FEARS are growing North Korea could test a nuke or launch a ballistic missile next Tuesday to mark the founding of its governing communist party.
North Korea often tests nukes or rockets on key state anniversaries. This includes the birthdays of those in the ruling Kim dynasty.
Japanese Defence Minister Itsunori Onodera raised fears of a provocative act on that day which also marks the start of an election campaign in Japan.
He said October 10 marks an important anniversary for North Korea – the date marking the founding of the North Korean communist party.
"I understand it is an important anniversary for North Korea. We would like to maintain a sense of urgency."
