The United States and Iran will meet in Geneva on Thursday for renewed nuclear negotiations, Oman’s foreign minister confirmed on Sunday.
Badr Albusaidi said talks aim to go the extra mile towards finalising a long-stalled nuclear agreement.
Diplomatic contacts resumed earlier this month in Muscat, where indirect discussions restarted after months of silence.
Oman has quietly mediated between Washington and Tehran, serving as a discreet bridge across deep political divides.
Axios reported Washington will attend only if Iran submits a detailed nuclear proposal within two days.
A senior US official said a concrete Iranian plan could unlock detailed negotiations and possibly an interim accord.
Another official confirmed the Geneva meeting but said the administration is still awaiting Tehran’s written proposal.
The official added that US President Donald Trump expects to receive the document by Tuesday.
Iranian Foreign Minister Abbas Araghchi said the proposal is being finalised to accommodate both sides’ concerns.
He told CBS that Iran’s leadership has not yet signed off but expressed confidence in progress.
Senior US officials warned diplomacy may represent the final window before potential military action with Israel.
They cautioned that targets could include Supreme Leader Ali Khamenei, according to Axios.
The warning coincides with a US military buildup across the Middle East.
The aircraft carriers USS Abraham Lincoln and USS Gerald R. Ford are deploying alongside additional fighter jets.
Trump last week set a 10 to 15 day deadline for talks to produce results.
He reiterated that limited strikes remain under consideration if negotiations fail to yield a serious agreement.
