US Defense Secretary Pete Hegseth has said the next few days in the war against Iran would be decisive and warned Tehran that the conflict would intensify if it did not make a deal.
Mr Hegseth issued his warning hours after Iran set ablaze a fully loaded oil tanker off Dubai, its latest attack on merchant vessels in the Gulf or in the Strait of Hormuz since the United States and Israel attacked Iran on 28 February.
US President Donald Trump yesterday threatened to obliterate Iran's energy plants if it does not agree to a peace deal and open the strait, a vital waterway for global oil shipments that has effectively been blocked by Iran.
Mr Trump has criticised countries that have not helped in the war, including France and Britain, saying they should find "some delayed courage" to take the strait and get their own oil. Sources told Reuters France had not allowed its airspace to be used to transport US weapons for use in the war.
Mr Hegseth, who said he visited US troops in the Middle Easton on Saturday, said Mr Trump was willing to make a deal and talks were ongoing and gaining strength, but that the US was prepared to continue the war if Iran did not comply.
"We have more and more options, and they have less ... in only one month we set the terms, the upcoming days will be decisive," Mr Hegseth said in Washington. "Iran knows that, and there's almost nothing they can militarily do about it."
Oil prices head for record monthly gain
The month-old conflict has spread across the region, killing thousands, disrupting energy supplies and threatening to send the global economy into a tailspin.
Crude oil prices briefly spiked again after the attack on the tanker, which can carry around 2 million barrels of oil worth more than $200 million at current prices.
Authorities in Dubai said the fire on the Kuwait-flagged Al-Salmi had been brought under control following a drone attack, with no oil leak and no injuries to the crew. Kuwait Petroleum Corp, the ship's owner, said the vessel's hull was damaged, and photos of the Al-Salmi confirmed this.
LSEG Data showed the vessel was heading to Qingdao in China, and was carrying 1.2 million barrels of Saudi crude oil and 800,000 barrels of Kuwaiti crude, according to monitoring service TankerTrackers.com.
The Al-Salmi may not have been the intended target. Iran's Revolutionary Guards said they had targeted a container ship in the Gulf over its ties with Israel. But they appeared to be referring to the Singapore-flagged Haiphong Express, which was anchored next to the Al-Salmi, according to shipping data.
US General Dan Caine, chairman of the Joint Chiefs of Staff, told reporters in Washington that the US was continuing to degrade and destroy Iran's capabilities.
He said the US military was continuing to strike key manufacturing and research sites and had taken out over 150 Iranian naval vessels. Mr Hegseth said US strikes were causing widespread desertions in Iran.
Thousands of soldiers from the US Army's elite 82nd Airborne Division have started arriving in the Middle East, two US officials told Reuters yesterday, reinforcements that could expand Mr Trump's options to include a ground assault in Iran.
With attacks showing no sign of easing, Pakistan is seeking to mediate in the war. Its foreign minister, Ishaq Dar, is due to discuss the conflict during a visit to China after hosting talks with Turkey, Egypt and Saudi Arabia.
Iran has remained defiant despite heavy US and Israeli attacks for the past month. It has received US peace proposals via intermediaries, but its foreign ministry spokesperson said yesterday they were "unrealistic, illogical and excessive".
The failure to secure a peace deal has prompted the European Union's energy chief to warn member states to prepare for a"prolonged disruption" to energy markets. Higher oil and fuel prices have also started to weigh on US household finances and are a political headache for Mr Trump and his Republican Party before November midterm elections.
The US national average retail price of gasoline crossed $4 agallon for the first time in over three years yesterday, data from price-tracking service Gas Buddy showed. Tight global supplies have pushed benchmark Brent crude up to above $114 per barrel, putting them on course for a record monthly gain.
New attacks
The war has continued to spread, with Iran-aligned Houthis in Yemen entering the war by firing at Israel, and Turkey reporting yesterday that a ballistic missile launched from Iran had entered Turkish airspace before being shot down.
The war has also revived conflict between Israel and the Iran-backed Lebanese group Hezbollah, while Iran, which has the highest casualty toll in the war, has fired at targets in Gulf Arab states, where the US has military bases.
A strike on a Shi'ite Muslim congregation hall in the northwestern Iranian city of Zanjan killed three people, a provincial official told Iranian media.
The Israeli military said it carried out overnight airstrikes in Tehran targeting a ballistic missile warhead factory, weapons research sites and missile launch systems, under intelligence guidance.
It said four of its soldiers had been killed in southern Lebanon, where three United Nations peacekeepers from Indonesia have been killed in two separate incidents.
