Iran has ruled out the resumption of nuclear talks with the United States, signalling a shift in diplomatic strategy after US and Israeli airstrikes inflicted “excessive and serious” damage on its nuclear infrastructure.

Foreign Minister Abbas Araghchi said on Thursday there were currently no plans to return to negotiations with Washington, confirming that a scheduled sixth round of talks was scrapped after Israel began its military campaign earlier this month.

“I would like to state clearly that no agreement, arrangement or conversation has been made to start new negotiations,” Araghchi told state media.

He added that the Iranian government was reassessing its diplomatic posture: “We are examining what is in the interest of the Iranian people,” he said, noting that Tehran’s diplomatic approach would take a “new form”, though he did not elaborate.

The remarks come amid growing internal and external tensions following joint US-Israeli airstrikes on Iran’s nuclear sites at Fordo, Natanz and Isfahan. While Iran’s Supreme Leader Ayatollah Ali Khamenei insisted the strikes had “failed to accomplish anything significant” and accused US President Donald Trump of exaggerating the outcome, Araghchi offered a more candid assessment.

He admitted that Iran’s nuclear facilities had suffered “excessive and serious” damage, adding that the Atomic Energy Organisation of Iran was still carrying out assessments.

The foreign minister’s comments appeared to directly contradict Khamenei, who earlier claimed victory over the US and Israel and dismissed the attacks as ineffective.

The US entered the conflict last weekend with targeted strikes on Iranian nuclear sites, prompting Trump to later broker a temporary ceasefire between Tehran and Tel Aviv. US Defence Secretary Pete Hegseth said the bombings had “significantly damaged” Iran’s nuclear programme and set it back by years. However, a leaked Pentagon report reportedly suggested the strikes only delayed the programme by a few months—a claim dismissed by the administration.

Iran, which maintains that its nuclear programme is entirely peaceful, is also moving to reduce its international commitments. On Wednesday, Iran’s parliament passed a bill to suspend cooperation with the International Atomic Energy Agency (IAEA), citing the body’s refusal to condemn the strikes. If enacted, the law would halt inspections and surveillance at Iranian nuclear sites.

Iran’s health ministry says 610 people were killed in the 12-day bombardment by Israel. Israeli officials, meanwhile, report 28 deaths from Iranian strikes.
