Iran live updates: US talks with Iran postponed

At least 18 people have been killed and 33 people injured in Israeli strikes across 11 different towns and villages in southern Lebanon overnight, according to the Lebanese Ministry of Public Health.

The death toll is preliminary and ongoing strikes are preventing first responders from reaching victims, the ministry said.

One Israeli strike on a residential building in Al-Duwair killed at least three people, according to the health ministry and the Lebanese state news agency NNA.

Elsewhere, four Israeli soldiers were killed overnight in southern Lebanon, the Israel Defense Forces said, when an IDF tank was hit by a "suspicious target" just past midnight local time. Among those killed was a Lieutenant Colonel, officials said.

"Following the incident, the IDF struck numerous Hezbollah infrastructure sites in Nabatieh and additional areas," the IDF official said.

The planned talks between the United States and Iran meant to take place on Friday have been postponed, the Swiss Ministry of Foreign Affairs announced early Friday.

Preparations for future talks are continuing in Bürgenstock, officials said, but the ministry did not share details about when they could possibly be held.

"The planned talks between the U.S., Iran, Qatar and Pakistan have been postponed," the Swiss Ministry of Foreign Affairs said in a statement. "Switzerland remains ready to facilitate these talks. The relevant preparatory work at Bürgenstock is continuing. No further information can be provided at present.

It was announced late Thursday that U.S. Vice President JD Vance would not be traveling to Switzerland for initial negotiations on the implementation of the memorandum of understanding with Iran, according to the White House.

Vice President JD Vance will not be traveling Thursday night to Switzerland for initial negotiations on the implementation of the memorandum of understanding with Iran, the White House said.

"As the Vice President said at his press conference, the plans for the upcoming technical talks have not been finalized, and the U.S. delegation has been prepared to depart at the first available opportunity," a White House spokesperson said. "But the logistics of these negotiations have never been simple or predictable. As of now the Vice President is not departing tonight."

The statement went to say that the White House will provide "next steps" as soon as there is a "concrete update."

President Donald Trump defended the memorandum of understanding, saying in a pre-taped interview with Axios that "it probably is unconditional surrender" for Iran.

While discussing how it compares to the initial goals at the onset of the war, a reporter said the MOU doesn't look like unconditional surrender.

"Well, really, it probably is unconditional surrender," Trump responded, in a clip of the interview released by Axios.

In another clip, when asked what he had learned about the limits on his power as a result of the conflict, Trump responded, "There are no limits," adding that's a lesson he has yet to learn because "we defeated them totally militarily."
