Iran has proposed a 10-point peace plan to end the war as the United States and Israel intensify their attacks on Tehran and a deadline looms that was set by US President Donald Trump for Iran to open the Strait of Hormuz, whose near-closure has triggered a global energy crisis.

At the White House on Monday, Trump called the 10-point plan a “significant step” but “not good enough”.

Iran’s top university and a major petrochemical plant were hit on Monday after Trump threatened to target power plants and bridges until Tehran agreed to end the war and open the strait, through which 20 percent of the world’s oil and gas supplies pass.

Here is more about Iran’s 10-point plan and Trump’s response to it:

What is Iran’s 10-point plan?

On Monday, Pakistan, which has mediated talks in Islamabad aimed at ending the war, put forth a 45-day ceasefire proposal after separate meetings with US and Iranian officials. The Iranian and US negotiators have not met face to face about the 45‑day truce plan. In late March, Trump told reporters that his envoys were talking to a senior Iranian official, but this was not confirmed by Iran. Tehran has denied holding talks with US negotiators.

Iran’s state-run IRNA news agency said Tehran had conveyed its response via Islamabad. Iran reportedly rejected the proposed ceasefire, putting forward instead a call for a permanent end to the hostilities.

The Iranian proposal consisted of 10 clauses, including an end to conflicts in the region, a protocol for safe passage through the Strait of Hormuz, the lifting of sanctions and reconstruction, IRNA reported. The conflict has spread to the Gulf region and Lebanon, where 1.2 million Lebanese people have been displaced due to Israeli attacks.

Details about the 10 clauses have not been published.

How did the White House respond?

Speaking to reporters about Iran’s plan, Trump said: “They made a … significant proposal. Not good enough, but they have made a very significant step. We will see what happens.”

“If they don’t make a deal, they will have no bridges and no power plants,” he added.

In a profane Truth Social post on Sunday, Trump threatened to attack Iran’s civilian infrastructure, including bridges and power plants, if the Strait of Hormuz is not fully reopened. “Tuesday will be Power Plant Day, and Bridge Day, all wrapped up in one, in Iran. There will be nothing like it!!! Open the F****** Strait, you crazy bastards, or you’ll be living in Hell – JUST WATCH! Praise be to Allah,” he wrote.

The deadline is set for 8pm Washington time on Tuesday (00:00 GMT). Tehran has rejected this ultimatum and threatened to retaliate.

Human rights organisations and members of the US Congress have criticised Trump for threatening to attack civilian targets, which is considered a war crime.

The Axios news website reported that an unnamed US official who saw the Iranian response called it “maximalist”.

What other proposals have been on the table?

The last time the word “maximalist” was used to describe a peace plan in this war was late last month when Iran called a US plan “maximalist”.

An unnamed, high-ranking diplomatic source told Al Jazeera on March 25 that Iran had received a 15-point plan drafted by the US. The plan was delivered to Iran through Pakistan.

The source said Tehran described the US proposal as “extremely maximalist and unreasonable”.

“It is not beautiful, even on paper,” the source said, calling the plan deceptive and misleading in its presentation.

The 15-point plan included a 30-day ceasefire, the dismantling of Iran’s nuclear facilities, limits on Iran’s missiles and the reopening of the Strait of Hormuz.

In return, the US would remove all sanctions imposed on Iran and provide support for electricity generation at Iran’s Bushehr Nuclear Power Plant.

Iran has rejected a temporary ceasefire, arguing it would give the US and Israel time to regroup and launch further attacks. Tehran has pointed to Israel’s 12-day war on Iran in June. The US joined that conflict for one day, hitting Iran’s three main nuclear sites with air strikes. Trump claimed at the time that the US had destroyed Iran’s nuclear facilities but months later justified the current war by saying Iran posed an imminent threat.

The UN nuclear watchdog, however, said Iran was not in a position to make a nuclear bomb.

The US and Israel launched the war on February 28 as Washington was holding negotiations with Iran. On the eve of the war, Oman, the mediator of the talks, had said a deal was “within reach”.

Tehran has said for years that its nuclear programme is for civilian purposes and it does not intend to create nuclear weapons. It even signed a deal with the US in 2015 to limit its nuclear programme in exchange for sanctions relief. But Trump withdrew from the landmark deal in 2018 and slapped sanctions back on Iran.

In response, Iran decided to enrich uranium from 3.6 percent, which was allowed under the 2015 deal, to almost 60 percent after its Natanz nuclear facility was bombed in 2021. Iran blamed Israel. A 90 percent level of purity is required to make an atomic bomb.

Why does this matter?

With Tuesday’s deadline fast approaching, chances for a ceasefire appear remote as the two sides remain far from agreement and the conflict is now in its second month.

On Tuesday, Reza Amiri Moghadam, Iran’s ambassador to Pakistan, posted on X: “Pakistan positive and productive endeavours in Good Will and Good Office to stop the war is approaching a critical, sensitive stage …”
