Third round of Iran-US talks took place in the Oman's ambassador residence in Cologny, Geneva.
The US delegation was seen leaving the residence soon after noon.
Earlier on Thursday, US envoys Jared Kushner and Steve Witkoff met with the Foreign Minister of Oman Badr bin Hamad Al Busaidi as part of the ongoing Iranian-American negotiations.
During the meeting, they reviewed Iran's proposals and the responses and inquiries of the US negotiating team related to Iran's nuclear program and the guarantees necessary to achieve an agreement and its technical and regulatory aspects, the Omani Foreign Ministry wrote in a statement accompanying the photos on X.
Oman's FM explained "that efforts are continuing diligently and in a constructive spirit, with negotiators open to new and creative ideas and solutions in an unprecedented manner, and conditions conducive to progress and reaching a fair agreement with sustainable guarantees are being created," the statement says.
Foreign Minister Abbas Araghchi is leading Iran's negotiating team on Thursday.
US announced fresh sanctions targeting Iran on Wednesday as Vice President JD Vance warned Tehran to take threats of military action "seriously". Iranian President Masoud Pezeshkian said that he had a "favorable outlook for the negotiations".
