A framework peace deal between the US and Iran has been reached, Donald Trump and senior Iranian officials have said, bringing the 15-week conflict to a tentative end and offering hope of relief for the Middle East and the world economy.

The secretariat of Iran’s Supreme National Security Council said war and military operations on all fronts, including Lebanon, would end permanently from Monday night.

Preliminary agreement between Washington and Tehran has prompted anger in Israel, and widespread criticism of Netanyahu’s leadership

Benjamin Netanyahu has hailed a historic victory over Iran and ruled out any immediate withdrawal from Lebanon, saying that Israel’s forces would remain there “for as long as necessary”.

“We established deep security zones around the State of Israel. We did this in Gaza, in Lebanon, and in Syria,” the Israeli prime minister said in a televised press conference on Monday. “And I want to make it clear: we will remain in these security zones … to protect our country.”

In much of the Middle East, news that the US and Iran had come to a fragile agreement was greeted with relief tempered with doubt that any deal would resolve the turbulent region’s deep problems or even prevent a future return to war.

US president says in online post he reserves ‘ultimate alternative’ if Tehran refuses to sign agreement

Donald Trump said on Saturday that the US is set to sign a new agreement with Iran the following day, claiming that the deal would prevent Tehran from obtaining a nuclear weapon, as well as reopen the strait of Hormuz to international shipping.

In a Truth Social post, Trump said that Iran “no longer want a Nuclear Weapon, nor will they have one, either through purchase, development, or any other form of procurement”.

Donald Trump has declared that the strait of Hormuz will be “completely open” from Friday, as western leaders gathering at the G7 summit in Évian-les-Bains battled to prevent the fragile US deal with Iran from almost immediately unravelling.

“The deal’s all signed. And the strait ⁠is already partially opened,” Trump said as he arrived at the summit in France, but Israeli breaches of the ceasefire in Lebanon and Iran’s claims about its right to charge fees in the crucial waterway revealed the agreement’s many loose ends.

US president dismisses Iranian media reports agreement is close, despite earlier suggesting a deal could be signed this weekend

Prospects for an immediate end to the war between Iran and the US remained uncertain on Friday amid a chaotic series of conflicting claims and counter-claims by US and Iranian officials about ongoing negotiations.

Donald Trump seemed to distance himself from his earlier comments that suggested a preliminary agreement could be signed as soon as this weekend, with a series of angry social media posts describing the Iranians as “very dishonorable people to deal with”.
