Renewed alarm over French nuclear weapons tests.in the Pacific

There is renewed alarm in French Polynesia over the legacy of the French nuclear weapons tests.

Last week's release of a new study led to fresh accusations that the French authorities misled the public about the seriousness of the test fallout.

For the pro-independence opposition, Paris now needs to explain its testing regime to the United Nations.

Walter Zweifel followed the debate and I asked him what triggered the latest concerns.
