Middle East crisis live: Trump rejects Iran’s response to US peace deal; UN urges ‘genuine ceasefire’ as Israel intensifies Lebanon strikes

Donald Trump has rejected Iran’s response to a U.S. peace proposal as unacceptable, according to Reuters reporting, even as the United Nations warns that the humanitarian situation in Lebanon is deteriorating.

The developments keep multiple fronts of the Middle East crisis in focus at once: the U.S.-Iran diplomatic track, maritime security in the Strait of Hormuz and Israel’s continuing strikes in Lebanon.

Trump rejects Iran’s proposal

Reuters reported that Iran’s counterproposal focused on ending the war, gaining sanctions relief, securing guarantees over the Strait of Hormuz and obtaining other concessions. Trump’s response, reported on May 10 and May 11, was that the proposal was not acceptable.

The rejection leaves the status of the peace effort unclear and raises the possibility that the diplomatic channel could slow or stall.

UN warns on Lebanon

At its May 11 noon briefing, the UN said Lebanon’s humanitarian situation continued to worsen despite the April 17 ceasefire. The organization said more than 100 strikes were reported in Lebanon in the previous 24 hours and that 87 people were killed over the weekend.

Tom Fletcher, speaking for the UN, called for a genuine ceasefire and said attacks on humanitarian and medical personnel are unacceptable.

Why it matters

The two developments underline how fragile the wider regional picture remains. Even as diplomats and intermediaries look for a way forward on Iran, the fighting in Lebanon is continuing and putting more pressure on ceasefire arrangements.

The next steps are uncertain. It is not yet clear whether the Trump-Iran talks resume, whether new diplomatic messages follow, or whether the Lebanon ceasefire violations prompt a fresh intervention.

For now, the immediate picture is one of continued escalation on the ground and a stalled diplomatic response.
