps all options on the table.”

Waltz also rejected reports from the New York Times., external that administration officials had warned that expanding hostilities could dangerously deplete a diminished stockpile of air defense munitions.

“The U.S. military…has everything it needs to conduct this campaign as effectively as it needs to,” he said.

Meanwhile, Iran and Oman held several rounds of technical talks in Tehran on Friday and Saturday to discuss the management of the Strait of Hormuz, according to Iranian Foreign Ministry spokesman Esmail Baghaei.

Disputes over control of the strait reignited tensions between the United States and Iran earlier this month and remain a major obstacle to permanently ending the war.

Iran and the US signed a memorandum of understanding in June to stop military operations and reopen the strait, as well as reach an agreement to end the war within the next 60 days.

But after Iranian forces attacked oil tankers in the Strait of Hormuz on July 13, the United States resumed airstrikes against the country and reestablished its naval blockade of Iranian ports.

Iran retaliated with attacks on US military facilities and bases across the Middle East, killing four US soldiers. Since then, US strikes have killed dozens of people, according to Iran’s Health Ministry.

In the UK, new Defense Secretary Wes Streeting said he would meet his US counterpart Pete Hegseth next week to discuss the strait, which is one of the world’s key shipping routes for oil, liquefied natural gas and other essential raw materials.

“When it comes to ensuring maritime freedom and free commercial navigation in the Strait of Hormuz, that is where we are absolutely aligned,” Streeting told the BBC.

Earlier this week, oil prices hit $100 a barrel for the first time since May, as renewed fighting stoked fears about global energy supplies.

As the war approaches its fifth month, it remains largely unpopular in the United States, and a new CBS/YouGov poll suggests that 57% of Americans are frustrated by the conflict and only 19% are optimistic.

Thousands of people have been killed across the Middle East since the US-Israel war against Iran began in February, official figures show, with the vast majority coming from Iran and Lebanon.

President Trump will meet with Israeli Prime Minister Benjamin Netanyahu at the White House on Tuesday.
