Iranian Foreign Minister, Hossein Amir-Abdollahian, stressed his country's refusal to tie the affair of prisoner exchange with the nuclear talks, as Iran sees the former from a humanitarian perspective.

Amir-Abdollahian also highlighted his country's support for negotiations that can lead to tangible, positive results that all sides can abide by, thereby leading to Iran's return to its commitments.

Guterres, on his part, hoped that the nuclear talks would prove successful, declaring the UN's continued support for the nuclear deal, and its search for a way to bring things back to the way they were before the Trump administration exited the deal.

Washington: We will continue to impose sanctions on Iran

The US said it was necessary to hold talks in Brussels with Iran before talks on reviving the nuclear talks can be resumed.

US State Department Spokesperson Ned Price said that his country will continue to impose sanctions on Tehran until it abides by the deal again.

Iran's Foreign Ministry Spokesperson Saeed Khatibzadeh had said, during the weekly press conference, that Iran has not set any conditions for the US in the nuclear talks because it is not a member of the JCPOA, stressing the need to specify the problems of the prior six rounds of the Vienna talks; otherwise, the talks will continue for several rounds.

The powers that are still party to the agreement began talks in Vienna this year, along with indirect US participation, after US President Joe Biden expressed his will to bring his country back to the deal. Six rounds of talks were conducted between April and June.
