A Qatari delegation comprising senior officials flew to Tehran on Sunday as part of efforts to finalise an agreement to end the US-Iran war, sources said on Sunday.

US and Pakistani leaders forecast a signing today of a framework agreement to end the more than three-month-long war, but Tehran cast doubt over the timing as hardline protesters in Iran voiced opposition.

The Qatari visit came as diplomatic efforts intensified to finalise the framework agreement aimed at ending the US–Iran conflict.

The visit comes amid mixed signals over the timing and status of the proposed deal, which US and Pakistani leaders had suggested could be signed on Sunday.

However, Iranian officials have not confirmed any immediate signing, and uncertainty persists in Tehran.

Iran’s ISNA news agency reported that an adviser to Qatar’s foreign minister had been dispatched to Iran, while Tasnim said the visit was aimed at reviewing “the latest developments in the diplomatic process.”

Separately, Iran’s Fars news agency, citing an informed source, said Tehran has not yet taken a final decision on the framework agreement.

It added that political, legal and technical assessments are still underway at expert and decision-making levels.

The developments come as hardline opposition voices in Iran have also expressed resistance to the emerging understanding, adding further uncertainty to the timeline of any potential deal.

Despite earlier signals of progress, the status of the agreement remains fluid, with negotiations continuing through intermediaries.
