Comprehensive Nuclear Test Ban Treaty Organization

North Korea's recent nuclear test shows a ratification of an international ban on nuclear bomb tests is more urgent than ever, the head of the Vienna-based organisation tasked with enforcing the ban said on Monday.

The head of the UN nuclear test ban treaty organization says arch-enemies Iran and Israel are "the closest" of the eight holdout nations to ratifying the treaty and assuring the world they will never conduct a nuclear test explosion.
