LIVE | Trump to send delegation to Pakistan Monday for negotiations, warns Iran: 'NO MORE MR. NICE GUY!'

Vice President J.D. Vance will head the U.S. delegation for talks with Iran in Pakistan, a White House official said Sunday, after President Donald Trump indicated otherwise.

Vance, special envoy Steve Witkoff and Trump's son-in-law Jared Kushner will attend the dialogue, a White House official told AFP on condition of anonymity, when asked about the composition of the delegation following Trump's remarks.

Donald Trump announced Sunday that a U.S. delegation will be in Pakistan on Monday to resume negotiations with Iran, while threatening to destroy Iran's infrastructure if the talks fail.

In a message on Truth Social, Trump also accused Tehran of violating the two-week ceasefire initiated on April 8 by launching attacks on Saturday in the Strait of Hormuz.

The U.S. president said he was offering Iran a "reasonable deal" and that, in case of Tehran's rejection, "the United States is going to knock out every single Power Plant, and every single Bridge, in Iran."

"They’ll come down fast, they’ll come down easy and, if they don’t take the DEAL, it will be my Honor to do what has to be done, which should have been done to Iran, by other Presidents, for the last 47 years," he said.

"NO MORE MR. NICE GUY!" he warned.

Trump posted Sunday, "Iran decided to fire bullets yesterday in the Strait of Hormuz — A Total Violation of our Ceasefire Agreement!"

A post attributed to Mojtaba Khamenei, Iran's supreme leader, on the ayatollah's Telegram account again threatened the U.S. and Israel with "bitter defeats" at the hands of the Iranian navy.

"Just as Iranian drones strike like lightning against the U.S. and Zionist criminals, Israel, the brave Navy is also ready to inflict a new bitter defeat on the enemies."

​​The Israeli military said Sunday that a soldier was killed in combat in southern Lebanon, where a temporary truce is in effect. This was the 15th Israeli soldier killed in fighting with the pro-Iranian militant group Hezbollah in Lebanon.

The Revolutionary Guards, Iran's ideological army, warned on Saturday that any ship approaching the strategic Strait of Hormuz will be"taken as a target."

In the morning, Iran announced the closure of that crucial passage for hydrocarbon trade that had been reopened for commercial shipping Friday afternoon.

Peace negotiations between Iran and the United States have "registered progress," but a final agreement "remains far off," the powerful speaker of the Iranian Parliament, Mohamad Bagher Ghalibaf told local television on Saturday.

Pakistan's army chief conveyed U.S. "new proposals" to Iran, Iran's Supreme National Security Council, announced, as quoted by the official IRNA agency.

"Iran is studying them and has not yet responded," the body said. However, the negotiating delegation of Iran "will not make even the slightest concession," it warned.

The internet outage imposed by Iranian authorities at the start of the war entered its 50th day, cybersecurity monitoring NGO NetBlocks said.

"The negotiations conducted by the state do not concern us," said Mahmoud Qamati, vice chairman of Hezbollah's political bureau in an appearance in the southern suburbs of Beirut, a stronghold of the pro-Iranian terror group.

Nothing prevents "the state from coordinating with us" in any initiative aimed at "preserving sovereignty, but not in this way that leads us to capitulation," he added.
