US President Donald Trump has warned Iran not to "f*** around" with the US.
Trump used the expletive during a radio interview with Rush Limbaugh earlier today.
The remarks were censored by the stations that aired the interview.
"Iran knows that and they've been put on notice: If you f*** around with us, if you do something bad to us, we are going to do things to you that have never been done before," Trump said.
