Live Updates: U.S.-Iran deal signing gets more ships moving in Strait of Hormuz, but big challenges remain

Switzerland's government confirmed Thursday that 'initial negotiations' under the U.S.-Iran agreement were set to begin at a Swiss lakeside resort on Friday.

'Currently, the plan remains for the United States and Iran, along with the mediators Pakistan and Qatar and other involved countries, to meet tomorrow at the Burgenstock for initial negotiations on the implementation of the agreement,' the Swiss foreign ministry said in a statement.

The announcement lifted a veil of uncertainty that had hung over the meeting at the Burgenstock luxury hotel complex near Lucerne in central Switzerland, initially announced on Tuesday.

At the time, it had been billed as a signing ceremony of the memorandum of understanding, but the signing was unexpectedly moved forward, with President Trump laying down his signature Wednesday at a candlelit dinner outside Paris, as Iranian President Masoud Pezeshkian signed remotely.

The Israeli military said Thursday that forces deployed in southern Lebanon would remain there, and 'continue to remove threats' and strengthen defenses in the area.

The Israeli military announced on Thursday that one of its soldiers had been killed in fighting in southern Lebanon the day before in an incident that also wounded seven soldiers. Master Sgt. Alexander Filin, 29, 'fell in combat,' the military said in a brief statement.

Iran's foreign minister said earlier this week that if Israeli forces remain in Lebanon, it would be considered a violation of the U.S.-Iran deal, which calls explicitly for 'the immediate and permanent end to military operations on all fronts, including in Lebanon.'

The U.S.-Iran memorandum of understanding will take 'immediate effect' now that the presidents of both countries have signed it, said Pakistani Prime Minister Shebhaz Sharif, who helped mediate talks between the two sides.

President Trump and Iranian President Masoud Pezeshkian signed the memorandum of understanding on Wednesday, a U.S. official told CBS News. Mr. Trump later told reporters that he signed the deal in Versailles while taking part in a reception hosted by French President Emmanuel Macron after attending the G7 summit.

In Iran's system of government, the most powerful official is not the president, but Supreme Leader Mojtaba Khamenei.
