Donald Trump has used his annual address to the United Nations to attack Iran's "corrupt dictatorship", accusing it of sowing "chaos, death and destruction".
The US President defended his decision to abandon the nuclear deal and promised more sanctions against Tehran.
He also used the speech to boast about the accomplishments of his administration.
Trump began his speech much as he would a campaign rally: by boasting that his administration "has accomplished more than almost any administration in the history of our country."
Many of the assembled world leaders and foreign dignitaries responded with laughter.
"I didn't expect that reaction, but that's OK," he said, laughing off the chuckles that rippled through the hall.
Trump's second-ever address to the international body served to reaffirm to a domestic political audience, just as much as to the world, Trump's continued commitment to the policies and convictions that he has unleashed on the world in the year since he last addressed the UN.
