Ongoing negotiations between Iranian and U.S. officials in Pakistan have continued through several rounds, with a third session extending late into Saturday night and into Sunday morning, according to Iranian state television.
Local media in Iran reported that another round of talks is expected, either later on Sunday or the following day, as reported by sources close to the negotiating team.
The meetings are being hosted in Pakistan following weeks of diplomatic engagement led by Islamabad, including efforts involving senior government and security officials.
However, major disagreements persist across several issues.
Tehran is also seeking sanctions relief and broader ceasefire guarantees, while the United States has maintained its position against easing restrictions on uranium enrichment and remains cautious over reopening strategic energy routes.
Differences also continue over Iran’s missile programme and the overall scope of the proposed truce, raising uncertainty over how quickly progress can be made.
Reports also indicate that discussions have moved into expert-level sessions involving technical and policy committees covering legal, economic and security matters.
Officials say earlier communication between the delegations had been indirect before shifting to direct engagement in Islamabad.
The talks come amid heightened regional tensions that have disrupted energy markets and raised concerns over inflation, food security and global economic stability.
