The White House has confirmed that a new Iranian proposal aimed at ending the war is under discussion, while reiterating that US core conditions remain unchanged.

Press Secretary Karoline Leavitt said the proposal is being reviewed, but emphasised that Washington’s “red lines” continue to stand.

The statement comes as Iran says it is considering a US request to restart negotiations, a development seen as a possible shift in diplomatic engagement, although Tehran has not yet issued a formal response.

Iranian officials say the main obstacle to progress remains the nuclear dispute alongside broader security concerns. Tehran has reportedly put forward a framework in which an end to hostilities would come first, followed by security guarantees before wider negotiations begin.

Iran has also raised concerns over trust, citing previous US military actions during ongoing diplomatic talks.

Tehran is seeking assurances against further attacks during any negotiation process, while proposing that discussions on its nuclear programme and other issues be addressed at a later stage.

In return, Iran has suggested reopening the Strait of Hormuz as part of a broader settlement.

The conflict has significantly affected regional stability and global energy markets, prompting continued international calls for renewed diplomacy to prevent further escalation.
