Promise to halt nuclear tests big step by Kim Jong Un - but it's happened before, analysts warn

WASHINGTON - Mr Kim Jong Un's pledge to suspend nuclear and ballistic missile tests, dismantle a major nuclear testing site, and refrain from proliferation of weapons technology is a big step by the North Korean leader but analysts warn that this does not necessarily mean denuclearisation.

The United States' leadership has welcomed Mr Kim's announcement with President Donald Trump tweeting: "North Korea will stop nuclear tests and launches of intercontinental ballistic missiles. Also will shut down a nuclear test site in the country's Northern Side to prove the vow to suspend nuclear tests. Progress being made for all!"
