VIENNA - The head of the body overseeing an international nuclear test-ban treaty on Tuesday lauded the plummeting number of nuclear weapon explosive tests in the 30 years since its adoption in 1996 by the United Nations as an "amazing success."

Robert Floyd, executive secretary of the Comprehensive Nuclear Test Ban Treaty Organization, said in an interview with Kyodo News that over 2,000 nuclear weapon explosive tests were conducted prior to the treaty, but they fell to "less than a dozen" after, with North Korea the only remaining state conducting such tests.
