US and Iranian officials have made "significant progress" in high-stakes nuclear talks in Geneva, the Omani foreign minister has said, but the chances of a deal that could avert a war remain unclear, BBC reported. 

Badr Albusaidi, who acted as mediator, said the two sides planned to resume negotiations "soon" after consultations in their capitals, and technical-level discussions would take place next week in Vienna.

Iran's Foreign Minister Abbas Araghchi, who led his country's delegation, said "good progress" had been made and while there had been agreement on some issues, differences remained on others, according to BBC.
