North Korea ’could trigger US military response’ if diplomacy does not work

US Secretary of State Rex Tillerson has warned that if North Korea does not choose to negotiate on giving up its nuclear weapons it could trigger a military response.

After a meeting of US allies on how to beef up the campaign of sanctions, Mr Tillerson stressed that the Trump administration seeks a diplomatic resolution in the nuclear standoff, but he said the North has yet to show itself to be a "credible negotiating partner."
