WASHINGTON (Reuters) - Only six more nations need to ratify an amendment to a nuclear security convention that would make it legally binding for countries to tighten protection of nuclear facilities and materials, the head of the International Atomic Energy Agency said on Wednesday.
IAEA Director Yukiya Amano told reporters that the measure should take effect "in the near future" after Serbia and the Marshall Islands formally ratified it on Wednesday and more countries were expected to submit paperwork on Thursday or Friday. It was not immediately clear which countries they were.
