NATO allies are still trying to establish the facts about a missile which hit eastern Poland, near the Ukranian border, yesterday and killed two Polish people.
Police have blocked access to the missile landing site in eastern Poland and the government there says there is no conclusive evidence as to who launched the missile.
Russia's defence ministry denies it was responsible and says accusations are a "deliberate provocation aimed at escalation".
University of Otago professor of politics and international relations Dr Robert Patman spoke to Māni Dunlop.
