US President Donald Trump has launched an explosive all-caps Twitter threat on Iran declaring “you will suffer consequences the likes of which few have ever suffered before.”

Donald Trump’s tweet follows Iranian President Hassan Rouhani cautioning the American leader on Sunday about pursuing hostile policies against Tehran, saying:

“War with Iran is the mother of all wars and peace with Iran is the mother of all peace.”

Rouhani also shared a message for Trump, saying “do not play with the lion’s tail, because you will regret it eternally.”

Donald Trump’s tweet threat to Iran President Rouhani reads:

To Iranian President Rouhani: NEVER, EVER THREATEN THE UNITED STATES AGAIN OR YOU WILL SUFFER CONSEQUENCES THE LIKES OF WHICH FEW THROUGHOUT HISTORY HAVE EVER SUFFERED BEFORE. WE ARE NO LONGER A COUNTRY THAT WILL STAND FOR YOUR DEMENTED WORDS OF VIOLENCE & DEATH. BE CAUTIOUS!
