Iranian President Hassan Rouhani warned of the possibility that Iran could drop out of its 2015 nuclear deal, according to an AFP report.
The deal was made with a number of world powers and included the lifting of international sanctions on Iran in exchange for limits on its nuclear program.
Rouhani's warning, made in a televised address to parliament, said that Iran could abandon the deal within hours if the United States continues to impose sanctions.
Rouhani criticized US President Donald Trump, saying that he was "not a good partner."
"The failed experience of sanctions and coercion brought their previous administrations to the negotiating table," Rouhani said in the televised address.
"If they want to go back to that experience, definitely in a short time - not weeks or months, but in the scale of hours and days - we will return to our previous situation very much more stronger," he said.
