Tehran says it remains steadfast on its principled red lines as authorities review a proposed understanding, firmly rejecting speculation that a final deal has been reached despite Washington backtracking on recent military threats.

Following claims made by US President Donald Trump on Thursday about an imminent deal between Tehran and Washington, an informed source told Tasnim News Agency that the text of the understanding has not been approved up to this moment.

Meanwhile, Foreign Ministry spokesperson Esmaeil Baghaei confirmed that major sections of a potential understanding are close to completion. However, he rejected media speculations regarding a finalized agreement.

"Textually, the text has almost been finalized in its major parts. The problem is that the contradictory positions of the United States have always caused turbulence and disruption in this process," Baghaei stated.
