Donald Trump has threatened Iran with "obliteration" if it launches any attack on US forces, in a Twitter rant railing against an "ignorant and insulting statement" by Tehran.
"Iran’s very ignorant and insulting statement, put out today, only shows that they do not understand reality", Mr Trump tweeted Tuesday morning.
"Any attack by Iran on anything American will be met with great and overwhelming force. In some areas, overwhelming will mean obliteration. No more John Kerry & Obama!"
