Iran’s government accused the United States on Tuesday of sending mixed signals that are obstructing progress in ongoing nuclear negotiations, as tensions mount ahead of a possible sixth round of indirect talks.
Fatemeh Mohajerani, spokeswoman for the Iranian government, told reporters in Tehran that Washington’s “contradictory statements” were complicating the process and undermining trust.
“We are prepared for every scenario, but we will not leave the negotiating table,” Mohajerani said.
Reported offer diverges from US public line
A key source of friction is a draft proposal delivered to Iran on Saturday by Omani Foreign Minister Badr al-Busaidi, who has been mediating between Tehran and Washington.
The document outlines a possible framework under which Iran could maintain limited low-level uranium enrichment on its soil, according to Axios and other US media outlets.
This reported flexibility contrasts with public remarks from senior US officials, including White House envoy Steve Witkoff and Secretary of State Marco Rubio, who have repeatedly said Washington would not permit any uranium enrichment and would demand full dismantlement of Iran’s nuclear infrastructure.
The proposal also includes limits on future enrichment, the dismantling of certain facilities, and phased sanctions relief tied to compliance verified by the International Atomic Energy Agency (IAEA).
Tehran says proposal lacks guarantees
Iranian officials have responded skeptically. Foreign Ministry spokesman Esmaeil Baghaei said on Monday that the proposal lacked credible assurances on sanctions relief — a central Iranian demand.
A senior Iranian diplomat told Reuters the offer was a “non-starter,” citing inconsistencies between the US public position and what was conveyed in the draft.
Abbas Araghchi, Iran’s foreign minister, speaking during a visit to Cairo, confirmed that Tehran is still drafting its formal response.
Iran seen preparing negative response - Reuters
According to Reuters, a senior Iranian diplomat said Tehran is drafting a negative response to the US proposal, which could amount to a rejection. The unnamed diplomat cited by Reuters described the offer as failing to address Iran’s key demands, including recognition of its right to enrich uranium for peaceful purposes.
Sources close to Iran’s negotiating team also criticized what they view as Washington’s shifting stance, which they say has created uncertainty about US intentions and credibility, Iranian state media reported on Monday.
CNN on Monday also reported that the next round of nuclear talks is “very uncertain and may not happen at all,” citing sources familiar with the negotiations.
A senior Iranian official told the network the US proposal was “incoherent and disjointed” and conflicted with the understandings reached during the fifth round in Rome. The official added that “the fact that the Americans constantly change their positions” has become a major obstacle to progress.
US officials reject claim of bad faith
Israel Hayom reported on Monday that American officials expected Tehran to accept some elements and object to others.
The outlet, citing unnamed US sources, said that the administration believes Iran’s response will be more measured and that further talks remain possible. A US official quoted in the outlet said negotiators could begin by addressing areas where the gaps are narrower.
The official also said that negotiations would not continue indefinitely and that all options remain under consideration.
Trump publicly contradicts reported offer
President Donald Trump added to the confusion on Monday when he wrote on Truth Social: “Under our potential Agreement — WE WILL NOT ALLOW ANY ENRICHMENT OF URANIUM!”
The statement directly contradicts media accounts of the proposal delivered to Tehran, which permits limited enrichment under strict international oversight — a provision aimed at accommodating Iran’s long-standing demand for civilian nuclear rights.
The gap between Trump’s public stance and the reported content of the offer has become a central point of contention for Iranian officials, who accuse Washington of negotiating in bad faith.
US senator demands transparency over reported ‘side deal’
US Senate Majority Leader Chuck Schumer on Monday warned that the Trump administration may be pursuing a side arrangement with Iran outside the scope of congressional oversight.
Speaking on the Senate floor, Schumer cited the Axios report and urged the administration to clarify whether informal commitments have been made. He said the alleged deal, if true, contradicts earlier statements by Rubio and Witkoff and risks undermining accountability.
Schumer also said any future agreement must address not only nuclear safeguards but also Iran’s support for regional militant groups.
