Diplomatic efforts between the United States and Iran have stalled in Switzerland, where face-to-face talks were expected but delayed amid mounting tensions across the region. The negotiations, hosted at a Swiss mountain resort in Burgenstock with mediation from Qatar and Pakistan, were meant to advance a framework agreement covering sanctions relief, nuclear commitments, and regional de-escalation.

The escalation has further complicated efforts to move forward with the US-Iran understanding.
