Negotiations between the United States and Iran have stretched into the early hours of Monday, with both delegations remaining at the Bürgenstock venue in Switzerland.
An American diplomat confirmed that talks continued through the night, signaling that the diplomatic process remains active despite a lack of immediate progress.
The sessions, which follow a preliminary understanding reached earlier in June, have been marked by a sharp tone and heated exchanges.
The Iranian nuclear program remains a central point of contention on the agenda, complicating efforts to finalize a broader peace framework.
The persistence of the talks suggests that neither side is willing to walk away, but the intensity of the debate indicates significant hurdles remain.
This development follows a period of stalled negotiations, where previous expectations for a swift consensus failed to materialize.
