Iranian news agency IRNA, in reporting carried by several Persian-language outlets, said the delegations interrupted the meeting at the Bürgenstock venue for internal consultations. The pause was presented as procedural rather than as a breakdown, with reports indicating that further discussions were expected after the delegations reviewed their positions.
The meeting brought together Iranian and US representatives alongside Qatari and Pakistani mediators. According to Eghtesad Online, which cited IRNA, the talks were convened to follow up on commitments contained in the so-called Islamabad memorandum, a framework that Iranian officials portray as a precursor to any wider agreement rather than a final settlement.
Iran’s opening position appeared deliberately narrow. Eghtesad Online, citing Iranian officials, reported that Tehran’s delegation had been instructed to press five implementation demands: an end to hostilities on all fronts, a halt to Israeli military operations in Lebanon, sanctions relief—particularly measures affecting Iran’s oil sector—and compliance with other commitments attributed to Washington.
Iranian Foreign Ministry spokesman Esmaeil Baghaei said the Swiss meeting was meant to test whether the other side would carry out those commitments in practice. As quoted by Eghtesad Online, Baghaei said Tehran did not intend merely to sign a document and assume that its provisions would automatically be implemented. He argued that beginning negotiations toward a final agreement was conditional on progress on five specified provisions, including the first clause concerning an end to war on all fronts, Lebanon included.
That condition helps explain why the Lebanon file has become the immediate obstacle. Persian-language coverage has consistently portrayed the continuation of Israeli attacks in Lebanon as a direct challenge to the basis of the memorandum. The Iranian side’s argument is that no broader technical or political process can move forward while the first, security-related commitment remains unfulfilled.
The talks are also taking place under pressure from competing accounts of their agenda. Eghtesad Online reported that Iranian state television denied that Iran’s nuclear programme had been discussed during the opening 80-minute session. Yet the same outlet cited CNN, which reported—on the basis of diplomatic sources—that the wider Swiss discussions involved the Lebanon war, the Strait of Hormuz and Iran’s nuclear stockpile. The divergence underscores that the parties may be approaching the meeting with different priorities, or may be deliberately limiting public disclosure of sensitive issues.
Iranian reporting has further emphasised oil sanctions as a central component of the negotiations. IRNA reported that the head of the National Iranian Oil Company, who was part of Iran’s delegation, said that the removal of oil-related sanctions and exemptions had been pursued during the talks. That emphasis suggests Tehran is seeking tangible economic measures alongside security commitments, rather than accepting a process confined to regional de-escalation.
Earlier reports also indicated that Pakistani and Qatari mediation remains central. Tehran has asked both governments to use their role in the process to ensure what it describes as full and continuous US compliance with the memorandum. Before the main session, Iran’s delegation held separate discussions with Pakistani Prime Minister Shehbaz Sharif and Qatari Prime Minister Mohammed bin Abdulrahman Al Thani, according to Eghtesad Online.
For now, the pause appears to reflect a need for the parties to reassess their positions rather than an outright suspension. But the political meaning is clearer: Tehran is attempting to make any further US-Iran process conditional on verifiable changes on the ground in Lebanon and on concrete sanctions relief. Whether the mediators can bridge that gap will determine whether the Switzerland channel develops into sustained negotiations or remains limited to crisis management.
