US Vice President JD Vance is in Switzerland for the first round of negotiations with Tehran, seeking Iran's invitation for UN inspectors to visit its nuclear sites in exchange for releasing $6 billion in frozen funds.
The US is reportedly willing to release some of the Islamic Republic's frozen funds, starting with a $6 billion account in Qatar, to be used for humanitarian purposes.
The talks are part of a 60-day negotiation period, following an interim peace deal signed by US President Donald Trump and Iranian president Masoud Pezeshkian.
A US intelligence report has warned that Israeli Prime Minister Benjamin Netanyahu may hinder the US-Iran peace talks amid growing domestic pressure over the country's situation with Lebanon.
