US warns of military action as Iran rejects deal without full guarantees

The US signals readiness to resume military action against Iran amid stalled nuclear talks and disputed terms, with Tehran demanding full rights guarantees before agreeing to any deal.

What happened

France 24 reports that the United States has warned it is prepared to restart military action against Iran if necessary, following President Donald Trump's reiteration that any peace agreement must prevent Tehran from ever developing nuclear weapons. Despite US signals of a nearing deal, Iran’s chief negotiator stated that Tehran will not accept any arrangement without full guarantees of its rights.

Outside Brief is treating this as a source-led account. Any disputed responsibility, casualty figure or battlefield claim should be read as unconfirmed/hearsay unless confirmed by another reliable source. The White House conveyed that Trump remains firm on red lines, especially on restricting Iran’s nuclear capabilities and reopening the blockaded Strait of Hormuz without Iranian tolls. However, Iranian officials have denied any final agreement, insisting negotiation messages are ongoing, and pushed back against conditions labeled as ultimatums.

Additionally, conflicting reports emerged over financial terms. Iranian sources cited by state media claim Tehran demands the immediate release of $12 billion in frozen assets before progressing, with an unofficial draft reported to allow Iran access to these funds within 60 days. The White House has dismissed such claims as false. Both sides dispute the inclusion of key clauses reportedly claimed by their counterparts.
