President Donald Trump on Sunday warned Iran of consequences “the likes of which few throughout history have ever suffered,” if it threatens the United States.
The entire tweet was written in capital letters.
The response came after Rouhani earlier Sunday issued his own warning to the US leader not to “play with the lion’s tail,” saying that conflict with Iran would be the “mother of all wars”.
The high-stakes verbal sparring is reminiscent of the exchanges Trump had last year with North Korean leader Kim Jong Un before tensions eased and the two leaders met this year in a historic summit.
Trump has made Iran a favourite target since his unexpected rapprochement with nuclear-armed North Korea.
