Hopes grew on Friday for peace between Iran and the United States after President Donald Trump said a deal could be signed as ​soon as this weekend, even as Tehran said it had not made a final decision on a pact.

The deal, if confirmed, would ‌be the most significant diplomatic breakthrough yet to end the three-month-old war, which has killed thousands and sent global energy prices sharply higher after Iran all but closed the Strait of Hormuz to shipping.

“We just made a great settlement of the war with Iran,” Trump told reporters at the White House on Thursday.

“The strait will officially open as soon as we sign, which could be ​soon, very soon, maybe over the weekend in Europe,” he said, adding that Vice President JD Vance would attend the deal signing.

Asked if Iran’s ​Supreme Leader Ayatollah Mojtaba Khamenei had approved the deal, Trump said, “I understand the answer is yes.”

Since mid-March, Trump has repeatedly claimed ⁠a deal with Iran to end the war was close. The two sides have traded strikes this week, straining a ceasefire announced in April.

Iranian media reported Foreign ​Ministry spokesperson Esmaeil Baghaei as saying large parts of the agreement have been finalised, but Iran would not compromise on its red lines.

“We have not reached a ​conclusion on this matter,” he said. “This is a very important issue that is currently being reviewed by the relevant decision-making bodies.”

Markets rally despite tension

Asian stocks joined a strong global rally on Friday on hopes that a peace deal may finally materialise, while oil prices fell to two-month lows.

Still, tension remained high around the Strait of Hormuz, with US forces shooting down two Iranian ​one-way attack drones after Tehran attempted to strike commercial ships transiting the vital waterway, a US official said.

Iran’s military stopped a tanker from transiting the strait, state ​media said, reporting the sound of explosions early on Friday.

Trump’s announcement came after he called off planned military strikes on Iran, citing progress in talks.

“It’s a very strong memorandum of ‌understanding that ⁠is a little conceptual,” Trump told reporters.

Trump has repeatedly said any peace deal must ensure Iran cannot develop a nuclear weapon. Iran denies it is seeking such a weapon.

Iran’s demands include the lifting of international sanctions, the release of billions of dollars in frozen assets and recognition of its control of the Strait of Hormuz.

“The big thing is there will be no nuclear weapons in Iran. That means not developed and not purchased,” Trump later said during a campaign event held by telephone.

Tit-for-tat strikes

The war has killed thousands of people, mainly in Iran and Lebanon, and ​hit the world economy by pushing up energy prices since the US and Israel launched airstrikes on Iran on February 28.

In recent days, the conflict has intensified despite a tenuous ceasefire that took effect in early ‌April.

After ⁠a US Apache helicopter was downed, Trump this week ordered new strikes around the Strait of Hormuz over two days.

At the same time, Iran launched missile and drone attacks on US bases in the region.

Bahrain’s interior ministry said on Thursday an 11-year-old girl suffered minor injuries and homes were damaged after debris fell from Iranian drones that were intercepted and destroyed.

Trump had said earlier Thursday that the United States would hit Iran “very hard tonight” and wanted eventually to take Iran’s oil infrastructure hub, Kharg Island.

The island handles 90% of Iran’s oil exports, and seizing it would give the United ​States the ability to severely disrupt Iran’s energy ​trade, placing enormous pressure on Tehran’s economy.

Iranian ⁠state media said early on Friday that the country’s forces prevented a tanker from transiting the Strait of Hormuz without coordination.

One-fifth of the world’s energy shipments normally travel through the narrow waterway, but it has been largely shut since the war began.

Domestic pressures

The conflict has become a political headache ​for the White House, with polls showing Trump’s approval ratings sinking amid voter anger over high gasoline prices.

Some Republicans have openly worried that ​the war’s unpopularity could cost ⁠them control of Congress in November’s midterm elections.

But Trump’s political considerations also include satisfying Iran hawks within his Republican Party, who scuttled a prior effort, that any agreement closes Tehran’s path to developing a nuclear weapon.

The reaction of other Middle East powers will also be crucial.

Trump said on social media that the agreement had been approved by countries including Israel, Saudi Arabia, Qatar and the United Arab Emirates.

Prime Minister Benjamin Netanyahu’s ⁠office said in ​a statement after the Israeli leader and Trump spoke that Israel was not a party to the memorandum of ​understanding with Iran.

Netanyahu expressed his appreciation for Trump’s commitment to securing a deal that includes removing enriched material, dismantling enrichment infrastructure, limiting missile output and ending support for regional proxies, according to the readout.

Tehran has been demanding an end to Israeli ​attacks in Lebanon, where fighting has continued in a parallel war between Israel and Iran-backed Hezbollah militants.
