North Korea is least capable of keeping nuclear materials secure among the 25 countries that possess the largest amounts of nuclear materials, a report concluded.
According to the U.S.-based nongovernmental organization Nuclear Threat Initiative, North Korea scored 30 out of a possible 100 on its nuclear material security index.
The index was compiled by analyzing a range of factors including adherence to international standards and management capabilities of the countries that hold 1 kilogram or more of highly enriched uranium, plutonium and other such materials.
