Iran's foreign minister says, according to state media, that the US response, which was submitted via mediator Pakistan, is now under review, reports the BBC.
The US has not formally confirmed the information, but Donald Trump wrote on Truth Social that the country's talks with Iran "could lead to something very positive for everyone."
The Iranian proposal includes 14 negotiation points. Among them are a formal end to the war within 30 days, lifting the blockade of the Strait of Hormuz, and postponing talks on the country's nuclear energy program - and, indirectly, possible nuclear weapons - to a later date.
Trump said on Saturday that he had received the proposal, but added that "I can't imagine that it will be acceptable because they haven't yet paid a high enough price for what they have done to humanity and the world over the last 24 years."
