More than 100 countries will have to meet higher standards on the protection of nuclear facilities and materials from next month, the U.N. nuclear watchdog said on Friday.
Nicaragua on Friday formally completed ratification of an amendment to the Convention on the Physical Protection of Nuclear Material, meaning enough states have ratified it for it to go into force, the International Atomic Energy Agency said.
"(The amendment) will help reduce the risk of a terrorist attack involving nuclear material, which could have catastrophic consequences," IAEA chief Yukiya Amano said in a statement.
The convention was adopted by 152 countries . . .
