Qatar,
Turkiye and
Egypt have presented
Iran and the
United States with a framework of key principles to be discussed in talks on Friday this week, including a commitment by
Iran to significantly limit its uranium enrichment, two sources familiar with the negotiations have told
Al Jazeera.Key points in the proposed framework also include restrictions on the use of ballistic missiles and the arming of
Iran’s allies in the region, according to the sources, who include a senior diplomat who asked to remain anonymous due to the sensitive nature of the talks.Recommended Stories list of 3 itemslist 1 of 3Will

Al Jazeera that the talks, which US special envoy
Steve Witkoff and Iranian Foreign Minister
Abbas Araghchi are expected to attend, will take place in
Oman and not
Turkiye as previously planned.This slim window for diplomacy comes as the region braces for a potential US attack on
Iran after President
Donald Trump ordered forces to amass in the
Arabian Sea following a violent crackdown by
Iran on protesters last month.What is in the proposals?Under the proposed framework for an agreement,
Iran would commit to zero enrichment of uranium for three years. After that, it would agree to limit enrichment of uranium to below 1.5 percent.Its current stock of highly enriched uranium – including about 440kg (970lb) that has been enriched to 60 percent – would be transferred to a third country.The proposed framework goes beyond
Iran’s nuclear programme with mediators proposing that
Iran should agree not to transfer weapons and technologies to its regional, nonstate allies.Tehran would also pledge to not initiate the use of ballistic missiles under this framework. This falls short of a US demand that
Iran curb the number and range of its ballistic missiles.A “nonaggression agreement” between Tehran and Washington is also being proposed by the three mediators, one of the sources said.It is not yet known how Washington or Tehran have responded to the proposed framework.For its part, the US has made it clear that any deal must include regulations on
Iran’s nuclear programme, missiles and proxies.In the past,
Iran has been willing to compromise on nuclear development, including in 2015 when it signed the Joint Comprehensive Plan of Action (JCPOA), a nuclear deal with other countries, including the US, to limit nuclear enrichment in exchange for sanctions relief. Three years later, however, Trump pulled the US out of the agreement.But Tehran has so far refused to talk about limiting its support for nonstate allies in the region and curtailing its ballistic missiles.On Wednesday,
Iran was still holding firm to the line that it would “exclusively” discuss the nuclear programme and the lifting of sanctions, the semiofficial Tasnim news agency reported.Defiant toneThe mediators’ framework was presented to the US and
Iran just before Witkoff met with Israeli Prime Minister Benjamin Netanyahu and his spy chiefs during a visit to Israel on Tuesday.The US is entering negotiations with significant leverage as
Iran faces an unprecedented mix of external and internal pressures.A US aircraft carrier, fighter jets and navy destroyers are now positioned in the
Arabian Sea, presenting Tehran with a credible military threat.Meanwhile,
Iran has been rocked by nationwide protests in December and January, which culminated in the country’s most brutal episodes of violence in decades.Still, Supreme Leader Ali Khamenei has maintained a defiant tone, and observers remained cautious about whether he would be willing to compromise on key issues, considering the degree of mistrust towards the US in Tehran.Reviving diplomacyThis is not the first time Iranian and US officials have met in a bid to revive diplomacy between the two nations, which have not had diplomatic relations since 1980. In June, US and Iranian officials gathered in the Omani capital, Muscat, to discuss a nuclear agreement, but the process stalled as Israel bombed
Iran.The Israeli strikes kicked off a 12-day war, which ended with the US bombing key Iranian nuclear facilities and
Iran making a symbolic strike on Al Udeid military base in
Qatar, which hosts US forces.Since then, Tehran has claimed it has replenished its stockpile of ballistic missiles and has warned countries it would use them if attacked. Washington is particularly eager to limit
Iran’s ballistic missiles because, during the 12-day war, some Iranian missiles succeeded in breaching Israel’s much-vaunted Iron Dome defence system.In the meantime, tensions remained high. On Tuesday, the US shot down an Iranian drone that had come close to the USS Abraham Lincoln aircraft carrier. And on the same day, US officials said Islamic Revolutionary Guard Corps forces had harassed a US-flagged, US-crewed merchant vessel in the Strait of Hormuz, a Gulf waterway critical to global trade.
