Iran hits back at Trump's 'genocidal' tweet threatening to 'end' the regime as US Navy puts on a show of force amid increasing fears of war breaking out. The Iranian Foreign Minister Mohammad Javad Zarif slammed the President for his Twitter outbursts on Monday, calling them 'genocidal taunts which won't end Iran'. He wrote: @realdonaldTrump hopes to achieve what Alexander, Genghis & other aggressors failed to do. Iranians have stood tall for millennia while aggressors all gone. #EconomicTerrorism & genocidal taunts won't "end Iran". #NeverThreatenAnIranian. Try respect-it works!" 🗿
