April 15 (UPI) -- U.S. President Donald Trump said peace talks with Iran "could be happening in the next two days," with American negotiators most likely to return to Islamabad where the first round of talks at the weekend ended without a breakthrough.

In an interview with the New York Post on Tuesday, Trump said talks between the sides were "happening, but, you know, a little bit slow," saying a new round of direct negotiations would probably be hosted by a country in Europe.

However, around 30 minutes after the interview had concluded, Trump called back to tell the Post that it should keep its reporter covering the talks in Islamabad in place and not bring them home.

"You should stay there, really, because something could be happening over the next two days, and we're more inclined to go there [Islamabad]. It's more likely, you know why? Because the field marshal is doing a great job," Trump said, referencing Pakistan's Field Marshal Gen. Asim Munir who has a direct line of communication with the regime in Tehran and a strong relationship with Trump.

"He's fantastic, and therefore it's more likely that we go back there. Why should we go to some country that has nothing to do with it?" added Trump.
