"I would say he should be very worried, yeah, he should be," Trump said in an interview with US broadcaster NBC News. "As you know, they are negotiating with us."
Trump's comments came as a report by the Axios news outlet said that US-Iran talks planned for Friday were "collapsing" after US officials declined to move the location of the talks or shift the format.
The White House did not immediately comment on the Axios report when asked by AFP.
Trump has sent a US aircraft carrier to the region and has not ruled out new military action to follow the US attacks on Iranian nuclear sites during Israel's June war against the Islamic Republic.
Trump also said that Iran had eyed a new nuclear site after US strikes.
"They were thinking about starting a new site in a different part of the country," Trump told NBC. "We found out about it, I said, you do that, we're going to do very bad things to you."
Iranian 2023 Nobel Peace Prize winner Narges Mohammadi, jailed since her arrest in December, has gone on hunger strike, her family's Paris-based lawyer said on Wednesday.
Mohammadi, who was arrested at a protest in the eastern city of Mashhad on December 12, "has been on hunger strike for the last three days", lawyer Chirinne Ardakani told AFP.
"She is demanding her right to make a phone call, have access to her lawyers in Iran, and to be visited," Ardakani said, adding that Mohammadi's last phone call to her family dated back to December 14, and they had been informed of the hunger strike by a detainee who had been released from prison.
