Trump threatens North Korea with "big trouble" over Guam

Tensions have risen since North Korea tested two intercontinental ballistic missiles in July.

The regime was further angered by last week's UN decision to increase economic sanctions against it.

North Korea said it was finalising a plan to fire medium-to-long-range rockets towards Guam, where US strategic bombers are based, along with more than 160,000 US citizens.

There has been no indication that any actual attack on the Pacific island is imminent.

On Thursday Mr Trump suggested that his own statements on North Korea had not been tough enough, warning the regime to be "very, very nervous".

However, he added that the US would always consider negotiations.

He also chided the North's closest ally, China, saying it could do "a lot more".

China's state-run Global Times newspaper wrote that Beijing should stay neutral if North Korea launches an attack that threatens the US.

But it also said that if the US and South Korea attacked North Korea to force regime change, then China must intervene to prevent it.
