May 6 (Reuters) - The White House believes it is getting close to an agreement with Iran on a one-page memorandum of understanding to end ‌the war and set a framework for more detailed nuclear negotiations, Axios ‌reported on Wednesday, citing two U.S. officials and two other sources briefed on the issue.

The U.S. expects ​Iranian responses on several key points in the next 48 hours, according to the report which cautioned that nothing has been agreed yet but said this was the closest the parties had been to an agreement since the war began.

Among other provisions, the deal ‌would involve Iran committing to ⁠a moratorium on nuclear enrichment, the U.S. agreeing to lift its sanctions and release billions in frozen Iranian funds, and both sides ⁠lifting restrictions around transit through the Strait of Hormuz, Axios said.

The one-page, 14-point memorandum of understanding is being negotiated between U.S. envoys Steve Witkoff and Jared Kushner and several ​Iranian officials, ​both directly and through mediators, the report ​said.

In its current form, the memorandum ‌would declare an end to the war in the region and the start of a 30-day period of negotiations on a detailed agreement to open the strait, limit Iran's nuclear programme and lift U.S. sanctions, Axios added.

Iran's restrictions on shipping through the strait and the U.S. naval blockade would be gradually lifted during that 30-day period, ‌Axios said, citing one U.S. official who added ​that if the negotiations collapse, U.S. forces would ​be able to restore the blockade ​or resume military action.

Iran said earlier on Wednesday it would accept ‌a peace deal only if it ​was "fair", after U.S. President ​Donald Trump paused a three-day-old naval mission tasked with reopening the Strait of Hormuz that had shaken the war's month-old ceasefire.

Reuters could not immediately verify the ​report. The U.S. State ‌Department and White House did not immediately respond to a request for ​comment.

U.S. stock index futures extended gains following the Axios report.
