Iran's delegation arrived in Switzerland ahead of planned talks with the United States, the Swiss Foreign Ministry announced on X/Twitter late Saturday night.
The delegation includes Iranian Foreign Minister Abbas Araghchi and Iranian Parliment Speaker Mohammed-Bagher Ghalibaf.
Ghalibaf announced his arrival in a post on X, sharing a photo of himself standing in front of a plane painted with the hashtag "Minab 168" in English and Persian beside the flag of the Iranian regime.
US Vice President JD Vance later arrived in Switzerland on Sunday for what he has said would likely be a couple of days of peace talks with Iranian officials. Vance and his wife arrived at Emmen Air Base in Switzerland at 5:59 a.m., a vice presidential spokesperson said.
US Special Envoys Jared Kushner and Steve Witkoff have reportedly already arrived in Switzerland for the talks.
Additionally, Pakistani Prime Minister Muhammad Shehbaz Sharif and Pakistan's Chief of Staff also departed Islamabad during the night to take part in the negotiations.
The meeting, which had been originally meant to take place on Friday, follows the signing of the Memorandum of Understanding (MoU) between the US and Iran by US President Donald Trump and Iranian President Hassan Rouhani in France last week.
Vance and Ghalibaf digitally signed the agreement, with Trump witnessing the signing, according to the US official.
The White House published footage of the signing on an X post on Thursday.
