US President Donald Trump escalated his rhetoric against North Korea tonight, suggesting he had "not been tough enough" when he warned the rogue regime faced "fire and fury".

Mr Trump said North Korea should be "very, very nervous" about doing anything to the United States or its allies.

He said: "It's about time somebody stuck up for the people of this country and for the people of other countries. So if anything, maybe that statement wasn’t tough enough."

The president was vague about what further action his administration might take, telling reporters: "You’ll see. You’ll see."

Mr Trump added: “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. Because things will happen to them like they never thought possible, OK? He’s been pushing the world around for a long time."
