Foreign Ministry spokesman Esmaeil Baqaei said Tehran had conveyed its concerns to the United States and that diplomatic contacts were continuing, although he declined to provide details of the latest exchanges.

Washington and Tehran have traded proposals since fighting began on Feb. 28, with only one direct round of talks held so far under a fragile ceasefire that has been in effect since April 8.

“As we announced yesterday, our concerns were conveyed to the American side,” Baqaei told reporters during a weekly press briefing, adding that negotiations were proceeding “through the Pakistani mediator.”

Baqaei reiterated Iran’s core demands, including the release of Iranian assets frozen overseas and the removal of longstanding US sanctions, saying Tehran’s negotiating team had consistently defended those conditions.

He also insisted that Iran’s request for war reparations remained justified, describing the conflict as “illegal and baseless.”

Iranian state-linked media reports suggested the latest US proposal sought major concessions from Tehran in exchange for limited relief measures.

According to Fars News Agency, Washington presented a five-point framework that included restricting Iran to a single operational nuclear facility and transferring its stockpile of highly enriched uranium to the United States.

The report said the United States had rejected demands to release a substantial share of Iran’s frozen assets and refused compensation for wartime damage. It also said Washington conditioned a full cessation of hostilities on Tehran entering formal peace negotiations.

Separately, Mehr News Agency criticized the US position as seeking concessions unattainable during the conflict itself, warning the demands risked deadlocking negotiations.

Iran’s earlier proposal, submitted last week, called for a complete halt to military operations across the region, including Israeli operations in Lebanon, and demanded an end to a US naval blockade imposed on Iranian ports since April 13.

Tehran also insisted it would maintain control over the Strait of Hormuz, a critical global energy shipping route that Iran has largely restricted since the outbreak of the conflict.

Baqaei said Iran remained prepared for any renewed military escalation if diplomacy failed.
