President Donald Trump has said that the U.S. and Iranian negotiators were expected to meet in the Qatari capital Doha on Tuesday, despite no confirmation from Tehran.

"IRAN HAS REQUESTED A MEETING. IT WILL TAKE PLACE TOMORROW IN DOHA," Trump wrote Monday on his Truth Social platform, without providing further details on the purpose of the talks.

Speaking later at the White House, Trump said his team had already departed or was in the process of doing so. "The meeting in Doha is going to be perhaps important, perhaps not," he said.

Iran had earlier rejected reports of an imminent round of talks with the United States. A new round of talks would take place "as soon as the conditions are in place and agreement has been reached on the date and venue," said Deputy Foreign Minister Kazem Gharibabadi, according to the Iranian news agency ISNA.

"No technical working group meetings are scheduled for this week," he added, while noting that consultations would continue via intermediaries.
