WASHINGTON - US President Donald Trump said on Sunday that he has told US negotiators not to rush into a deal with Iran because "time is on our side."

"The Blockade will remain in full force and effect until an agreement is reached, certified, and signed," he said in a post on Truth Social. He added: "Both sides must take their time and get it right."

The president reiterated that Iran will not be allowed to develop or procure a nuclear weapon.

He also said the "negotiations are proceeding in an orderly and constructive manner."

An Israeli government source said on Sunday that Trump has told Israeli Prime Minister Benjamin Netanyahu that he would not sign a final deal with Iran unless Tehran dismantled its nuclear program and removed all enriched uranium from its territory.

Iranian Foreign Ministry spokesman Esmaeil Baghaei said Saturday that Iran and the United States are working to finalize a memorandum of understanding on ending the war.
