Iranian President Masoud Pezeshkian signs the document of US Memorandum of Understanding in Tehran, Iran [West Asia News Agency/Reuters]By Elizabeth Melimopoulos and ReutersPublished On 19 Jun 202619 Jun 2026
United States Vice President JD Vance has delayed his planned trip to Switzerland to start a new round of peace talks with Iran following the signing of a memorandum of understanding (MoU) to end the war, the White House has said.
Vance earlier defended the agreement between Washington and Tehran amid criticism from US officials and Israel, saying the signing of an MoU has launched a 60-day negotiating period towards a final deal.
Vance and his team were reportedly ready to leave for Switzerland on Thursday night, but the trip was cancelled at the last minute following Israeli bombing in southern Lebanon, killing at least three people, overnight.
Iran’s semi-official Tasnim news agency reported that there was no confirmation that Iranian negotiators would travel for talks, because they first wanted to see signs that the interim agreement, which includes Lebanon in the US-Iran ceasefire, was being implemented.
The agreement, signed by the presidents of both countries, has been presented as a step towards ending months of conflict, though critics have questioned its terms, the number of questions it leaves unanswered and Tehran’s commitment to it.
