Rafael Grossi has warned that time is running out to secure a nuclear agreement between Iran and the United States, even as he described a “step forward” in Omani-mediated talks in Geneva. Grossi, who leads the International Atomic Energy Agency, said dialogue is beginning to take shape but remains highly complex.
Speaking to French television, Grossi said negotiators are finally discussing concrete issues. However, he stressed that progress remains fragile as Tehran continues to limit cooperation with the UN watchdog. Iran has restricted inspector access to sites targeted during Israeli and US strikes linked to last year’s brief conflict.
US military buildup raises pressure on Tehran
Meanwhile, Washington has significantly reinforced its military presence in the Middle East, signalling readiness for possible action if ordered by President Donald Trump. Reports indicate a large deployment of warships, including an aircraft carrier group, alongside additional forces en route to the region.
The White House has maintained strong pressure on Tehran. Press Secretary Karoline Leavitt said Iran would be “very wise” to reach an agreement, noting modest progress but warning that arguments for military action remain.
Open-source intelligence has also tracked increased US air operations, including stealth fighters and refuelling aircraft supporting sustained readiness. Trump initially ordered the surge after Iran’s crackdown on protests earlier this year.
Although he briefly stepped back from potential strikes after Iran paused executions, the US president has renewed calls for a replacement to the 2018 nuclear deal, keeping tensions elevated as negotiations continue.
