Donald Trump struck a defiant stance against North Korea on Tuesday afternoon, warning of severe retribution should the authoritarian state proceed with any more missile tests or threats. In a statement delivered at his Bedminster, New Jersey golf club, Trump said, "North Korea best not make any more threats to the U.S. They will be met with fire and fury like the world has never seen."

His comments follow on from reports that North Korea had successfully produced a nuclear warhead that could be fitted inside its missiles. The U.N. Security Council unanimously voted on Saturday to impose new sanctions on North Korea after several missile tests.

Officials in North Korea said they were "carefully examining" a strike on Guam, which is home to around 163,000 people and two U.S. military installations and threatened a further "all-out war wiping out all the strongholds of enemies, including the U.S. mainland" in a government statement.
