Trump sounds further warning to North Korea

Donald Trump has warned North Korea it should be “very very nervous” if their military takes any action against American territories.

The U.S president has been criticised for his strong language as tensions between the two countries escalate – but he says his threat to rain “fire and fury” on Pyongyang ‘might not have been tough enough’.

However US Defence Secretary James Mattis says their effort is “diplomatically led”.
