US President Donald Trump dramatically raised the possibility of military action against Iran over its missiles test on Thursday saying 'nothing is off the table', the Daily Mail reported on Thursday.
He used the phrase when asked directly if military action was possible - and after a series of angry tweets about how Iran tested a ballistic missile – something the nuclear bargain it struck with Barack Obama explicitly forbids.
Trump was speaking in the Roosevelt Room of the White House as he met executives from Harley Davidson, the motorcycle makers, and after Tehran had called his threats 'useless' and described him as 'an inexperienced person'.
As he spoke it also emerged that Iran has tested a cruise missile called 'Sumar' that is capable of carrying nuclear weapons.
The development was reported by German newspaper Die Welt reported Thursday, citing unspecified intelligence sources.
It will only escalate anger which had seen Trump earlier use social media to issue an explicit warning to Tehran.
'Iran has been formally PUT ON NOTICE for firing a ballistic missile,' the president wrote on Twitter.
'Should have been thankful for the terrible deal the U.S. made with them!'
'Iran was on its last legs and ready to collapse until the U.S. came along and gave it a life-line in the form of the Iran Deal: $150 billion,' he added in a second tweet.
Trump has been openly hostile to the terms of the Obama-Tehran nuclear deal, saying during his presidential campaign that it was 'stupid,' 'a disgrace,'' and 'the worst deal ever negotiated.'
His tweets likely stand as the first time a head of state has used social media to threaten a foreign country.
They were met with contempt by the Iranian regime.
