In a Fox News interview on Saturday, Vance said that he expected to travel to Switzerland for the talks soon and that the talks could begin as early as Sunday.

Also on Saturday, Iran's main military command Khatam al-Anbiya Central Headquarters announced the closure of the Strait of Hormuz, citing the U.S. "breach" of the newly-signed peace memorandum of understanding and Israel's ceasefire "violations" in southern Lebanon as reasons.

Vance said there is no evidence that Iran is closing the Strait of Hormuz.

"We're not seeing any evidence that the Iranians are still closing down the Strait of Hormuz. It is going to take some time to clear those mines, though," Vance told Fox News.
