The Iranian and US delegations would be in the same room for the talks slated for Saturday in Oman, Reuters reported citing a US official familiar with the planning.
Iranian officials have insisted that the talks will be indirect, rejecting any direct negotiation with Washington.
A group of hardliners gathered in front of the Iranian Foreign Ministry on Thursday to protest the Islamic Republic's upcoming negotiations with the United States.
The protesters held placards reading, "You'll make a deal again, they'll scrap it again" and "We need guarantees."
Another placard read, "We need a few wise, dignified and honorable officials," referencing Khamenei's earlier stance that negotiations with the US are "unwise, undignified and dishonorable."
Similar protests were held on Wednesday in Tehran's Palestine Square, during which hardline demonstrators torched and trampled on US and Israeli flags.
"Three men in Iran face imminent finger amputations that may be carried out as early as tomorrow (11 April 2025). The prohibition of torture and ill-treatment is absolute and allows no exceptions," Mai Sato, Special Rapporteur on the situation of human rights in the Islamic Republic of Iran, said in a post on X.
UN experts, which include Sato, expressed deep concern over the planned amputations, saying it violates international law and called for the immediate halt of such punishments.
In their statement, the UN experts said the three men were convicted of theft in 2019 and sentenced to amputation, with the Supreme Court upholding the verdict in 2020 despite allegations of torture.
Iran executes five political prisoners
The planned amputations come just days after Iran executed five political prisoners on Tuesday in Mashhad Central Prison, in northeastern Iran.
The five prisoners, identified as Farhad Shakeri, Abdolhakim Azim Gorgij, Abdolrahman Gorgij, Taj Mohammad Khormali, and Malek Ali Fadayi Nasab, were convicted of “armed rebellion” for their affiliation with banned political groups, according to Norway-based rights group Iran Human Rights (IHR).
In a statement on Wednesday, IHR said the five men were executed without the opportunity for a final visit with their families. Their executions came after years of detention, including long periods in solitary confinement and allegations of torture during their trials.
“These prisoners were subjected to torture and sentenced to death following an unfair trial in the Revolutionary Court,” said Mahmood Amiry-Moghaddam, Director of Iran Human Rights (IHR). "The international community and the people of Iran must respond seriously to these executions."
The executions of the five men came on the same day as Amnesty International warned that the vast majority of the executions in Iran last year were linked to political repression.
The rights group reported that Iran accounted for 64% of all known global executions in 2024, with at least 972 people executed, in what Amnesty said is the government's ongoing campaign of mass suppression of dissent.
The US Treasury on Thursday designated an Indian national and his tanker company along with other vessels and entities linked to exporting Iranian oil in contravention of US sanctions.
Jugwinder Singh Brar, chairman of Prime Tankers, along with seven other firms and 30 vessels were named in a notice published on the Treasury's Office of Foreign Assets Control Specially Designated Nationals and entities (SDN) list.
Many of the ships and companies had been cited by Washington-based advocacy group United Against a Nuclear Iran (UANI) as facilitators of Iran's energy sales.
