June 19 (UPI) -- Scheduled talks to implement the U.S.-Iran memorandum aimed at de-escalating their war have been postponed, Switzerland said Friday, hours before the meeting was to be held.

Bern's Foreign Ministry said the planned talks have been "postponed." Neither a reason nor a new date was given.

"Switzerland remains ready to facilitate these talks," it said in a statement. "The relevant preparatory work at Burgenstock is continuing."

U.S. President Donald Trump signed the memorandum of understanding Wednesday while in Paris.
