Iran's president said on Wednesday that there was no chance of negotiations or compromise with the United States, allegedly because Washington is seeking to topple the government in Tehran.
In a televised speech, Hassan Rouhani said "the United States says Iran should change" back to the way the country was before the 1979 Islamic Revolution, when it was ruled by a US-supported monarchy.
"We say we won't go back," Rouhani said at a gathering in the northern city of Lahijan.
He said the differences between Iran and the US are so wide, they are "neither negotiable nor can there be a compromise."
