Iran War Live Updates: Israel and Hezbollah Exchange Strikes, Complicating Possible Iran Peace Agreement

The attack came as the world waited nervously to see whether a cease-fire agreement between the United States and Iran was within reach after months of fighting across the Middle East that have killed thousands and roiled the global economy.

Mr. Trump said in a social media post on Saturday that a deal was “scheduled to get signed” on Sunday, and that it would immediately reopen the Strait of Hormuz, a critical shipping route that Iran has tried to control during the war.

But Esmail Baghaei, a spokesman for Iran’s foreign ministry, said a deal would not be signed on Sunday, though he left open the possibility that one could be agreed upon in the coming days, according to Iranian state media.

Neither the United States nor Iran has shared the text of the deal being considered, and it could still be derailed.

Lebanon has emerged as a critical stumbling block in the talks. Iran wants any broader peace settlement to end the fighting there and has called for the Israeli military to withdraw from Lebanese territory. But Israel, which is not directly involved in the U.S.-Iran negotiations, has said it would launch strikes in Lebanon if Hezbollah attacked its territory.

American and Iranian officials have said that under a “memorandum of understanding,” Iran would reopen the strait, the United States would lift its blockade on Iranian ports, and the cease-fire that the two sides agreed to in April would be extended for 60 days. During that period, both sides would commit to holding detailed negotiations over Iran’s nuclear program, and over the lifting of U.S. sanctions on Iran.

Prime Minister Shehbaz Sharif of Pakistan, which has acted as a mediator in the negotiations, had suggested over the weekend that an agreement could be finalized by Sunday, followed by an “electronic signing.” Diplomatic agreements are usually signed in person, and it was not immediately clear why this one might be finalized electronically.

Mr. Trump, who is expected to remain in Washington to celebrate his 80th birthday on Sunday, had previously said he would send Vice President JD Vance to attend the signing if a deal was finalized.

Here’s what else we’re covering:

• Diplomacy: A Qatari delegation visited Tehran on Sunday as part of the negotiations between Iran and the United States, according to Iranian news media and an official with knowledge of the situation. The official, who spoke on the condition of anonymity to discuss sensitive matters, said the Qataris, who have been acting as mediators, were helping to finalize the agreement in coordination with Washington.

• Opposition in Iran: There were signs on Saturday that some conservative factions in the Iranian government and the military were opposed to the peace agreement being negotiated, including criticism from two conservative lawmakers.

• Strait of Hormuz: Mr. Trump said in recent days that the U.S. military had been helping ships and oil move through the crucial waterway. But the number of ships passing through the strait is still far lower than it was before the war.
