Iran's negotiating team is travelling to Switzerland for talks with the United States on implementing their interim agreement aimed at ending the recent conflict, Iranian state television reported on Saturday.

The broadcaster, citing Foreign Ministry spokesperson Esmail Baghaei, said the trip had been rescheduled after an earlier plan to hold the talks on Friday was cancelled.

The announcement came shortly after Iran's joint military command said the Strait of Hormuz had been closed again, blaming continued Israeli attacks in Lebanon.

Speaking to state television, Baghaei said that any agreement ultimately faces its real test during the implementation phase.

Iranian officials had earlier refused to travel to Switzerland, insisting that the fighting between Israel and Hezbollah in Lebanon must stop before the negotiations could proceed. US Vice President JD Vance also postponed his planned trip.

Baghaei told the semi-official ISNA news agency that Pakistan's interior minister would visit Iran as part of ongoing diplomatic efforts related to the negotiations. He added that consultations through mediators were continuing regarding the next phase of talks to draft a final agreement between Tehran and Washington.

According to Baghaei, the Switzerland meeting was not considered urgent because the initial agreement had already been signed digitally earlier this week, and plans were being made to hold the discussions in the coming days.

The Swiss Foreign Ministry confirmed that diplomats were meeting on Saturday in the town of Bürgenstock to discuss implementation of the US-Iran agreement, although it did not provide further details.
