GENEVA — Diplomats from several countries were meeting Saturday at a Swiss retreat in a bid to maintain dialogue on the preliminary United States-Iran deal to halt the Middle East war, said Bern.

A diplomatic source told AFP the discussions under way on Saturday were preparatory in nature.

Senior-level talks at the hotel complex were initially planned for Friday, but were called off, with the process shrouded in layers of uncertainty, as Israel carried out deadly strikes in southern Lebanon on Saturday.

Swiss public broadcaster RTS said technical delegations from the U.S. and Iran, plus from mediators Qatar and Pakistan, were present at the discussions.

“Switzerland continues to provide a discreet and reliable setting to facilitate talks at Burgenstock on the implementation of the memorandum of understanding between the U.S. and Iran,” the foreign ministry said in a brief statement.

“Diplomats from various countries currently present are continuing their efforts to maintain the dialogue.

“No further information can be provided regarding those present or the discussions,” it added.

Israeli strikes

Israel carried out deadly strikes in south Lebanon on Saturday and Hezbollah maintained it had the right to respond, hours after the U.S. announced a renewed ceasefire in fighting that had strained the fledgling deal with Iran.

U.S. President Donald Trump and his Iranian counterpart Masoud Pezeshkian this week signed a preliminary agreement to halt the war on all fronts, including Lebanon.

But follow-up talks scheduled for Friday at the Burgenstock were indefinitely postponed as the fresh fighting in Lebanon flared.

Katara Hospitality, owned by Qatar’s sovereign wealth fund, took over the Burgenstock complex in 2007.

Swiss Foreign Minister Ignazio Cassis said late Friday that he had met earlier in the day with Qatar’s Prime Minister Mohammed bin Abdulrahman Al Thani at the resort.

The pair “exchanged views on recent regional developments following the memorandum of understanding between the U.S. and Iran,” Cassis said on X.

“As countries that place great importance on mediation, dialogue and good offices, Switzerland and Qatar share a strong commitment to supporting diplomatic solutions to international challenges.

“I thanked Qatar for its important mediation efforts and reaffirmed Switzerland’s readiness to support initiatives aimed at de-escalation, stability and lasting peace.”
