US-Iran truce deal awaits Trump as strikes test ceasefire

US and Iranian negotiators edged toward a deal to extend their fragile ceasefire for 60 days, but the potential breakthrough was still hanging on President Donald Trump's approval, US sources told the media on Thursday.
The development came after Washington and Tehran accused each other of violating the truce, underscoring the volatility of talks three months after the Middle East war began with US-Israeli strikes on Iran.
The US sources confirmed reporting by Axios that the two sides had agreed on a memorandum of understanding to prolong the ceasefire and launch negotiations on Iran's nuclear programme.
Under the proposed deal, shipping through Hormuz would be unrestricted, with no tolls or harassment; Iran would remove all mines within 30 days; and the United States would lift its naval blockade if commercial traffic resumes, Axios reported.
But Iran's Tasnim news agency, citing a source close to Tehran's negotiators, said the text had not been finalised and that Pakistan would be informed if a deal was reached.
Iranian sources cited by local media said any deal would be complete only when announced by Tehran, not unilaterally by Trump.
Late on Thursday, US Vice President JD Vance told reporters that Trump was not yet ready to approve it, even though negotiations had "made a lot of progress."
"We're going back and forth on a couple of language points," he added.
US strikes on the southern Iranian port city of Bandar Abbas prompted Iran to target "the American airbase that served as the source of the attack," state broadcaster IRIB reported, citing the Revolutionary Guards.
The Guards did not specify the location of the base, but Kuwait, which hosts US troops, said its air defences responded to incoming fire.
Kuwait's foreign ministry condemned "the criminal Iranian attacks that targeted the territory of the State of Kuwait with missiles and drones, in a dangerous escalation."
US Central Command called the attack an "egregious ceasefire violation."
Iranian forces had fired at four ships trying to transit the Strait of Hormuz without authorisation, IRIB reported Thursday. Iran has blockaded the waterway since the war began.
US forces said they had intercepted five attack drones in and around the strait, and prevented the launch of a sixth near Bandar Abbas.
Iranian foreign ministry spokesman Esmaeil Baqaei called the US strikes truce "violations".
A US official told the media the actions were "measured" and "intended to preserve the ceasefire".
Iran's Guards threatened a "firm response" to any renewed attacks.
Strait standoff
Before Thursday's strikes, Amir, a 27-year-old software developer in Tehran, said fears of renewed fighting were constant.
"I feel like nothing is certain yet," he said. "The daily question is: Will there be missile strikes tonight?"
A key focus of the proposed deal is restoring full traffic through the Strait of Hormuz, the closure of which has curbed the vast flows of oil and gas that normally pass through it.
Oil prices bounced higher Thursday after reports of the strikes, reversing much of Wednesday's deal-driven fall.
Markets remained choppy as traders balanced hopes of a ceasefire extension against the risk of renewed fighting. Brent crude slipped after earlier jumping around 2.5 percent, while Wall Street closed higher even as European and Asian markets mostly fell.
The war's economic toll has become harder to ignore, with analysts warning that prolonged disruption in Hormuz could keep energy prices high and make inflation harder to contain.
Trump threatened US ally Oman when asked about a possible short-term arrangement allowing it and Iran to control the strait.
"No, the strait is going to be open to everybody," Trump said. "It's international waters and Oman will behave just like everybody else or we'll have to blow them up."
US Treasury Secretary Scott Bessent on Thursday also threatened to "aggressively target" Oman if it helped impose tolls in the strait.
Bessent added Washington would halt Iranian airlines' access to landing slots, refuelling and ticket sales, while allowing travel for religious pilgrimage and humanitarian reasons.
Oman mediated US-Iran talks in Geneva before the war and has itself come under attack from Tehran.
Baqaei called the threat toward Oman "a worrying sign of the normalisation of anarchy and intimidation in international relations".
Qatar's emir also spoke with Trump by phone about efforts to reduce escalation, after Doha hosted senior Iranian officials this week.
