Iran said it has reached an understanding with the United States on key guiding principles aimed at resolving the long-running dispute over Tehran’s nuclear programme following indirect talks in Geneva.

Iranian Foreign Minister Abbas Araghchi said some work still remains, while Washington acknowledged that progress was made during the discussions.

Oman, which is mediating the talks, said the negotiations ended with good progress toward identifying shared goals and technical issues. Omani Foreign Minister Badr Albusaidi described the outcome as constructive.

The meeting came amid heightened tensions, including repeated US military warnings over Iran’s nuclear activities and its crackdown on protests. US President Donald Trump earlier said he believed Tehran was interested in reaching a deal.

The US and its European allies have long accused Iran of seeking to develop nuclear weapons, a claim Tehran has consistently denied. Iran has said the talks focus on its nuclear programme and the possible lifting of US economic sanctions, while Washington has indicated interest in discussing other issues, including Iran’s missile programme.

A US official said the sides would continue discussions, with Iran expected to return with detailed proposals in the coming weeks to narrow remaining gaps. US Vice President JD Vance said some US red lines were yet to be addressed.

Trump, speaking earlier, said Iran wanted to avoid the consequences of failing to reach an agreement, referring to past US military action against Iranian nuclear sites.

Iran has meanwhile warned against threats, with Supreme Leader Ayatollah Ali Khamenei saying attempts to predetermine the outcome of negotiations would be wrong.

The latest round followed earlier indirect talks held in Oman, which both sides had described as a positive start.
