US national security adviser puts Iran 'on notice'
President Donald Trump's national security adviser has said the administration is putting Iran "on notice" after it tested a ballistic missile.
Michael Flynn told reporters that the Trump administration "condemns such actions by Iran that undermine security, prosperity and stability throughout and beyond the Middle East that puts American lives at risk".
He said "Iran is now feeling emboldened", criticising the Obama administration for failing "to respond adequately".
Mr Flynn said that "we are officially putting Iran on notice", although it is not clear what he meant.
A defence official said this week that the missile test ended with a "failed" re-entry into the earth's atmosphere.
The official had no other details, including the type of missile.
