Donald Trump has accused Iranian leadership of sowing death and destruction across the Middle East.
The US president blasted the "corrupt dictatorship" of Iran and accused the government in Tehran of spreading "mayhem" across the Middle East and around the world, during his address at the General Assembly of the United Nations, in New York.
He also called out Iran's "bloody agenda" in Syria and Yemen.
No other country faced as much criticism in his speech to the UN General Assembly.
Mr Trump vowed the US would continue to isolate Iran through sanctions that are being reinstated after his withdrawal from the 2015 nuclear deal.
Speaking at the UN, Mr Trump spoke out against Iran and regarded them as "sponsors of terrorism" during his speech.
"We cannot allow the world's leading sponsor of terrorism to possess the planets most dangerous weapons."
He added: "We cannot allow a regime that chants 'death to America' and that threatens Israel with annihilation, to possess the means to deliver a nuclear warhead to any city on earth - just can't do it."
Arriving two hours behind schedule, Mr Trump took the opportunity to open his address with his triumphs since taking office.
He said: "In less than two years, my administration has accomplished more than almost any administration in the history of our country".
Rather than applaud or indicate they were impressed, the audience began to chuckle and some broke into outright laughter.
Mr Trump appeared briefly flustered before joking that it was not the reaction he expected but "that's all right".
