TASNIM NEWS, citing sources, says Iran's delegation walked out of talks in protest at comments by Trump.

US Vice President Vance departed for Switzerland to attend US‑Iran talks, saying he expects to be there one to two days and hopes Washington and Tehran can make progress on Iran’s nuclear file and a Lebanon ceasefire. He added that, despite headline coverage, the situation in Lebanon is improving and cooling, but will require sustained management to ensure security and stability for Israel and Lebanon.

U.S. Vice President Vance said President Trump has asked us to "open a new chapter" to change our relationship with the Iranian people.
