Tehran would restore shipping through the Strait of Hormuz to pre-war levels within a month in a framework deal with the US to also include withdrawing US forces from Iran's vicinity, Iranian state television reported on Wednesday. The report said the US would end a naval blockade of Iranian shipping, citing a memorandum of understanding being negotiated between the two sides to end the war which has choked global energy supplies through the strategic waterway.
Iranian state TV said it had obtained an unofficial draft of the MOU though it was not final and may not be agreed. The US denied the report, saying it was "complete fabrication" in a White House statement on social media.
Iran's government did not comment. The issue of US troops in the region also needs further discussion, the TV report said without being more specific.
There was no mention of Iran's nuclear program which the US wants disbanded.
The state TV report was the latest signal of possible progress towards a deal, although publicly Tehran and Washington have outlined positions starkly at odds and the potential terms outlined by the broadcaster did not appease all US demands.
US Secretary of State Marco Rubio said on Tuesday it may take a few more days, after President Donald Trump had raised hopes over the weekend for an imminent end to the war.
Key sticking points have included reopening and management of the waterway through which a fifth of the world's oil and liquefied natural gas flowed before the conflict and the dismantling of Iran's nuclear capacity.
Oil prices fell more than 5% on Wednesday after the Iranian TV report.
It was not immediately clear what a US military pullback as described by Iranian state television would look like.
US naval vessels, some with thousands of sailors and Marines aboard, regularly transit the region, stopping in ports including in Oman.
