North Korea will continue to test missiles despite international condemnation and increasing military tensions with the US, a senior official has told the BBC in Pyongyang.
"We'll be conducting more missile tests on a weekly, monthly and yearly basis," Vice Foreign Minister Han Song-Ryol told the BBC's John Sudworth.
He said that an "all out war" would result if the US took military action.
Earlier, US Vice-President Mike Pence warned North Korea not to test the US.
He said his country's "era of strategic patience" with North Korea was over.
Mr Pence arrived in Seoul on Sunday hours after North Korea carried out a failed missile launch.
