Tehran indicates it will not accept the US proposal made during the fifth round of talks last month.

Iran will soon present a counterproposal for a nuclear deal to the United States, according to its Ministry of Foreign Affairs.

Esmaeil Baghaei, the ministry’s spokesman, told a weekly news conference on Monday that Iran was not satisfied with a US proposal and it would present its version via mediator Oman.

This marks the first public sign that Tehran will not accept the US proposal after the fifth round of talks last month, during which Iran said it had received “elements” of a US proposal and Foreign Minister Abbas Araghchi later said the text contained “ambiguities”.

Baqhaei criticised the US proposal on Monday as “lacking elements” reflective of the previous rounds of negotiations, but he did not provide details.
