Negotiations between US and Iranian delegations in Switzerland have reportedly broken down after the Iranian representatives unexpectedly left the talks, according to Iran’s Tasnim news agency citing a source close to the Iranian negotiating team. No official confirmation of the walkout has been released as of yet. The reported disruption follows earlier statements from US Vice President J.D. Vance, who indicated significant progress had been made in the discussions. The reason for the Iranian delegation’s departure remains unclear. This development casts doubt on the possibility of a near-term resolution to ongoing issues between the two countries. The talks were scheduled to take place on Sunday, but were cut short. Further updates are pending official statements from both sides.
