North Korean leader Kim Jong-un has proven an unwelcome guest four days into President Donald Trump's 17-day vacation to his golf club in Bedminster, New Jersey. 

Overnight, Trump threatened to unleash “fire and fury” against North Korea if it endangered the United States. It followed a statement from the North Korean Army, carried by the state-run KCNA news agency, that it was considering a strike on Guam, the western Pacific island home to a critical US Air Force base. 

"[Kim Jong-un] has been very threatening, beyond a normal statement," Trump said. "North Korea best not make any more threats to the United States. They will be met with fire and fury and frankly power, the likes of which the world has never seen before."

His stark response was a significant step-up in rhetoric for the US president, who'd spent the first several days of his vacation instead tweeting attacks on The New York Times, The Washington Post, Amazon, Democratic senator Richard Blumenthal, the Clintons and former US attorney-general Loretta Lynch.
