U.S. President Donald Trump said on Sunday he had told his representatives not to rush into any deal with Iran, as his administration played down hopes of an imminent breakthrough in the three-month-old war that had been raised a day earlier.

The U.S. blockade on Iranian ships in the Strait of Hormuz would ¡°remain in full force and effect until an agreement is reached, certified, and signed,¡± Trump wrote on Truth Social. ¡°Both sides must take their time and get it right,¡± he added.

There was no immediate response from Iran¡¯s government. But ?Tasnim news agency, which is linked to Iran¡¯s Revolutionary Guards, said the U.S. was still obstructing parts of a potential deal, including Tehran¡¯s demand for the release of frozen funds.
