President Donald Trump has warned North Korea it should be “very, very nervous” if it does anything to the US.
He said the regime would be in trouble “like few nations have ever been” if they do not “get their act together”.
His comments came after Pyongyang announced it had a plan to fire four missiles near the US territory of Guam.
Speaking on Thursday at his golf club in Bedminster, New Jersey, Mr Trump suggested his own statements on North Korea had not been tough enough, despite his threat this week to rain “fire and fury” upon the regime.
“I will tell you this, if North Korea does anything in terms of even thinking about attack of anybody that we love or we represent or our allies or us they can be very, very nervous.
“I’ll tell you why… because things will happen to them like they never thought possible,” he said.
However, he added that the US would always consider negotiations.
“I will tell you this, North Korea better get their act together or they’re gonna be in trouble like few nations have ever been,” he added.
He said he had “taken over a mess”, but was going to make it “a lot less messy”.
North Korea has dismissed his dire warnings as “nonsense”.
Tensions have escalated in recent weeks after North Korea tested two intercontinental ballistic missiles in July.
The UN recently approved further economic sanctions against Pyongyang over its nuclear weapons programme.
North Korea said on Wednesday it planned to fire medium-to-long-range rockests towards Guam, where US strategic bombers are based.
However, there has been no indication that any attack on the Pacific island is imminent. – BBC
