Iran live updates: G7 leaders 'support,' 'ready to contribute' to US-Iran MOU

The U.N. is seeing a "significantly reduced level" of violence and exchanges of fire in southern Lebanon since the weekend, Stéphane Dujarric, spokesperson for the U.N. secretary general, said on Tuesday.

"The mission recorded 38 violations of Lebanese airspace by the Israel Defense Forces (IDF) yesterday, down from 83 reported on Sunday," Dujarric said at his daily press briefing.

On the continued displacement of people from southern Lebanon, Dujarric said, "while violence has decreased since Sunday, incidents in southern Lebanon continue to be reported, which has a direct impact on people’s ability to check on their homes or to move around."

The G7 leaders released early on Wednesday a joint statement on geopolitical issues, including the US-Iran deal, saying the group welcomes the MOU that could "prevent Iran from acquiring any nuclear weapon and tackling the threats related to its regional and ballistic activities."

"We support and are ready to contribute to its implementation," the leaders of Canada, France, Germany, Italy, Japan, the United Kingdom and the United States said in a written statement.

The statement highlighted the reopening of the Strait of Hormuz, emphasizing that the critical passageway should operate "without restrictions or tolls," calling it "the bedrock of international trade."

"We agree that the multinational, independent, and defensive initiative led by France and the UK can play an important role to facilitate the resumption of maritime traffic in the Strait of Hormuz by protecting merchant vessels, reassuring commercial shipping operators, and supporting verification that all mines are removed," the leaders added.

In an interview with CNN that was aired Tuesday night, Canadian Prime Minister Mark Carney said he has seen the MOU, calling it "well-structured" and a "game-changer." The Canadian prime minister did not confirm the exact length of the document, but called it a "reasonable" length.

In the joint geopolitical statement, the G7 leaders also emphasized their support for an "immediate robust ceasefire" in Lebanon -- where Israel has been attacking targets it says are associated with Hezbollah, the Iran-backed militia -- along with the protection of Lebanon’s "territorial integrity and sovereignty," while also reiterating efforts to disarm Hezbollah.

Vice President JD Vance said that President Donald Trump could release the text of the memorandum of understanding as soon as Wednesday, but tried to downplay its release overall.

"The president said by the latest Friday, possibly as early as tomorrow, we're going to release the memorandum of understanding text," Vance said on Megyn Kelly’s radio show Tuesday.

"Fundamentally, does it really matter if the deal comes out on Wednesday versus Friday? No. That's why we haven't emphasized it so much is because at the very latest, the text is going to be out on Friday," Vance said.

The vice president also reiterated that any financial relief, including sanctions relief and the release of frozen assets, would be tied to Iran’s behavior.

Vance said that enrichment was "on the table" in the along with verification and inspection, though it was not clear if this was an agreement to limit all enrichment.

"If they want the benefits of the bargain, enrichment is going to be on the table and more importantly verification and inspections is going to be on the table," Vance said.

Intelligence gathered by U.S. agencies presents a pessimistic outlook on whether the Iranian regime will ultimately agree to nuclear concessions sought by the Trump administration during detailed negotiations set to take place in the coming weeks, according to two U.S. officials familiar with the matter.

The findings, which are largely based on signals intelligence gathered from senior Iranian officials, were presented to the president and other members of his cabinet by CIA Director John Ratcliffe in the days before the memorandum of understanding with Iran was electronically signed, they said.

Israel has also shared intelligence with the U.S. that suggests Iran will not agree to a final deal the Trump administration would deem acceptable, but it’s unclear whether the president was briefed on those findings, one official said.

The findings of the U.S. agencies appeared to deepen skepticism among the more hawkish members of the president’s cabinet, including Ratcliffe, Secretary of State Marco Rubio and Secretary of Defense Pete Hegseth, the officials said, adding that they have also privately expressed doubt Iran will comply even with the terms included in the memorandum of understanding.
