The US and Iran are trading threats, with the President warning a massive naval armada is moving towards the country. 

Donald Trump says time's running out for Iran to make a deal to limit its nuclear programme. 

The BBC reports satellite images show a steady and significant build-up of US military forces in the region since a brutal crackdown on demonstrations in Iran earlier this month. 

US Correspondent Jagruiti Dave told Ryan Bridge Iran's mission to the United Nations has responded to Trump's latest warning. 

She says they're ready for dialogue based on mutual respect, but if pushed it'll defend itself and respond like never before.
