President Donald Trump said the US is holding direct talks with Iran and the next round will take place this Saturday “at almost the highest level,” provoking confusion after the leaders in Tehran rejected the idea and proposed negotiations with Oman as mediator.

The president said talks would happen “at almost the highest level” but declined to say where the negotiations would take place or who would speak on behalf of the U.S.

President Donald Trump said Monday that the U.S. has started “direct” talks with Iran over its nuclear program, and that his administration would have a meeting with “high level” officials on Saturday.
