Fox News now reports the wording of Trump's warning to Tehran. According to the outlet, Trump said on Thursday 12 November that Iran would "not exist very long" if the regime assassinated a senior US official.
Earlier coverage had described the warning only in general terms. Fox News and Al Jazeera reported that Trump said he would not hesitate to launch new strikes.
Fox News reports that the warning came amid reports that Treasury Secretary Scott Bessent had been moved to a military base after threats linked to Tehran.
The full remark and its context have not been independently checked.
