Tehran holds back from talks to cement ceasefire due to ongoing Israeli attacks on southern Lebanon.

Planned talks in Switzerland between the United States and Iran to discuss the technical terms of their ceasefire deal have been postponed.

The Swiss Foreign Ministry confirmed early on Friday that the talks, which were scheduled to take place in Burgenstock, would now not go ahead.

Reports suggest that Iran has delayed sending its delegation to discuss the technical issues linked to the ceasefire deal – digitally signed by the two countries on Wednesday – due to Israel’s ongoing military campaign in Lebanon.

Israeli strikes overnight and into Friday have reportedly killed at least 16 people in southern Lebanon, with Iran-linked Hezbollah reporting intense fighting.

Talks postponed

A ceremony followed by talks was expected to be held at the Burgenstock Resort in Stansstad, near Lucerne in central Switzerland.

It is owned by Katara Hospitality, part of Qatar’s sovereign wealth fund, which helped mediate peace in the conflict.

On Friday, in a message to media outlet AFP, the Swiss foreign ministry said: “The planned talks between the US, Iran, Qatar and Pakistan have been postponed”.

“Switzerland remains ready to facilitate these talks. The relevant preparatory work at Burgenstock is continuing,” it added, without providing a new date for the talks.

The announcement followed a report from media outlet Al-Mayadeen that Iran was delaying sending its delegation to Switzerland over Israel’s ongoing military campaign in Lebanon.

Israeli Prime Minister Benjamin Netanyahu said Thursday that Israel’s military will stay in a “security zone” of southern Lebanon as long as “Israel’s security needs require it.”

Israel and Hezbollah are not parties to the agreement, but Iran has insisted Israel must withdraw from the large swath of southern Lebanon it is occupying.

Logistics have never been ‘simple or predictable’

The US push to quickly begin high-stakes talks with Iran hit a snag just two days after the signing of a 14-point memorandum of understanding with the US that sets out a framework for talks during a 60-day negotiation period.

Vice President JD Vance had been prepared to make an overnight flight to meet with his Iranian counterparts at the mountainside resort in the tiny Swiss village of Obburgen.

His staff and a small pack of journalists had even gathered at Joint Base Andrews outside Washington in anticipation of the trip.

Meanwhile, dozens of White House officials, advance staffers and more media gathered in Switzerland to prepare for Vance’s anticipated arrival.

But then, abruptly on Thursday evening, the trip was called off.

The White House issued a statement explaining Vance – who has been tapped by President Donald Trump to lead the negotiations – and his delegation were prepared for talks, but they were unable to finalise plans and the vice president would remain in Washington.

“The logistics of these negotiations have never been simple or predictable,” the statement noted.

Also on Thursday, Pakistan’s Prime Minister Shehbaz Sharif cancelled his trip to Switzerland, his spokesperson told AFP.
