Washington - US President Donald Trump on Thursday said no one is authorised to speak to Iran on behalf of the United States, and he accused French President Emmanuel Macron of sending "mixed signals" to Tehran over possible talks.
"I know Emmanuel means well, as do all others, but nobody speaks for the United States but the United States itself," Trump said in a series of tweets.
It was not immediately clear what Trump was referring to, but a report earlier this week said Macron had invited Iranian President Hassan Rouhani to this month's G7 summit to meet Trump.
A French diplomat denied the report on Wednesday.
Representatives for the White House did not immediately respond to a request for comment on Trump's Iran tweets.
