The US and Iran have agreed to hold nuclear talks in Oman on Friday, as President Donald Trump issued a blunt warning to Supreme Leader Ayatollah Ali Khamenei.


Iranian Foreign Minister Abbas Araghchi said that the meeting would start at 10:00 (06:00 GMT) in Muscat. US officials also confirmed that the talks would take place there.


The discussions had appeared at risk due to disagreements between the two nations regarding the location and specifics involved.


Trump has bolstered US military presence in the region and warned of potential military action if Iran fails to negotiate a deal concerning its nuclear program and ceases violence against protesters. When asked if Khamenei should be concerned, he stated: 'I would say he should be very worried.'


Khamenei, in response, has cautioned that any US assault on Iran could precipitate a 'regional war.'


As negotiations loom, an Arab diplomat disclosed to the BBC's partner CBS News that discussions had never been formally canceled, although momentum had fluctuated. Reports indicated the US administration received pressure from several Arab and Muslim leaders against withdrawing from negotiations.


Moreover, US Secretary of State Marco Rubio emphasized that any meaningful talks should encompass a range of issues beyond the Iranian nuclear program, including ballistic missile capabilities and Iran's involvement with regional militant groups.


In light of these ongoing tensions, both nations are exploring the possibilities of dialogue, with Iranian officials asserting a commitment to a peaceful nuclear agenda.
