UNITED NATIONS -- US President Donald Trump urged United Nations member states on Tuesday to turn up the pressure on North Korea to give up its nuclear weapons, using his maiden speech to the world body to address what he has said is the top global challenge.
Beginning his speech shortly after arriving at UN headquarters in New York, Trump said the world faces destructive threats from rogue states and "terrorists and extremists."
"Rogue regimes not only support terrorists but threaten other nations with the most destructive weapon known to humanity," Trump said, referring to nuclear weapons.
It was Trump's first appearance in the green-marbled U.N. General Assembly hall, where applause from world leaders is generally muted.
"Big day at the United Nations - many good things, and some tricky ones, happening. We have a great team," Trump wrote hours before his address in an early morning post on Twitter that also noted his "big speech."
