President Donald Trump said Saturday that the United States was in the final stages of negotiations to extend a ceasefire in the U.S. war against Iran and to reopen the Strait of Hormuz.

“An Agreement has been largely negotiated, subject to finalization between the United States of America, the Islamic Republic of Iran, and the various other Countries,” Trump wrote on Truth Social late Saturday afternoon. “Final aspects and details of the Deal are currently being discussed, and will be announced shortly,” he added.
