Iran’s Foreign Minister Mohammad Javad Zarif has dismissed US President Donald Trump’s “genocidal taunts” and warned him not to threaten the country.
Amid rising tensions, Mr Trump tweeted on Sunday: “If Iran wants to fight, that will be the official end of Iran.”
Mr Zarif said the US president should look to history. “Iranians have stood tall for millennia while aggressors all gone… Try respect – it works!”
The US has deployed additional warships and planes to the Gulf in recent days.
But Mr Trump’s tweet marked a shift in tone after recent attempts by him to downplay the possibility of a military conflict with Iran. When asked by reporters on Thursday if the US was going to war, he said: “I hope not.”
Iranian state media reported on Monday that the country had increased by fourfold its production of low-enriched uranium, which was limited to a 300kg stockpile by the 2015 nuclear deal between Iran and world powers.
